Abstract
Remote authentication is the most commonly used method to determine the identity of a remote client.Secure and efficient authentication scheme has been a very important issue with the development of networking technologies. In a Generic Framework for Authentication, preserving security and privacy in distributed systems provide three factors for authentication of clients. This paper investigates a systematic approach for authenticating clients by five factors, namely RFID card, PIN, biometrics, One Time Password (OTP) and keypad ID. The conversion not only significantly improves the information assurance at low cost but also protects client privacy in distributed systems.
