A New Public Key Cryptosystem Based on Edwards Curves

Maher Boudabra and Abderrahmane Nitaj

Abstract: The elliptic curve cryptography plays a central role in various cryptographic schemes and protocols. For efficiency reasons, Edwards curves and twisted Edwards curves have been introduced. In this paper, we study the properties of twisted Edwards curves on the ring $\mathbb{Z}/n\mathbb{Z}$ where $n=p^rq^s$ is a prime power RSA modulus and propose a new scheme and study its efficiency and security.
