متن کاملA New Public-Key Cryptosystem
It is striking to observe that two decades after the discovery of public-key cryptography, the cryptographer’s toolbox contains only a dozen of asymmetric encryption schemes. This rarity and the fact that today’s most popular schemes had so far defied all complexity classification a.ttempts strongly motivates the design of new asymmetric cryptosystems. Interestingly, the crypt,ographic communit...
متن کاملA Matrix Public Key Cryptosystem
We discuss a matrix public key cryptosystem and its numerical implementation.
متن کاملA Complete Public-Key Cryptosystem
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, this class contains probabilistic encryption of Goldwasser-Micali as well as Ajtai-Dwork and NTRU cryptosystems. The latter two are known to make errors with some small positive probability. To our best knowledge...
متن کاملOn DRSA Public Key Cryptosystem
The standard RSA cryptosystem is not semantically secure. Pointcheviel proposed a variant of RSA cryptosystem with the property of semantic security by introducing a new problem known as DRSA problem. He called it DRSA scheme. In this paper, we underlined a shortcoming of that scheme and proposed an alternative DRSA public key cryptosystem.
