Group ring based public key cryptosystems [PDF]
Journal of Discrete Mathematical Sciences and Cryptography, 2021, 2019 In this paper, we propose two cryptosystems based on group rings and existing cryptosystem. First one is Elliptic ElGamal type group ring public key cryptosystem whose security is greater than security of cryptosystems based on elliptic curves discrete logarithmic problem (ECDLP).
