چکیده
In 2013, Tsai et al. cryptanalyzed Yeh et al. scheme and shown that Yeh et al., scheme is vulnerable to various cryptographic attacks and proposed an improved scheme. In this poster we will show that Tsai et al., scheme is also vulnerable to undetectable online password guessing attack, on success of the attack, the adversary can perform all major cryptographic attacks. As apart of our contribution, we have proposed an improved scheme which overcomes the defects in Tsai et al. and Yeh et al. schemes.

Cryptanalysis on 'Robust Biometrics-Based Authentication Scheme for Multi-server Environment'
Authentication plays an important role in an open network environment in order to authenticate two communication parties among each other. Authentication protocols should protect the sensitive information against a malicious adversary by providing a variety of services, such as authentication, user credentials’ privacy, user revocation and re-registration, when the smart card is lost/stolen or ...
متن کاملA secure dynamic ID based remote user authentication scheme for multi-server environment
Since the number of server providing the facilities for the user is usually more than one, the authentication protocols for multi-server environment are required for practical applications. Most of password authentication schemes for multi-server environment are based on static ID, so the adversary can use this information to trace and identify the user's requests. It is unfavorable to be appli...
متن کاملA Biometrics-based Multi-server Key Agreement Scheme on Chaotic Maps Cryptosystem
Nowadays chaos theory is widely used in cryptography. In the real world, in order to ensure secure communication, many chaotic maps-based key agreement protocols have been proposed. Most of them used a smart card on account of the inherent ability of anti-interference. Popularly, many related protocols using smart card are used for a single server environment. However, existing single server au...
متن کاملAn Efficient and Secure Multi-server Smart Card based Authentication Scheme
This paper proposes an efficient and robust multi-server authentication scheme using smart cards. Security of this scheme depends upon cryptographic one-way hash function. This scheme allows remote users to access multiple servers without any need of separately registering with each server. Also, it gets rid of the use of verification table, permits users to select and update the password secur...
متن کاملCryptanalysis and Improvement of a Biometrics-Based Multi-server Authentication with Key Agreement Scheme
1 Abstract—In 2010, Yoon et al. proposed a robust biometrics-based multi-server authentication with key agreement scheme for smart cards on elliptic curve cryptosystem. In this letter, however, we show that Yoon et al.'s scheme is vulnerable to off-line password guessing attack and propose an improved scheme to prevent the attack.
متن کاملA biometric-based Password Authentication with key Exchange Scheme using Mobile Device for Multi-Server Environment
Remote authentication for multi-server environment can help users register only once and access arbitrary services conveniently in the same registry realm. However, most of the solutions are plagued by security problems. In this paper, we point out that ‘a novel smart card and dynamic ID based remote user authentication scheme for multi-server environment’ is vulnerable to user impersonation at...
