With the increase in the number of e-services, there is a sharp increase in online financial transactions these days. These services require a strong authentication scheme to validate the users of these services and allow access to the resources for strong security. Since two-factor authentication ensures the required security strength, various organizations employ biometric-based or Smart Card or Cryptographic Token-based methods to ensure the safety of user accounts. But most of these methods require a verifier table for validating users at a server. This poses a security threat of stolen-verifier attack. To address this issue, there is a strong need for authentication schemes for e-services that do not require a verifier table at the server. Therefore, this paper proposes the design of an authentication scheme for e-services which should be resistant to various attacks including a stolen verifier attack. The paper will also discuss: 1) The proposed scheme analyzed for security provided against the known authentication attacks 2) The concept implementation of the proposed scheme.
