Cryptography Lecture 13 Hash functions Hash functions Cryptographic hash function deterministic function mapping arbitrary length inputs to a short fixedlength output Hash functions can be keyed. However computational aspects of lattices were not investigated much until the early 1980s when they were successfully employed for breaking several proposed cryptosystems among many other applications It was not until the late 1990s that lattices w 897 Special Topics in Cryptography Instructors Ran Canetti and Ron Rivest Lecture 25 PairingBased Cryptography May 5 2004 Scribe Ben Adida 1 Introduction The 64257eld of PairingBased Cryptography has exploded CS 465.
