Several potential security risks arise while protecting data and providing access control over the data. Due to the broadcast nature of the wireless channels, wireless networks are often vulnerable to various possible known attacks. Therefore, designing a secure and efficient authentication scheme in the global mobility network (GLOMONET) environ- ment becomes a challenging task to the researchers. In recent years, several user authentication schemes for roaming services in GLOMONET have been proposed. However, most of them are either vulnerable to various known attacks or they are inef- ficient. Most recently, Zhao et al. proposed an anonymous authentication scheme for roaming service in GLOMONET (Zhao et al. in Wireless Personal Communications 78:247–269, 2014) and they claimed that their scheme can withstand all possible known & Vanga Odelu odelu.vanga@gmail.com; odelu.phd@maths.iitkgp.ernet.in Soumya Banerjee soumyaBanerjee@outlook.in Ashok Kumar Das iitkgp.akdas@gmail.com; ashok.das@iiit.ac.in Samiran Chattopadhyay samirancju@gmail.com Saru Kumari saryusiirohi@gmail.com Xiong Li lixiongzhq@163.com Adrijit Goswami goswami@maths.iitkgp.ernet.in 1 Department of Mathematics, Indian Institute of Technology, Kharagpur 721 302, India 2 Department of Computer Science and Engineering, Indian Institute of Information Technology, Chittoor, Sri City, Andhra Pradesh 517 588, India 123 Wireless Pers Commun (2017) 96:2351–2387 DOI 10.1007/s11277-017-4302-4
