Data Encryption Overview

Bay Networks data encryption services enable you to protect sensitive traffic on

your network. Encryption prevents unauthorized persons from reading, changing,

or replaying data that travels between Bay Networks routers.

Data encryption services include:

• Software-based encryption for PPP dedicated links for the BN

, AN

, ARN

™,

ASN

™

, System 5000

™

router modules, and all serial interfaces. This includes

encryption on multiline and multilink.

• Software-based encryption for frame relay circuits that have one permanent

virtual circuit (PVC) per service record. This includes encryption on

multiline.

• Encryption configurable on a line or circuit basis.

• Encryption independent or combined with data compression.

You can configure PPP dial backup for a frame relay circuit that uses data

encryption. Be aware, however, that if the primary circuit fails, data that travels

over the backup circuit is unencrypted.

Data Encryption Architecture

Bay Networks uses the following standards and protocols to provide encryption

services:

• Data Encryption Standard (DES)

• Message Digest 5 (MD5)

• WAN Encryption Protocol (WEP), proprietary to Bay Networks
