چکیده

An efficient variant of RSA cryptosystem was proposed by Cesar [2]. He called it Rprime RSA. The Rprime RSA is a combination of Mprime RSA [3] and Rebalanced RSA [9, 1]. Although the decryption speed of Rprime RSA is 27 times faster than the standard RSA and 8 times faster than the QC RSA [6] in theoretically, yet due to the large encryption exponent, the encryption process becomes slower than the standard RSA. In this paper we tried to improve the efficiency of encryption process with less compromising with the decryption speed.

An efficient variant of the RSA cryptosystem

We describe an efficient combination of two variants of the RSA cryptosystem (MPrime and Rebalanced RSA) analyzed by Boneh and Shacham [Boneh and Shacham 2002]. For 2048-bit moduli, the resulting decryption process is about 8 times faster than that presented by Quisquater and Couvreur [Quisquater and Couvreur 1982] and about 27 times faster than the original cryptosystem. Resumo. Descrevemos um...

Short-Exponent RSA

In some applications, a short private exponent d is chosen to improve the decryption or signing process for RSA public key cryptosystem. However, in a typical RSA, if the private exponent d is selected first, the public exponent e should be of the same order of magnitude as φ(N). Sun et al. devised three RSA variants using unbalanced prime factors p and q to lower the computational cost. Unfort...

An Efficient RSA Cryptosystem with BM-PRIME Method

Received Oct 5 th , 2012 Accepted Oct 30 th , 2012 Using more than two factors in the modulus of the RSA cryptosystem has the arithmetic advantage that the private key computation can be speeded up by CRT. With this idea, we present an efficient combination of two variants of RSA cryptosystem (Batch and Mprime RSA) which makes the decryption process faster than the existing variants. It can not...

On 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.
