Publication History

Published Online:

We present a cryptosystem which is complete for the class of probabilistic public-key cryptosystems with bounded error. Besides traditional encryption schemes such as RSA and El Gamal and probabilistic encryption of Goldwasser and Micali, this class contains also Ajtai-Dwork and NTRU cryptosystems. The latter two make errors with a small positive probability.
