3e-531AP Wireless Access Point

Chapter 1: Introduction

29000125-001 C

Chapter 1: Introduction

This manual covers the installation and operation of the 3e Technolo-

gies International’s 3e-531AP Wireless Access Point, which conforms to

the requirements of FIPS PUB 140-2, Security Requirements for Crypto-

graphic Modules. The 3e-531AP Wireless Access Point provides a connec-

tion between an Ethernet LAN and a wireless LAN (WLAN). The wireless

LAN can include mobile devices such as handheld Personal Data Assis-

tants (PDAs), mobile web pads, and wireless laptops as long as they have

the 3e-010F Crypto Client software installed. (The 3e-010F Crypto Client

software is sold with the 3e-110 long range PC Card or sold separately for

use with other compatible PC Cards.)

The 3e-531AP incorporates Power over Ethernet (PoE), IEEE 802.3af,

and the highest security functionality including the ability to manage RF

centrally and to even shut off RF to wireless devices entirely, should that

be necessary. The PoE solution eliminates the need for internal gateway

power supply units (AC-DC converters) and 110-220V cabling installa-

tions for the gateway operation. In the 3e-531AP, however, the capability

to switch to AC power has been provided as a backup in the event the

Power over Ethernet hub is lost or unavailable. The device detects power

failure and automatically switches to AC current with minimal wireless

connection interruption using the power cord provided. (Note: a power

cord does not have to be plugged in to the 3e-531AP during setup, but it

is recommended that it be kept available for use in case of failure of the

PoE Power Supply.)

The PoE interface on the 3e-531AP is compatible with commercial

vendor “injected power” hub units (also known as Ethernet Power Sup-

ply or Power over Ethernet Hub) interfaces.

The 3e-531AP conforms to the FIPS 140-2 speci cation. It includes

the following cryptographic modules: AES/3DES for wireless encryption;

dynamic key exchange (Dif e-Hellman module 1024) for wireless com-

munication; and HTTPS/TLS, for secure web communication. The 3e-

531AP contains three cryptographic modules and ports: Ethernet WAN

uplink interface for communication to the wired LAN backbone; Ethernet

LAN local port for communication to a local wired LAN; and wireless

LAN port for wireless communication to local clients. The authorized

roles supported are Crypto Of cer Role and Administrator Role. Crypto-

graphic services provided include; AES and 3DES for wireless; SHA-1 for

authentication; HMAC SHA-1 for keyed authenticated  rmware upgrade;

3e-531AP Wireless Access Point

Chapter 1: Introduction

29000125-001 C

Dif e-Hellman Key Exchange; and HTTPS/TLS for web services via a

secure link. Operator Authentication is performed by assigning operator

type: Administrator can view con gurations and logs, can do non-cryp-

tographic functions such as assigning hostname, domain name, system

date/time, TX Pwr Mode/Level and the like; the Crypto Of cer role has

total access and control and can perform cryptographic initialization or

management functions such as module initialization, input or output of

cryptographic keys and CSPs, and audit functions.

The 3e-531AP is wall-mountable and physically sealed with special

tape for physical security. Violation of the unit's integrity will cause the

unit to fail and display an Error State alarm, requiring reboot.

Basic Features

The 3e-531AP is housed in a sturdy case which is not meant to be

opened except by an authorized technician for maintenance or repair. The

unit should work without fail. If you wish to reset to factory settings, use

the reset function available through the web-screen management module.

It has the following features:

•

Wireless Basics

Wireless networking uses electromagnetic radio frequency waves to

transmit and receive data. Communication occurs by establishing radio

links between the wireless gateway and devices con gured to be part of

the

WLAN.

The 3e-531AP incorporates the 802.11b (Wi-Fi) standard and

the most

state of the art encryption for a very powerful and secure wireless envi-

ronment.

802.11b

The IEEE 802.11b standard, developed by the Wireless Ethernet

Compatibility Alliance (

WECA), establishes a stable standard. A user with

an 802.11b product can use any brand of gateway/access point with any

other brand of client hardware that is built to the 802.11b standard for ba-

sic interconnection.

802.11b devices provide 11 Mbps transmission (with a

fallback to 5.5, 2 and 1 Mbps depending on signal strength) in the 2.4 GHz

band.

802.11b uses

DSSS (direct-sequence spread spectrum) for radio com-

munication.

Direct-sequence systems communicate by continuously

transmitting a redundant pattern of bits called a chipping sequence. The

chipping sequence is combined with a transmitted data stream to produce

the wireless output signal.

