Query: Group ring based public key cryptosystems   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). Second is ElGamal type
group ring public key cryptosystem, which is analogous to ElGamal public key
cryptosystem but has comparatively greater security. Examples are also given
for both the proposed cryptosystems.
