Orr Dunkelman

An active member of the research community in the fields of cryptanalysis (breaking ciphers), computer security, and privacy, Orr Dunkelman has published numerous papers analyzing the security of ciphers and cryptosystems. He is widely recognized for his work on the Advanced Encryption Standard (AES), the KASUMI block cipher that is used to protect 3G communications, and the KeeLoq block cipher that is widely deployed in remote entry systems, such as alarms.

But in today’s information-based world, where much of one’s personal information is available at the click of a mouse, is such an assumption so safe?
