چکیده    Due to the importance of key in providing secure communication,various key agreement protocols have been proposed in the recent years. the latest generation of public key cryptosystems (pkc) called certificateless pkc played an important role in the transformation of key agreement protocols. in this scientific area,several key agreement protocols have been proposed based on bilinear pairings. however,pairing operation is known as an expensive cryptographic function. hence,utilization of pairing operation in the mentioned works made them complex from overall computational cost perspective. in order to decrease the computational cost of key agreement protocols,several certificateless key agreement protocols have been proposed by the use of operations over elliptic curve based algebraic groups instead of using bilinear pairings. in this paper,we propose a pairing-free certificateless two-party key agreement protocol. our results indicate that our secure protocol is significantly more lightweight than existing related works. © 2015 penerbit utm press. all rights reserved.
