✦ Synopsis

specifics of the networks involved. IPSec consists of two protocols: the Authentication Header, or AH protocol, and the Encapsulating Security Payload, or ESP protocol. Two authentication and seven encryption algorithms have been defined to date.The authentication algorithms used by AH and ESP are: HMAC-MD5 and HMAC-SHAl. Both are key-based algorithms where session participants share a secret key -128 bits for MD5 and 160 bits for SHAl. Encryption algorithms are as follows: DES, triple DES, CAST-128, RC5, IDEA, Blowfish and ARCFour. Specifying IPSec algorithms requires a session management protocol covered by ISAKMP (Internet Security Association Key Management Protocol) and Oakley protocol. However, because ISAKMP and Oakley are not designed specifically for IPSec, a domain of interpretation (DOI) is required.
