A Practical Public Key Cryptosystem Provably Secure Against Adaptive Chosen Ciphertext Attack
@article{Cramer1998APP, title={A Practical Public Key Cryptosystem Provably Secure Against Adaptive Chosen Ciphertext Attack}, author={Ronald Cramer and Victor Shoup}, journal={IACR Cryptol. ePrint Arch.}, year={1998}, volume={1998}, pages={6} }
A new public key cryptosystem is proposed and analyzed. The scheme is quite practical, and is provably secure against adaptive chosen ciphertext attack under standard intractability assumptions. There appears to be no previous cryptosystem in the literature that enjoys both of these properties simultaneously.
