Abstract: Key agreement protocol(s) is one of the important factors for establishing communication between two parties. Recent works support the use of pairing free certificateless authenticated key agreement protocol(s) and becomes a promising base in a energy-famished WSN. Certificateless concept provides an authentication by eliminating the need of certificates of traditional public key cryptography and key escrow problem of identity based cryptography (IBC). This paper presents a non-interactive Certificateless two-party authenticated key agreement (NI-CTAKA) protocol for WSN. NI-CTAKA is pairing-free as well as reduces number of scalar point multiplications. NI-CTAKA has been implemented on MICAz platform using TinyOS-2.1.2 and RELIC-0.3.3 cryptographic library and the results has been analysed for storage-cost, running time and energy consumption. Further, NI-CTAKA is proven to be secure in the security model presented by Lipold et al. extended Canetti-Krawczyk (eCK) model. The comparative analysis proves that the proposed protocol is more efficient than the existing protocols.

Keywords: certificateless key agreement; CTAKA; pairing-free; WSNs; wireless sensor networks; authenticated key agreement protocols; cryptography; network security; storage cost; running time; energy consumption.
