Abstract: In the past decade, pairing-based schemes have been proposed extensively for the cryptographic primitives including key agreement. However, recently researchers have shown an increased interest in Pairing-Free cryptography because of high computational cost of Bilinear Pairings. In this study, we could propose a new two-party pairing-free identity-based authenticated key agreement protocol over elliptic curve based algebraic groups. We could show that beside of supporting security requirements of key agreement protocols, our proposed protocol could overcome to the inherent problem of identity-based cryptosystems named key escrow. In addition, performance of our proposed protocol is improved from complexity of computation perspective in compare with related works.
