This paper provides hardware-independent authentication named as Intelligent Authentication Scheme, which rectifies the design weaknesses that may be exploited by various security attacks. The Intelligent Authentication Scheme protects against various types of security attacks such as password-guessing attack, replay attack, streaming bots attack (denial of service), keylogger, screenlogger and phishing attack. Besides reducing the overall cost, it also balances both security and usability. It is a unique authentication scheme.

Kerberos is a third party and widely used authentication protocol, in which it enables computers to connect securely using a single sign-on over an insecure channel. It proves the identity of clients and encrypts all the communications between them to ensure data privacy and integrity. Typically, Kerberos composes of three communication phases to establish a secure session between any two clients. The authentication is based on a password-based scheme, in which it is a secret long-term key shared between the client and the Kerberos. Therefore, Kerberos suffers from a password-guessing attack, the main drawback of Kerberos. In this paper, we overcome this limitation by modifying the first initial phase using the virtual password and biometric data. In addition, the proposed protocol provides a strong authentication scenario against multiple types of attacks.
