One-time password (OTP) mechanisms are widely used to strengthen authentication processes. In time-based one-time password (TOTP) mechanisms, the client and server store common secrets. However, once the server is compromised, the client’s secrets are easy to obtain. To solve this issue, hash-chain-based second-factor authentication protocols have been proposed. However, these protocols suffer from latency in the generation of OTPs on the client side because of the hash-chain traversal. Secondly, they can generate only a limited number of OTPs as it depends on the length of the hash-chain. In this paper, we propose a second-factor authentication protocol that utilizes Physically Unclonable Functions (PUFs) to overcome these problems. In the proposed protocol, PUFs are used to store the secrets of the clients securely on the server. In case of server compromise, the attacker cannot obtain the seeds of clients’ secrets and can not generate valid OTPs to impersonate the clients. In the case of physical attacks, including side-channel attacks on the server side, our protocol has a mechanism that prevents attackers from learning the secrets of a client interacting with the server. Furthermore, our protocol does not incur any client-side delay in OTP generation.

one who has the credentials irrespective of the knowledge of the authenticity of the authentic user. Adopting a mixture and layers of different types of authentication methods can protect the system better from unauthorized users. Some of the most common second factor authentication methods adopted by financial institutions like banks are use of PIN sentry, memorable word, and OTP (One Time Password) [2-5]. Financial organizations like Barclays even uses second or third factor authentication depending on the online activity and the session keys are generated based on factors like knowing user memorable PIN, transaction amount, smart card information, physical card availability etc. using Chip Authentication Program like PIN sentry, but detail internal methods and techniques are not available in public domain due to security reasons and one such security framework for card reader is presented by [2]. In a PIN sentry approach, it reads the card details and using the secret pin, one-time 8-digit pin password is generated to authenticate.

World is going toward digitalization and cloud computing plays an important role to connect digital devices for communication with each other. Communication with authentic device and secure its illegal access is the main feature of cloud providers. With the growth of cloud technologies attackers are also finding different attack vectors to break down the cloud authentication system. Previous research illustrates that there is need to develop strong authentication technique to strengthen the trust on cloud systems. This paper demonstrated a visual cryptographic authentication technique for cloud environment. The technique is based on the SVD factorization method. SVD works effectively to create multiple shares of an image and make strong authentication algorithm on the basis of random image feature selection. Result analysis shows that SVD factorization works effectively rather than LU factorization in cloud environment.