For wireless devices to communicate with the 3e-531AP, they must

meet the following conditions:

•

The signal strength must be suf cient;

•

The wireless device and wireless gateway must have been con g-

ured to recognize each other using the

SSID (a unique ID assigned

in setup so that the wireless device is seen to be part of the net-

work by the 3e-531AP);

•

Encryption and authentication capabilities and types enabled

must conform;

•

The wireless device and wireless gateway must have compatible

data rate con gurations; and

•

If MAC  ltering is used, the 3e-531AP must be con gured to

allow the wireless device’s MAC address to associate (communi-

cate) with the 3e-531AP wireless interface.

3e-531AP Wireless Access Point

Chapter 1: Introduction

29000125-001 C

Network Con guration

The 3e-531AP is capable of various con gurations. The three basic

con gurations are:

•

Access point mode with wired infrastructure

•

Gateway mode with wired infrastructure

•

Wireless bridging with choice of:

— Point-to-point setup

— Point-to-multipoint setup

— Repeater setup

Bridging actually has more choices, but the above choices are popular

and are discussed later in this user guide.

Access Point Con gurations

When a 3e-531AP is con gured as an access point, IP addresses for

wireless devices are typically assigned by the wired network’s

DHCP

server. The wired LAN’s DHCP server assigns addresses dynamically,

and the AP virtually connects wireless users to the host wired network.

All wireless devices connected to the AP are con gured on the same sub-

network as the attached wired network interface and can be accessed by

devices on the wired network.

Possible AP Topologies

1.

An access point can be used as a single AP without any connec-

tion to a wired network. In this con guration, it simply provides a

stand-alone wireless network for a group of wireless devices.



2.

The 3e-531AP can be used as one of a number of APs connected

to an existing Ethernet network to bridge between the wired and

wireless environments. Each AP can operate independently of the

other APs on the LAN. Multiple APs can coexist as separate indi-

vidual networks at the same site without interference if each AP is

set with a different

network ID (SSID).

3.

And lastly, multiple APs connected to a wired network and operat-

ing off that network’s DHCP server can provide a wider coverage

area for wireless devices, enabling the devices to “

roam” freely

about the entire site.

 



Gateway Con gurations

In gateway mode, wireless users are provided additional

 rewall

protection from the rest of the industrial or shipboard network or Internet

using

Network Address Translation (

NAT) protocol features and  rewall

options.

Wireless users can still communicate with the wired network resourc-

es but communication must be initiated by the wireless devices. Using the

NAT protocol, the only IP address visible to the wired network is that of

the gateway itself, as assigned by the wired Ethernet DHCP server. The

gateway provides  rewall protection to its wireless users. It can dynami-

cally assign private addresses to member devices using its own internal

DHCP server. It acts as a

router, not a

bridge, and controls traf c  ow and

access control between the wired and wireless networks.

Alternately, if you wish, the network administrator can assign

static

addresses to the member wireless devices. In order to set static addresses,

the system administrator will need to manually con gure the TCP/IP

con guration on each wireless device.

Bridging Mode

The wireless bridging function in the 3e-531AP allows setup as a

bridge, in a number of alternate con gurations, including the following

popular con gurations:

1.

Point-to-point bridging of 2 Ethernet Links;

2.

Point-to-multipoint bridging of several Ethernet links;

3.

Repeater mode (wireless client to wireless bridge.)

Default Con guration

By default, the 3e-531AP boots up in access point mode. See your

network administrator or more advanced technical sections of this User’s

Guide for information if the device is to be con gured in gateway mode

or bridging mode.

Data Encryption and Security

The 3e-531AP Wireless Access Point includes advanced wireless

security features, including Dynamic Key Management or Static key AES

or 3DES encryption. AES or 3DES and MAC Address authentication are

available in the 3e-531AP in all modes, and some level of encryption is

recommended. In gateway mode, WEP encryption is an option.

The incorporation of AES and 3DES brings system security up to the

most stringent standards. The functionality of these two enhancements,

along with a more detailed discussion of the 3e-531AP security features,

is further covered in the following paragraphs.

3e-531AP Wireless Access Point

Chapter 1: Introduction

29000125-001 C

SSID

The Service Set ID (SSID) is a string used to de ne a common roam-

ing domain among multiple wireless access points. Different SSIDs on

gateways can enable overlapping wireless networks. The SSID can act as

a basic password without which the client cannot connect to the network.

However, this is easily overridden by allowing the wireless AP to broad-

cast the SSID, which means any client can associate with the AP. SSID

broadcasting can be disabled in the 3e-531AP setup menus.

AES and 3DES

The Advanced Encryption Standard (AES) was selected by National

Institute of Standards and Technology (NIST) in October 2000 as an up-

grade from the previous DES standard. AES uses a 128-bit block cipher

algorithm and encryption technique for protecting computerized infor-

mation. It has the ability to use even larger 192-bit and 256-bit keys, if

necessary. AES is incorporated into all current and future models of 3e

Technologies International’s series of wireless APs/gateways.

