Quaternion public key cryptosystems
Maheswara Rao Valluri, Shailendra Vikash Narayan · 2016
In this paper, quaternion key exchange protocol and quaternion public key encryption scheme are proposed. The security of proposals relies on hardness of the hidden quaternion conjugacy search problem, that is, difficulty of solving the simultaneous quaternion discrete logarithmic problem and quaternion conjugacy search problem over quaternion rings modulo prime, p. Also, the performance and the security related issues of the proposals have been discussed.
