Cryptanalysis of Timestamp-Based Password Authentication Schemes Using Smart Cards
"... Abstract. Password authentication is an important mechanism for remote login systems, where only authorized users can be authenticated via using their passwords and/or some similar secrets. In 1999, Yang and Shieh [14] proposed two password authentication schemes using smart cards. Their schemes are ..."

Cryptanalysis of a Timestamp-Based Password Authentication Scheme
, 2004
"... Recently, J.-J. Shen, C.-W. Lin and M.-S. Hwang (Computers & Security, Vol 22, No 7, pp 591-595, 2003) proposed a modi ed Yang-Shieh scheme to enhance security. They claimed that their modi ed scheme can withstand the forged login attack and also provide a mutual authentication method to preve ..."

to prevent the forged server attack. In this paper, we show that the Shen-Lin-Hwang scheme cannot resist the forged login attack either. The intruder is able to forge a valid forge request of a legitimate user U i and then successfully impersonate him by intercepting a login request sent by U i
A Security Enhanced Timestamp-Based Password Authentication Scheme Using Smart Cards*
, 2006
"... The intent of this letter is to propose an efficient timestamp based password authentication scheme using smart cards. We show various types of forgery attacks against Shen et al.’s timestamp-based password authentication scheme and improve their scheme to ensure robust security for the remote authe ..."

An efficient password authentication scheme for smart card,”
- International Journal of Network Security,
, 2012
"... Abstract Yang-Wang-Chang proposed an improved timestamp associated password authentication scheme based on YangShieh, who had earlier proposed timestamp-based remote authentication scheme using smart cards. In this paper, we propose an efficient password authentication scheme with smart card applyi ..."

Authentication Scheme Against Smart Card Security Breach
"... User authentication is one of the fundamental procedures to provide secure communications between user and server over an insecure public channel. Recently, Wang et. al. proposed password-based user authentication scheme based on hash function and modular exponentiation and they claimed that their s ..."

that their scheme provides strong authentication than related scheme. But in this paper, it is pointed out that their scheme suffers from off-line password guessing attack, off-line identity guessing attack, user impersonation attack, server masquerading attack, smart card stolen attack and password change attack
Remote password authentication with smart cards
- IEE Proc. computers and Digital Techniques
, 1999
"... Abstract: A remote password authentication scheme based on the Chinese remainder theorem is proposed. The scheme can verify the remote password without verification tables. In the initial phase, the password generation centre generates and assigns a password corresponding to each user. The ideas of ..."

of smart cards and the identity-based signature scheme introduced by Shamir are employed in this phase. Each user possesses a smart card for later login and authentication. In the login phase, the user submits the identity and password associated with the smart card. In the authentication phase, the system
Weaknesses of an Improvement Authentication Scheme using Smart Cards
"... Abstract: Recently, Sood-Sarje-Singh proposed an improvement to Liou et al.’s dynamic ID-based remote user authentication scheme using smart cards to prevent impersonation attack, malicious user attack, off-line password guessing attack, and man-in-the-middle attack. However, we demonstrate that Soo ..."

Improvement of the ElGamal Based Remote Authentication Scheme Using Smart Cards
"... Nowadays, we can easily obtain variety of services through networks. But due to the open environment, networks are vulnerable to many security threats. The remote user authentication scheme is one of the most widely used mechanisms for servers to authorize users to access the services. In 2009, Rama ..."

solution for remote access. It lacks key agreement mechanism and users cannot choose or update passwords freely. Moreover, their scheme cannot resist the stolen-verifier attack, off-line guessing attack, impersonation attack and smart-card-loss-attack. We propose an improved scheme to remedy the drawbacks
An Improvement of Liou et al.’s Authentication Scheme using Smart Cards
"... In 2004, Das et al. proposed a dynamic identity based remote user authentication scheme. This scheme allows the users to choose and change their passwords freely and the server does not maintain any verification table. Das et al. claimed that their scheme is secure against stolen verifier attack, re ..."

A Novel Smart Card Authentication Scheme using Image Encryption
"... From the user point of view, security and efficiency are the two main factors for any authentication scheme. However, most of the smart card authentication schemes are vulnerable to one or the other possible attack. In this paper, highly secured smart card authentication scheme is proposed using ima ..."
