A1 Singh, Vijay T1 ADVANCE REMOTE USER AUTHENTICATION SCHEME USING SMART CARD JF Telecommunications and Radio Engineering JO TRE YR 2019 FD 2019-07-18 VO 78 IS 11 SP 957 OP 971 AB In 2016, Kaul and Awasthi proposed security enhancement of an improved remote user authentication scheme with key agreement and they proclaimed that their scheme ensures secure communication on an insecure channel and they also proposed that their scheme is secure against active and passive attacks. But in this paper, we demonstrate that their proposed scheme is completely insecure against malicious user attack, insider attack and also that an arbitrary user can easily reregister him, if he has certain parameters of Kaul et al. proposed scheme. Thus collapses the entire security of the system as well as user's data and author claims are proven to be incorrect.
Hence to cure the identified security flaws and to ensure the communication through an insecure channel, we proposed a better secure and efficient authentication protocol mechanism and also we have added some necessary phase required in authentication.
