DESCRIPTION:Speaker: Michal Rybar\nhosted by Sandra Siegert\nAbstract: Mess
 age authentication is one of the basic tasks in cryptography. Even though 
 message authentication codes are around for decades\, for many of them the
 ir exact security is not known. In the talk you will see two examples of a
 lgorithms where it was worth re-visiting their proofs of security. New pro
 ofs for these constructions will be explained\, as well as new matching at
 tacks. Together\, they expose the true security of both constructions.\n\n
 =====================\nMichal Rybár is a Ph.D. candidate in the Pietrzak 
 group\, working on message authentication codes and symmetric cryptography
 . He obtained his Master's degree from the University of Bristol in the Un
 ited Kingdom\, before he joined IST in 2012.
