Abstract

The maritime wideband communication network which extends the operation of wireless access from land to sea will significantly contribute to the maritime distress urgency safety and general communications The Worldwide Interoperability for Microwave Access WiMAX technology has been applied to establish a maritime wideband shoreside network infrastructure to achieve large capacity data backhauls However in this scenario many new security and privacy challenges are arising eg the reduced time overhead for group access authentication due to limited time window vessels passing by infostations along the shoreside In this paper a simple and reliable group authentication framework is developed for dealing with security issues in this special maritime wideband communication scenario Specifically an efficient authentication protocol for secure group communications EAPSG in maritime wideband communication network is proposed based on the Elliptic Curve DiffieHellman ECDH to overcome the weakness existing in the prevailing protocols on land ie user identity disclosure the lack of perfect forward secrecy and maninthemiddle attacks Meanwhile EAPSG can reduce the communication overhead and computational complexity by designing group access authentication procedures Compared with conventional EAPAKA protocol used in WiMAX networks on land our scheme enhances the security and provides better performance Especially the security of the proposed protocol was verified by Automated Validation of Internet Security Protocols and Applications AVISPA and detailed performance evaluations are also given The results illustrate that the proposed EAPSG outperforms other existing schemes on land in terms of the delivery cost and the number of signaling messages
