Recently, there is still vulnerability of attack, such as location tracking attack, replay attack, spoofing attack etc for all that is much research for Mobile RFID authentication. This paper designed method of making one time random number in DB server side unlike previously researched protocols, and it protects RFID communication from location tracking, replay attack and spoofing attack.

The RFID(Radio-Frequency IDentification) systems have many security problem such as eavesdropping, a replay attack, location tracking and DoS(Denial of Service) attacks. Because RFID systems use radio-frequency. So research are being made to solve the problem of RFID systems, one of which is AES algorithm. This paper presents an authentication protocol using AES and one-time random number to secure other attacks like eavesdropping, a replay attack, location tracking, In addtion, RSMAP uses OTP(One-Time Pad) in order to safely transmit.

Internet banking, electronic financial services and internet telephony service can be available on smart phone recently. In this case, more robust authentication mechanisms should be provided for enhancing security on it. In this study, a facial biometric ID based one-time password generation mechanism is designed and implemented for enhancing user authentication on smart phone. After capturing a facial biometric data using camera module on smart phone, it is sent to server to generate one-time biometric ID. Finally one-time password will be generated by client module after receiving the one time biometric ID based challenge token from the server. Using proposed biometric ID based one-time password mechanism, it is possible for us to provide more secure user authentication service on smart phone for SIP protocol.
