A Practical Public Key Cryptosystem Provably Secure against Adaptive Chosen Ciphertext Attack

Ronald Cramer and Victor Shoup

Abstract: A new public key cryptosystem is presented that is provably secure against adaptive chosen ciphertext attack. The scheme is quite practical, and the proof of security relies only on standard intractability assumptions.

Keywords: public key encryption, adaptive chosen ciphertext attack.
