RFC 4418, "UMAC: Message Authentication Code using Universal Hashing", March 2006

Source of RFC: IETF - NON WORKING GROUP
Area Assignment: sec

Errata ID: 3507

Status: Verified
Type: Technical

Reported By: Lucas Clemente Vella
Date Reported: 2013-03-03
Verifier Name: Sean Turner
Date Verified: 2013-03-16

Section Appendix says:

     'a' * 2^25    5109A660  2E2DBC36860A0A5F  72C6388BACE3ACE6FBF062D9

It should say:

     'a' * 2^25    85EE5CAE  FACA46F856E9B45F  A621C2457C0012E64F3FDAE9

Notes:

The test vector for message 'a' * 2^25 is wrong in the RFC. This is a know error already published by the author on the page http://fastcrypto.org/umac/ (direct link: http://fastcrypto.org/umac/rfc4418.errata.txt ), but I am reporting it here because it is neither shown in Errata Search nor triggers the costumary "Errata Exist" alert on RFC's HTML view.