3DES is also incorporated on the 3e-531AP. 3DES is modeled on the

older DES standard but encrypts data three times over. Triple-DES uses

more CPU resources than AES because of the triple encryption.

Dynamic Key Management

Addition of Security Server software (3e-030, sold separately), which

is con gured to dynamically assign secure key access, raises the secu-

rity capability to its highest level. The Security Server software operates

from a remote point on the WLAN and is accessed by pointing to its IP

Address in each of the 3e-531APs on the WLAN as part of the wireless

encryption con guration process.

Authentication

The

MAC address, short for

Media Access Control address,

is a hard-

ware address that uniquely identi es each node of a network. In IEEE 802

networks, the

Data Link Control (

DLC) layer of the

OSI Reference Model

is divided into two sub-layers: the

Logical Link Control (LLC) layer

and the

Media Access Control (MAC) layer.

The MAC layer interfaces directly with

the network media. Consequently, each type of network media requires a

unique MAC address.

Authentication is the process of proving a client identity. The 3e-

531AP gateways, if set up to use MC address  ltering, detect an attempt

to connect by a client and compare the client’s MAC address to those on

a prede ned MAC address  lter list. Only client addresses found on the

list are allowed to associate. MAC addresses are assigned and registered

to each of the wireless cards used by the portable computing devices dur-

ing initial setup and after physical installation of the gateways.

DHCP Server and NAT

In AP mode, the 3e-531AP has a DHCP (

Dynamic Host Con guration

Protocol

) server function that is accessible to the LAN port. If the 3e-

531AP is set up in gateway mode, this DHCP function is available, with

many  rewall functions in addition, to both the LAN and WLAN ports.

DHCP is a protocol for assigning

dynamic IP addresses.

When the 3e-531AP is in access point mode, the DHCP function is

accessible only from the local LAN port. A local LAN can be established

from the LAN port and can utilize the DHCP function.

If the 3e-531AP is recon gured for gateway mode, and the DHCP

function is enabled, the gateway

Ethernet uplink interface becomes the

only visible

IP address to the Ethernet network. It uses Network Address

Translation (NAT) to forward packets from wireless devices as if they

were coming from the one visible IP address, managing a database of in-

formation in order to sort out and forward the replies to the correct client.

NAT provides an additional layer of security by protecting information

on the wireless LAN from direct access by the Ethernet LAN.

Operator Authentication and Management

Authentication mechanisms may be required within a cryptographic

module to authenticate an operator accessing the module and to verify

that the operator is authorized to assume the requested role and perform

services within that role.

There are two types of operators de ned:

•

Crypto Of cer: The Crypto Of cer user has total control of the

gateway. The Crypto Of cer can con gure the encryption keys

and upload  rmware.

•

Administrator: The Administrator can view con gurations and

logs, can do non-cryptographic functions such as assigning host-

name, domain name, system date/time, TX Pwr Mode/Level and

the like. This user can reboot the gateway if it is deemed neces-

sary.

The Crypto Of cer initially installs and con gures the 3e-531AP after

which the

password should be changed from the

default password. The

enclosure itself must be physically secured.

Management

After initial setup, maintenance of the system and programming of

security functions are performed by personnel trained in the procedure

using the embedded web-based management screens. For general mainte-

nance, the Administrator logon should be suf cient.

The next chapter covers the basic procedure for setting up the hard-

ware.

Chapter 2: Hardware Installation

Preparation for Use

The 3e Technologies International's 3e-531AP Wireless Access Point

requires physical mount ing and in stal la tion on the site, following a

prescribed placement design to ensure optimum operation and roaming.

Professional installation is required.

If the 3e-531AP's Power over Ethernet (PoE) solution is being activat-

ed, it will, in addition, re quire the installation of a separate PoE-capable

hub switch which “in jects” DC cur rent into the Cat5 cable. This injector

device should have been spec’ed and installed by a wireless LAN installa-

tion team.

To ensure that there is no possibility of danger from contact with the

in ject ed current should anyone open the 3e-531AP enclosure, each 3e-

531AP device has been  tted with a safety interlock that functions as an

in ter nal circuit breaker to interrupt the  ow of current when the device is

opened.

The 3e-531AP package includes the following items:

•

The FIPS-compliant 3e-531AP

•

2 removable antennas

•

Documentation as PDF  les (on CD-ROM)

•

Installable RF Manager utility (on CD-ROM)

•

Registration card

•

Warranty card

The following items are separately purchased in accordance with the

exact dimensions of the network to be con gured:

•

Power cable with water-resistant circular connector

•

Ethernet cable with special water-resistant circular con-

nec tor

3e-531AP Wireless Access Point

Chapter 2: Hardware Installation

29000125-001 C

The antennas used with the 525A must be installed with a mini-

mum separation distance of 20 cm from all persons, and must

not be co-located or operated in conjunction with any other

antenna or transmitter. Installation should be accomplished

using the authorized cables and/or connectors provided with the device

or available from the manufacturer/distributor for use with this device.

