The first practical public key cryptosystem to be published, the Diffie-Hellman key exchange algorithm, was based on the assumption that discrete logarithms are hard to compute. T...
In this paper, we build, in a generic way, two asymmetric cryptosystems with a careful study of their security. We present first an additively homomorphic scheme which generalizes,...
— High secure cryptographic systems require large bit-length encryption keys which presents a challenge to their efficient hardware implementation especially in embedded devices...

Digital signature authentication scheme provides secure communication between two users. Digital signatures guarantee end-to-end message integrity and authentication information a...
Elliptic Curve Cryptosystems (ECC) have become popular in recent years due to their smaller key sizes than traditional public key schemes such as RSA. However the gap between the ...
