Improved cryptanalysis of a ElGamal Cryptosystem Based on Matrices Over Group Rings
ElGamal cryptosystem has emerged as one of the most important construction in Public Key Cryptography (PKC) since Diffie-Hellman key exchange protocol was proposed. However, public key schemes which are based on number theoretic problems such as discrete logarithm problem (DLP) are at risk because o...
