Abstract

We present a new variant of the Cramer-Shoup leakage-resilient public key encryption. The proposed scheme is more computational efficient than the original Cramer-Shoup leakage-resilient public key encryption scheme. It enjoys a shorter (public/secret) key length, and a higher relative leakage ratio. The new scheme is proved semantically secure against adaptive chosen cipher text attack in the standard model under the decisional Diffie-Hellman assumption.
