This memo describes the use of the HMAC algorithm [RFC 2104] in
conjunction with the RIPEMD-160 algorithm [RIPEMD-160] as an
authentication mechanism within the revised IPSEC Encapsulating
Security Payload [ESP] and the revised IPSEC Authentication Header
[AH].  HMAC with RIPEMD-160 provides data origin authentication and
integrity protection.
 
Further information on the other components necessary for ESP and AH
implementations is provided by [Thayer97a].
