Password authentication scheme based on smart card and QR code

As a hopeful computing paradigm, cloud services are obtainable to end users based on pay-as-you-go service. Security is represented one of the vital issues for extended adoption computing, with object accessing several service providers, applications, and by using anonymity features authenticate user. We present good authentication scheme quick response (QR) code smart card. Furthermore, our proposed has crucial merits such as key management, mutual authentication, one-time password, user anonymity, freely chosen secure password changes, revocation QR code. The security depends crypto-hash function, QR-code validation, Moreover, we view that can resist numerous malicious attacks more appropriate practical applications than other previous works. proved strong burrows-abadi-needham (BAN) logic analysis. results compared related work.