Changes or modi cations not expressly approved by the manufacturer or

party responsible for this FCC compliance could void the user’s authority

to operate the equipment.

Installation Instructions

The 3e-531AP is intended to be installed as part of a complete wireless

design solution, and, as such, the design and ar chi tec ture of that solution

is unique to each lo ca tion and is addressed in a separate doc u ment. Prop-

er installation of the wire less sys tem will ensure that users can “roam”

freely throughout the serviced location, passing transparently from node

to node with no loss of service but at the same time maintaining top secu-

rity on the wireless LAN.

This manual deals only and speci cally with the single 3e-531AP de-

vice as a unit. The purpose of this chapter is the description of the device

and its identi able parts so that the user is suf ciently familiar to interact

with the physical unit. Preliminary setup information provided below

is intended for information and instruction of the wireless LAN system

administration personnel.

It is intended, and is the philosophy of 3e Technologies International,

that the user not be required to open the individual unit. Any main te -

nance required is limited to the external enclosure surface, cable con nec -

tions, and to the man age ment software (as described in Chapter three,

four and  ve) only. A failed unit should be returned to the man u fac tur er

for maintenance. Sites requiring emergency backup will maintain extra

units of the device to interchange in case of failure.

Minimum System and Component Requirements

The 3e-531AP is designed to be attached to the wall or bulkhead at

appropriate locations. To complete the con guration, you should have at

least the following components:

•

PCs with one of the following operating systems installed:

Win dows Windows NT 4.0, Windows 2000 or Windows XP;

•

A compatible 802.11b PC Card or 802.11b device for each

computer that you wish to wirelessly connect to your wire-

less network. (For wireless cards, select the 3e-110 PC Card

with 3e-010F Crypto Client software (sold separately) or

install the 3e-010F software with any compatible PC Card.

(For maximum security and compatibility, we recommend

the 3e Technologies International 3e-110 PC Card);

•

Access to at least one laptop or PC with an Ethernet card

and cable that can be used to complete the initial con  g u-

ra tion of the unit. (The cable required will have a standard

RJ-45 connector on one end and a circular connector on the

other.)

•

A Web browser program (such as Microsoft Internet Explor-

er 5.5 or later, or Netscape 6.2 or later) in stalled on the PC or

laptop you will be using to con gure the Gateway.

•

TCP/IP Protocol (usually comes installed on any Windows

PC.)

Cabling

The 3e-531AP is well-protected in a met al enclosure which is gen-

er al ly bolted to the bulk head. The front of the box is hinged but should

not be opened, particularly if being employed as FIPS 140-2 compatible

device.

The fol low ing il lus tra tion shows the external cabling on the 3e-531AP.

However, even if the On-off switch is “on”, if the lid of the de vice is

opened, power will cease to  ow be cause of the safe ty in ter lock.

An AC Power Con nec tor (not provided) can be plugged into an AC

outlet. In some situations, the in stal la tion design may include elimination

of the ability to plug the unit into an AC outlet. In such circumstances, the

AC power is supplied (that is, hardwired) using the same AC Power Con-

nector port. Usually, in the default con guration of the 3e-531AP, the AC

Pow er Con nec tor is not ac tive ly used. The socket outlet must be installed

near the equipment and be easily accessible.

The Ethernet Up link con nec tor is used to connect the 3e-531AP to the

ship board LAN. When used as a PoE device, the Ethernet Uplink con-

nec tor will have been routed from the unit to a PoE-capable hub switch

which runs the power through the Ethernet cable to the unit. The Ethernet

cable is thus run from the 3e-531AP to the PoE-capable hub switch which

is then connected to the wired LAN and to a power source.

The 3e-531AP design includes an external Power Switch for the pur-

pose of disabling power to the unit for servicing or removal.

Although a safety interlock is provided on the unit to disable power

when the enclosure door is opened, AC and PoE power cables must be

disconnected prior to servicing or removing the device. This is a pre cau -

tion ary measure.

An additional Ethernet connector labeled "Local" is designated for use

during initial con guration. The installation team uses an RJ45 cable with

Circular con nec tor to connect the 3e-531AP to a laptop.

Indicator Lights

The top panel of the 3e-531AP con tains a set of in di ca tor lights (

Light

Emitting Diodes or

LEDs) that help describe the state of various network-

ing and connection operations.

This closeup shows the ground and one of the seals that

are standard on the FIPS 140-2 compliant 3e-531AP.

Note that the ground will be installed permanently on

installation of the unit and should not be disturbed after

that.
