The IESG has approved following document: - 'The AES-XCBC-PRF-128 algorithm for IKE ' <draft-ietf-ipsec-aes-xcbc-prf-01.txt> as a Proposed Standard This document is the product of the IP Security Protocol Working Group. The IESG contact persons are Russ Housley and Steve Bellovin. Technical Summary Some implementations of IPsec may want to use a pseudo-random function derived from AES. This document describes such an algorithm, called AES-XCBC-PRF-128. Working Group Summary The IPsec Working Group came to consensus on this document. Protocol Quality This document was reviewed by Russell Housley for the IESG.
