In this paper the authors propose an efficient and secure authenticated key agreement protocol based on DLP (Discrete Logarithm Problem). The main purpose of this paper is to achieve most of goals of key agreement. They show that their protocol meets the security attributes and strong against most of potential attacks. They try in their new protocol to provide the authentication between users with maintain the number of sending message minimum as possible and by using only one operation of multiplication, subtraction and exponentiation. They use the mathematica 9 program to implement the new proposed system.
