Introduction

Overview

The Verilink Access System 2000 Red Zone Encryption Management

System (REMS) is a T1-compatible system for communicating KG-XX

encrypted data

between two Red Zones across a Black Zone public or

private network while monitoring network management parameters from

the Red Zone.

The secure area from a DTE to an encryptor is called the

Red Zone

. The

non-secure public media between encryptors is called the

Black Zone

1. The purpose of encryption is to alter intelligent data, producing an unintelligent

bit stream for transport across the non-secure public media. Inversely, the

encryption process is reversed at the destination, reproducing the original intelli-

gent data.
