A Secure Three-Factor Authentication Protocol for E-Governance System Based on Multiserver Environments

In electronic governance (e-governance) system, citizens can access government services such as transportation, licensing and immigration remotely over the Internet. With development of information communication technology, usage e-governance system has been increased. To efficiently provide with various services, multi-server environments be applied to system. However, messages inserted, deleted, modified by a malicious adversary since these are transmitted through public channel. Therefore, many researchers have suggested mutual authentication protocols for secure in environments. 2020, Sudhakar et al. proposed smart card based lightweight protocol We analyze al.’s propose on we disclosure that their is not resistant stolen, insider, man-in-the-middle, user impersonation, session key attacks. Moreover, does authentication. improve security problems, suggest three-factor prove our protocol’s using informal analysis, Burrows-Abadi-Needham (BAN) logic, Real-or-Random (ROR) model. also simulate utilizing Automated Validation Internet Security Protocols Applications (AVISPA) tool.We estimate functionalities, computation costs, overheads compared existing related protocols. Consequently, demonstrate suitable
