Hirsch Steklov Institute of Mathematics, 27 Fontanka, 191023 St. Petersburg, Russia hirsch@pdmi.ras.ru Konstantin Pervyshev Dept. of Computer Science and Engineering, University of California, 9500 Gilman Drive, La Jolla, CA 92093-0404, U.S.A. pervyshev@gmail.com 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. [ Fulltext-pdf (136 KB)] for subscribers only. |
