Key Agreement Protocol Using Elliptic Curve Matrix Power Function

* Work is partially supported by the Lithuanian State Science and Studies Foundation.

The key agreement protocol (KAP) using elliptic curve matrix power function is presented. This function pretends be a one-way function since its inversion is related with bilinear equation solution over elliptic curve group. The matrix of elliptic curve points is multiplied from left and right by two matrices with entries in Zn. Some preliminary security considerations are presented.
