Abstract:
Announcements in the past decade of better-than-expected collision
attacks in popular hash algorithms have caused some people to
question whether common Internet protocols need to be changed, and if
so, how. This document summarizes the use of hashes in many
protocols, discusses how the collision attacks affect and do not
affect the protocols, shows how to thwart known attacks on digital
certificates, and discusses future directions for protocol designers.
It also gives rationales for moving away from some hash algorithms
altogether and for choosing when to start using newer, presumably
better, hash algorithms in Internet protocols.
This document obsoletes RFC 4270 and introduces significant new
material that has been learned since the publication of that
document.
