Abstract

Abstract:In order to efficiently eliminate the security shortcomings of the dynamic ID based remote user authentication scheme using smart cards (short for XJWM scheme) proposed by Xu et al.,a new multi server and multi factor anonymous remote authenticated key agreement protocol was presented,based on Diffie Hellman key agreement algorithm and biometrical authentication technology.The new protocol can not only overcome the security flaws of XJWM scheme,but also add smart card’s password and bio information authentication for the cardholder to avoid the smart card stolen attack.The security of the new protocol was proved by the improved BAN logic and the result showed that the new scheme can ensure the correctness of key agreement,key confidentiality,key freshness and mutual authentication.The security and performance analysis demonstrated that the proposed protocol provides better security without increasing too much computation overhead.

In 2007, Liao-Wang proposed a dynamic ID-based remote user authentication scheme for multi-server environment using smart cards.However, Hsiang-Shih demonstrated that Liao-Wang's scheme has security flaws.Moreover, Hsiang-Shih proposed an improvement scheme which resolves the security flaws of Liao-Wang scheme.In this paper, we propose an enhanced remote user authentication scheme which maintains the merits of Hsiang-Shih's scheme.Performance evaluation demonstrated the efficiency of the proposed scheme over related works.Security analysis proved that the proposed scheme is secure against known attacks.

A Secure Two-Factor Remote User Authentication and Session Key Agreement Scheme

Preeti Chandrakar, Hari Om

In this article, the authors have proposed a secure two-factor remote user authentication and session key agreement protocol. As they have shown in the presented scheme, is precise and secure according to both formal and informal security analysis. For formal security analysis, they have applied BAN (Burrows-Abadi-Needham) logic which certifies that the presented scheme provides the amenity of mutual authentication and session key agreement safely. The informal security verification has shown that the proposed scheme is more vigorous against various sort of cruel threats. Moreover, the authors have simulated the presented scheme using broadly accepted AVISPA tool, whose simulation results make sure that the protocol is not dangerous from active and passive attacks together with replay and man-in-the-middle attacks. In addition, the performance evaluation and the security comparison have revealed that the presented scheme gives strong security as well as better complexity in the context of smart card memory requirement, communication cost and computation cost.

Provable analysis and improvement of smart card–based anonymous authentication protocols

Saeed Banaeian Far, Mahdi R. Alagheband

Summary Nowadays, authentication protocols are essential for secure communications specially for roaming networks, distributed computer networks, and remote wireless communication. The numerous users in these networks rise vulnerabilities. Thus, privacy‐preserving methods have to be run to provide more reliable services and sustain privacy. Anonymous authentication is a method to remotely authenticate users with no revelation about their identity. In this paper, we analyze 2 smart card–based protocols that the user's identity is anonymous. However, we represent that they are vulnerable to privileged insider attack. It means that the servers can compromise the users' identity for breaking their privacy. Also, we highlight that the Wen et al protocol has flaws in both stolen smart card and stolen server attacks and the Odelu et al protocol is traceable. Then, we propose 2 modified anonymous authentication protocols. Finally, we analyze our improved protocols with both heuristic and formal methods.

Cryptanalysis of Two Dynamic ID-Based Remote User Authentication Schemes for Preserving User Privacy

Jian-Wen Peng, Wen-Bing Horng, Ying-Ching Chiu +1 more

Remote user authentication is an essential part in electronic commerce to identify legitimate users over the Internet. However, how to protect user privacy in the authentication has become an important issue recently. Therefore, many secure authentication schemes with smart cards have been proposed. In this paper, we will analyze the security weaknesses of two recently proposed authentication schemes for preserving user privacy. First, Chang et al. (2011) proposed a robust and efficient remote user authentication scheme to provide user anonymity. However, this scheme fails to protect user privacy in terms of anonymity and traceability. In addition, it is vulnerable to the server counterfeit attack and it does not provide perfect forward secrecy for session keys. Furthermore, if the smart card is lost, it will suffer from the offline password guessing attack as well as the user impersonation attack. Second, Wen and Li (2012) recently presented an improved dynamic ID-based authentication scheme with key agreement. However, this scheme is vulnerable to traceability. In addition, it does not support perfect forward secrecy for session keys. Furthermore, the insecure offline password change phase and online secret renewal phase will result in the denial of service attack.

Cryptanalysis and security enhancement of a robust two‐factor authentication and key agreement protocol

Qi Xie, Na Dong, Duncan S. Wong +1 more

Summary Two‐factor user authentication scheme allows a user to use a smart card and a password to achieve mutual authentication and establish a session key between a server and a user. In 2012, Chen et al . showed that the scheme of Sood et al . does not achieve mutual authentication and is vulnerable to off‐line password guessing and smart card stolen attacks. They also found that another scheme proposed by Song is vulnerable to similar off‐line password guessing and smart card stolen attacks. They further proposed an improved scheme. In this paper, we first show that the improved scheme of Chen et al . still suffers from off‐line password guessing and smart card stolen attacks, does not support perfect forward secrecy, and lacks the fairness of session key establishment. We then propose a new security‐enhanced scheme and show its security and authentication using the formal verification tool ProVerif, which is based on applied pi calculus.

Cryptanalysis Of Dynamic ID Based Remote User Authentication Scheme With Key Agreement.

Sonam Devgan Kaul, Amit K. Awasthi

Summary. In 2012, Wen and Li proposed a secure and robust dynamic identity based remote user au-thentication scheme with key agreement using smart cards. They claimed that their scheme is efficient and secure. But in this paper, we demonstrate that their scheme is completely insecure and vulnerable to various known attacks like offline and online password guessing attack, impersonation attack, server mas-querading attack, denial of service attack and an insider attack. Also we point out that there are loopholes in password change phase and online secret renew phase which leads to the desynchronization between user and the server and even the legitimate user is rejected by the server. In addition, an adversary can easily generate the common session key of further transmission between user and the server. Thus the entire system collapses and authors claims are proven to be wrong and their scheme will not be secure and efficient for practical purpose.
