Abstract

In [1], a key agreement protocol between two users, based on the co-cyclic Jacket matrix, was proposed. We propose an improved version of that, based on the same center weighted Jacket matrix but at the point of view that it is a symmetric matrix as well as a co-cyclic matrix. Our new proposal has the same level of the performance of the protocol in [1], and can be used among three users.
