In this paper: In several encryption algorithms, the key exchange scheme (KES) type: Diffie-Hellman is used as a fundamental tool. In this paper, a new KES model has been proposed as an alternative contribution for...

In this paper: A new version of digital signature scheme (DSS) has been proposed in this work. This version has used a new concept of linear algebra which is called the integer matrix of Fibonacci numbers with size...

In this paper: A triple vertex (TV) and triple vertex path (TVP) graph are defined as new concepts. These concepts consider the main point of this work to modify the symmetric encryption (SE) schemes and increase th...

In this paper: An elliptic curve matrix (ECM) is created randomly based on an elliptic curve group to modify the elliptic curve-discrete logarithm (EC-DL) cryptosystems, which are elliptic Diffie-Hellman key exchang...

In this paper: In this paper, we describe a new contribution that uses the optimization problem to create a new version of the Diffie-Hellman key exchange (DHKE). The proposed version depended on the optimized discr...
