My talk will mainly be on new developments in generalized identity-based cryptography. Identity-based cryptography is relatively new technology, less than a decade old, in which a message can be encrypted using any string as a public key. More generally, we could imagine encrypting a message under a policy which specifies under what conditions someone is allowed to read it. I will give a summary and some specific examples of my work in this area. Additionally, I will outline some of my work on fast and secure cryptographic implementations
