Analysis of Fuzzy Based Provably Secure Multi-Server Authentication Remote User Authentication Scheme
Author:
Abstract: In past people used to send the messages in plain text over the public channel. However, this protocol susceptible to various attacks like anyone can read the message, no proper authentication of sender and receiver, tampering, etc. Indeed, Remote User Authentication (RUA) is a technique is the key to solution of all these problems. RUA is scheme in which any remote user can not only authenticate but also transfer the messages over insecure medium to server even though the extraneous physical distance between them. With advancement in technology, the system moved to multi server in which user can connect to the any server and have the secure established session over public channel. Recently, in IEEE Access, Barman et al. proposed the multi-server remote user authentication scheme using the notion of fuzzy commitment and claimed to secure against various attack. However, in this paper we prove that the scheme due to Barman et al. is failed to provide the countermeasure against user anonymity, server anonymity and perfect forward secrecy attack.
