Abstract
The fast development of mobile networks and compact mobile devices bring attention to the users for wireless mobile communication. But providing security and protecting the privacy of users are the main challenges of wireless mobile communication. Recently, Authenticated Key Agreement protocols are used for secure and reliable communication in wireless mobile communication. However, the User-to-User Mutual Authentication and Key Agreement scheme is based on bilinear pairings, which involves relatively high computation cost when compared to elliptic curve scalar point multiplication. Hence, in this paper, we propose a Pairing-Free Identity-Based Mutual Authentication and Key Agreement protocol for wireless mobile communications. It consists of the following phases: Setup and Key generation, Mobility Management Entity authentication and Proxy Signature generation, Proxy Signature verification and User-to-User authentication. Experimental results show that Pairing-Free Identity-Based Mutual Authentication and Key Agreement attains significantly less computational and communication cost when compared to User-to-User Mutual Authentication and Key Agreement scheme.
Highlights
Wireless device-to-device communication has been used in many recent applications such as mobile social networks
In Key generation phase, the public and private key of UEA is computed by PKG as follows: Measurement and Control 52(7-8) SA = ða + DAÞ2:ðDA + H1ðTA, RAÞÞÀ1
The mutual authentication is performed between the users of different cells by varying the number of user cells from 3 to 18
Summary
Wireless device-to-device communication has been used in many recent applications such as mobile social networks. In User-to-User Mutual Authentication and Key Agreement (UUMAKA),[6] the relative computation cost of the bilinear pairing is significantly higher than that of elliptic curve scalar point multiplication.[4] a pairing-free AKA protocol is necessary, which uses both ECC and IBC for two-party communication. In this paper, Pairing-Free Identity-Based Mutual Authentication and Key Agreement (PIMAKA) scheme for WMN is proposed
