Colloquium WHAT: Jean-Jacques Quisquater (Universite Catholique de Louvain) "Secure Physical Identity" WHEN: Monday, April 26, 2004, 4:00–5:00 PM EST WHERE: Bartos Theatre, MIT Media Lab (E15) SUMMARY: Identification—naming for sure a person or an object—is a very important question and is very often solved by the proof of the knowledge of something (passwords, ...), by the possession of something (card, ...), and/or by the determination of some unique (biological) charateristics. The security of the process itself (initialization, protocols of interrogation, revocation if any) is very important, and cryptography is often useful to improve the used protocols. During the first part of the talk, we will speak about cryptography and the physical hypotheses needed to meet the requirements of security. Some examples of cryptography protocols using only physical objects will be described. The second part will be devoted to recent physical attacks obtained by measurements or by active influence on the protocols or objects. The main context is smart cards. Finally we will show how a direction of research where a more important part is devoted to physics is a possible promise of more security.
