IPsec Anti-Replay Algorithm without Bit Shifting
RFC 6479, “IPsec Anti-Replay Algorithm without Bit Shifting”, is an Informational document published in January 2012 by X. Zhang, T. Tsou. The canonical text is published by the RFC Editor.
Abstract
This document presents an alternate method to do the anti-replay checks and updates for IP Authentication Header (AH) and Encapsulating Security Protocol (ESP). The method defined in this document obviates the need for bit shifting and it reduces the number of times an anti-replay window is adjusted. This document is not an Internet Standards Track specification; it is published for informational purposes.
