New Tools in Cryptography |
|
|
During the past five years we have seen a wealth of new cryptographic
constructions based on an algebraic tool called "pairings." These
constructions give new key management mechanisms that are often simpler than
what is possible with traditional cryptography. They also lead to public-key
cryptographic primitives better suited for bandwidth constrained
environments. This talk will survey some of these new constructions and pose
a few open problems in this area. More specifically, we will present a
recent broadcast encryption system and a short digital signature. The talk
will be self contained. |
