IAMS framework: a new framework for acceptable user experiences for integrating physical and virtual identity access management systems
The modern world is populated with so many virtual and physical Identity Access Management Systems (IAMSs) that individuals are required to maintain numerous passwords and login credentials. The tedious task of remembering multiple login credentials can be minimised through the utilisation of an innovative approach of single sign-in mechanisms. During recent times, several systems have been developed to provide physical and virtual identity management systems; however, most have not been very successful. Many of the available systems do not provide the feature of virtual access on mobile devices via the internet; this proves to be a limiting factor in the usage of the systems. Physical spaces, such as offices and government entities, are also favourable places for the deployment of interoperable physical and virtual identity management systems, although this area has only been explored to a minimal level. Alongside increasing the level of awareness for the need to deploy interoperable physical and virtual identity management systems, this paper addresses the immediate need to establish clear standards and guidelines for successful integration of the two medium
Anonymous Authentication Against Man-In-The-Middle Attack
Evolving enterprise in application and data with flexible and scalable infrastructure in cloud services could improve efficiency and productivity of a business operation. Cloud services also offer resource sharing, data storage and application platform as on-demand services that could reduce the operational expenditure. Nevertheless, increasing usage and accessibility to the cloud services require strong security control to preserve userâs privacy and data integrity due to network communication vulnerabilities. There are many possible attacks that could cause security breach and abuse the userâs identity, leading to illegal access to the server. Man-inthe-middle attack is one of the attacks that can intercept communication between users and collect all usersâ information. The attacker can misuse the information and act as a legal user to gain access to the system. It is a big challenge to preserve userâs privacy and provide protection from malicious attack. This paper proposes anonymous authentication scheme to preserve userâs privacy and provide protection to such possible attacks. The proposed scheme also provides secure mutual authentication, anonymity, session key establishment and non-dependency with the third party. The proposed scheme uses password-based authentication as an authentication method with anonymity feature to preserve userâs privacy. Experiment was conducted to test and validate the proposed scheme with man-in-the-middle attack. The result of the experiment shows that the proposed scheme is able to provide the privacy to mitigate and successfully preserve the userâs identity from the attack
Bio-AKA: An efficient fingerprint based two factor user authentication and key agreement scheme
The fingerprint has long been used as one of the most important biological features in the field of biometrics. It is person-specific and remain identical though out oneâs lifetime. Physically uncloneable functions (PUFs) have been used in authentication protocols due to the unique physical feature of it. In this paper, we take full advantage of the inherent security features of userâs fingerprint biometrics and PUFs to design a new user authentication and key agreement scheme, namely Bio-AKA, which meets the desired security characteristics. To protect the privacy and strengthen the security of biometric data and to improve the robustness of the proposed scheme, the fuzzy extractor is employed. The scheme proposed in the paper can protect userâs anonymity without the use of password and allow mutual authentication with key agreement. The experimental results show superior robustness and the simplicity of our proposed scheme has been validated via our performance and security analysis. The scheme can be an ideal candidate for real life applications that requires remote user authentication
On Security Analysis of Recent Password Authentication and Key Agreement Schemes Based on Elliptic Curve Cryptography
Secure and efficient mutual authentication and key agreement schemes form the basis for any robust network communication system. Elliptic Curve Cryptography (ECC) has emerged as one of the most successful Public Key Cryptosystem that efficiently meets all the security challenges. Comparison of ECC with other Public Key Cryptosystems (RSA, Rabin, ElGamal) shows that it provides equal level of security for a far smaller bit size, thereby substantially reducing the processing overhead. This makes it suitable for constrained environments like wireless networks and mobile devices as well as for security sensitive applications like electronic banking, financial transactions and smart grids. With the successful implementation of ECC in security applications (e-passports, e-IDs, embedded systems), it is getting widely commercialized. ECC is simple and faster and is therefore emerging as an attractive alternative for providing security in lightweight device, which contributes to its popularity in the present scenario. In this paper, we have analyzed some of the recent password based authentication and key agreement schemes using ECC for various environments. Furthermore, we have carried out security, functionality and performance comparisons of these schemes and found that they are unable to satisfy their claimed security goals
