NUMERICAL METHODS FOR PARTIAL DIFFERENTIAL EQUATIONS, cilt.37, sa.2, ss.1112-1119, 2021 (SCI-Expanded)
The key agreement scheme is an important part of the cryptography theory. The first study in this field belongs to Diffie-Hellman and Merkle. We present a new key agreement scheme using a group action of special orthogonal group of2 x 2matrices with real entries on the complex projective line.
