Compaq 850 manual Ipsec Function

Appendix I Compaq/Intel Network Interface Controller Adapters

I.2.3 IPSEC FUNCTION

The 82550 controller used on the Intel PRO/100 S Management Adapter includes an encryption engine that provides on-the-fly encryption and/or authentication of transmit data without additional use of system memory and software. This function, referred to as IP security (IPSEC), uses a configurable algorithm and established Data Encryption Standards (DES) to provide high performance (full transmission rate) encryption. Received IPSEC data frames are re-submitted to the controller for processing and then returned to the driver.

Key features of IPSEC support include:

♦Encryption capability of 56-bit DES to 168-bit 3DES

♦Out-of-order processing of non-security transmit frames during security mode

♦SHA-1 and MD-5 authentication with optional HMAC cryptographic hashing
