摘要
The 3PAKE(Three-Party Authenticated Key Exchange)protocol is a valuable cryptographic method that offers safe communication and permits two diverse parties to consent to a new safe meeting code using the trusted server.There have been explored numerous 3PAKE protocols earlier to create a protected meeting code between users employing the trusted server.However,existing modified 3PAKE protocols have numerous drawbacks and are incapable to provide desired secrecy against diverse attacks such as manin-the-middle,brute-force attacks,and many others in social networks.In this article,the authors proposed an improved as well as safe 3PAKE protocol based on the hash function and the symmetric encryption for the social networks.The authors utilized a well-acknowledged AVISPA tool to provide security verification of the proposed 3PAKE technique,and findings show that our proposed protocol is safer in opposition to active as well as passive attacks namely the brute-force,man-in-the-middle,parallel attack,and many more.Furthermore,compared to other similar schemes,the proposed protocol is built with a reduced computing cost as our proposed protocol consumes less time in execution and offers high secrecy in the social networks with improved accuracy.As a result,this verified scheme is more efficient as well as feasible for implementation in the social networks in comparison to previous security protocols.Although multifarious authors carried out extensive research on 3PAKE protocols to offer safe communication,still there are vital opportunities to explore and implement novel improved protocols for higher safety in the social networks and mobile commerce environment in the future in opposition to diverse active as well as passive attacks.
