Talk Title: Recent Developments in Identity Based Encryption: Latti

ces and Beyond

Talk Abstract: We present new directions for constructi

ng identity based encryption systems from hard problems on lattices. Rec

all that in an Identity Based encryption (IBE) system any string can functi

on as a public key. IBE systems imply CCA-secure encryption, searching on

encrypted data, secure signatures, and many other cryptographic primitive

s. Until recently all constructions were based on groups with a bilinear

map or on the quadratic residousity assumption. Recently, starting with
the work of Gentry, Peikert, and Vaikuntanathan, there has been some in

terest in constructing IBE systems from hard problems on lattices. In this

talk will describe a number of new IBE constructions and related primitives
from lattice problems. This is joint work with Shweta Agrawal and Xavier
Boyen.
