New public-key cryptosystem algorithm based on function composition of matrix

Maxrizal, Baiq Desy Aniska Prayanti, Amri, Bambang Adiwinoto

Published Online: 16 Sep 2024DOI: 10.47974/JDMSC-1862

In this paper: Experts argue that public key cryptography systems based on commutative groups (abelian groups) are quite vulnerable to quantum algorithms attacks. For this reason, experts have developed a non-commut...

Modified public key cryptosystem based on distance and geometry area in triangles

Maxrizal, Baiq Desy Aniska Prayanti

Published Online: 29 Dec 2023DOI: 10.47974/JIM-1660

In this paper: Public key cryptosystems using commutative algebra are not safe from quantum algorithm attacks. For this reason, experts have developed non-commutative algebra applied to geometry-based public key cry...
