SNA LU 6.2 security services

 

This section assumes that you have a basic understanding of Systems Network Architecture (SNA). Each of the books referenced in this section contains a brief introduction to the relevant concepts and terminology. If you require a more comprehensive technical introduction to SNA, see Systems Network Architecture Technical Overview, GC30-3073.

SNA LU 6.2 provides three security services:

• Session level cryptography

• Session level authentication

• Conversation level authentication

For session level cryptography and session level authentication, SNA uses the Data Encryption Standard (DES) algorithm. The DES algorithm is a block cipher algorithm, which uses a symmetric key for encrypting and decrypting data. Both the block and the key are eight bytes in length.
