Abstract
In this paper, we analyze key agreement algorithms based on co-cyclic Jacket matrices, and propose key agreement algorithms based on co-cyclic Hadamard matrices to fix the problem. The performance of our proposal is better than conventional one's and the construction of the matrices is very simple. Also time complexity of our proposal is proportional to the factor that determinees the size of the matrix, and the length of the key. So our proposal is fast and will be useful for the communcations of two or three users, especially for those have low computing power.
