There are several candidate semantically secure encryption schemes, yet in many applications non-malleability of encryptions is crucial. We show how to transform any semantically s...
We present a scheme to protect mobile code from malicious hosts. We propose a transformation scheme that changes the semantics of a program using pseudorandom I/O scrambling, cond...
Broadcast encryption schemes allow a message sender to broadcast an encrypted data so that only legitimate receivers decrypt it. Because of the intrinsic nature of one-to-many comm...
In this paper we propose a new joint encryption and lossless compression technique designed for large images 1 . The proposed technique takes advantage of the Mojette transform pr...

Abstract. We first propose the notion of universally anonymizable publickey encryption. Suppose that we have the encrypted data made with the same security parameter, and that the...
