Factoring and Discrete Logarithm using IBC
In 1984, Shamir proposed the concept of the ID-based cryptosystem (IBC). Instead of generating and publishing a public key for each user, the ID-based scheme permits each user to choose his name or network address as his public key. This is advantageous to public-key cryptosystems because the public-key verification is so easy and direct. In such a way, a large public key file is not required. ...
متن کاملA Factoring and Discrete Logarithm based Cryptosystem
This paper introduces a new public key cryptosystem based on two hard problems : the cube root extraction modulo a composite moduli (which is equivalent to the factorisation of the moduli) and the discrete logarithm problem. These two hard problems are combined during the key generation, encryption and decryption phases. By combining the IFP and the DLP we introduce a secure and efficient publi...
متن کاملAn Efficient Signature Scheme based on Factoring and Discrete Logarithm
This paper proposes a new signature scheme based on two hard problems : the cube root extraction modulo a composite moduli (which is equivalent to the factorisation of the moduli, IFP) and the discrete logarithm problem(DLP). By combining these two cryptographic assumptions, we introduce an efficient and strongly secure signature scheme. We show that if an adversary can break the new scheme wit...

متن کاملA New Digital Signature Scheme Based on Integer Factoring and Discrete Logarithm Problem
A new idea for digital signature scheme is suggested. The suggested scheme employs a composite modulus that is a product of two distinct prime numbers. There is a similarity with the most widely used digital signature schemes such as RSA regarding the algebraic background. The new scheme uses operations in prime integer order, a characteristic that is similar to Digital Signature Standard ( DSS...
