Improved security analysis of OMAC
Mridul Nandi
Abstract
We present an improved security analysis of OMAC, the construction
is widely used as a candidate of MAC or Pseudo Random Function (or
PRF). In this direction, the first result was given in Crypto-05
where an improved security analysis of CBC (for fixed length or for
arbitrary length prefix-free messages) had provided. Followed by
this work, improved bounds for XCBC, TMAC and PMAC were found. The
improved bounds are of the form
