SNA LU 6.2 security services

SNA LU 6.2 offers session level cryptography, session level authentication, and conversation level authentication.

Note: This collection of topics assumes that you have a basic understanding of Systems Network Architecture (SNA). The other documentation referred to 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 8 bytes in length.
