Network Working Group the Advanced Encryption Standard-cipher-based Message Authentication Code-pseudo-random Function-128 (aes-cmac-prf-128) Algorithm for the Internet Key Exchange Protocol (ike)

Status of This Memo This document specifies an Internet standards track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the "Internet Official Protocol Standards" (STD 1) for the standardization state and status of this protocol. Distribution of this memo is unlimited. Abstract Some implementations of IP Security (IPsec) may want to use a pseudo-random function (PRF) based on the Advanced Encryption Standard (AES). This memo describes such an algorithm, called AES-CMAC-PRF-128. It supports fixed and variable key sizes.
