Abstract: Password and Smart card are the authentication factors to access significant information from remote servers. Authentication schemes based on RSA which are studied intensively that are utilized in most of the telecare medical systems. Latest RSA based remote beneficiary validation scheme which does not resist against certain attacks, not satisfy functional properties and consume more computations. The existing previous schemes still have less functional strengths. However, these schemes cannot be efficient by means of performance which is measured in terms of computation and communication. The improvised scheme using smart card and hash functions remove security short comings and reduce the communication, computational cost. We compare the proposed scheme with the other current schemes, our scheme has less computational, communication cost, security attacks than other schemes and prove that it efficient one.
