• Support for automatic revocation and prematurely revocation.
• Flexible authentication for time-based digital services.

With the rapid development of the Internet of Things (IoT), IoT security has become more and more important. A large number of IoT tasks use digital signatures to ensure authenticity, integrity, and non-repudiation. However, verifying ...

The study of chaotic constructions and their associated cryptographic frameworks has sparked a lot of research interest in recent years. Latest advances in wireless technology and the proliferating limitations posed by open communication channels, ...$$

Mobile cloud computing (MCC) is an emerging computing model with the growing demands of mobile devices by services diversity using mobile cloud technology. Authentication plays a fundamental role between the smart portable devices ...

The password-based authentication mechanism is considered as the oldest and the most used method. It is easy to implement, and it does not require any particular configuration or devices. Yet, this solution does not ensure a high level of security ...

The increasing attacks against Internet of Things (IoT) systems are a determining factor to focus attention on IoT security. The use of Smart Cards (SCs) to protect these systems is pertinent, as they are resistant to physical attacks, portable, ...

This paper describes a new mobile authentication method which is based on an Open ID Connect standard and subscriber identity module card. The proposed solution enables users to access websites, services and applications without the need to remember ...

We propose two new authentication schemes for the cloud that support private attribute-based authentication services. The basic scheme is non-anonymous attribute-based authentication scheme. The extended scheme of the basic scheme is fully anonymous ...

A document can carry a tamper-proof history of its modifications.This history can be used to check constraints on that documents lifecycle.An implementation shows that manipulating this history incurs light overhead. Artifact-centric workflows describe ...

Due to the open environment in which hierarchical wireless sensor networks (HWSNs) are typically deployed, it is important to authenticate transmitted data. In recent years, a number of user authentication schemes with smart card for HWSNs have been ...

In order to provide secure remote access control, a robust and efficient authentication protocol should achieve mutual authentication and session key agreement between clients and the server over public channels. Recently, Wang et al. proposed a ...

The Session Initiation Protocol (SIP) is a signaling protocol widely applied in the world of multimedia communication. Numerous SIP authenticated key agreement schemes have been proposed with the purpose of ensuring security communication. Farash ...

Recently, numerous extended chaotic map-based password authentication schemes that employ smart card technology were proposed for Telecare Medical Information Systems (TMISs). In 2015, Lu et al. used Li et al.'s scheme as a basis to propose a password ...

In the last few years several practitioners have proposed different strategies for implementing Attribute-based credentials ABCs on smart cards. ABCs allow citizens to prove certain properties about themselves without necessarily revealing their full ...

Critical applications in wireless sensor network (WSN) are real-time based applications. Therefore, users are generally interested in accessing real-time information. This is possible, if the users (called the external parties) are allowed to access the ...

The Telecare Medicine Information Systems (TMISs) provide an efficient communicating platform supporting the patients access health-care delivery services via internet or mobile networks. Authentication becomes an essential need when a remote patient ...

During recent years we observe an arms race between new creative methods for inserting effective faults and designing new countermeasures against such threats. Yet, even analyses of an unprotected smart card pose a problem for an analyst assuming ...

Several biometric-based remote user authentication schemes using smart cards have been proposed in the literature in order to improve the security weaknesses in user authentication system. In 2012, An proposed an enhanced biometric-based remote user ...

An integrated EPR (Electronic Patient Record) information system of all the patients provides the medical institutions and the academia with most of the patients' information in details for them to make corrective decisions and clinical decisions in ...

Authentication thwarts unauthorised users from accessing resources in insecure network environments. Password authentication based on smart cards is one of the simplest and most efficient authentication methods and is commonly deployed to authenticate ...
