Image authentication is to protect the image integrity when the digital image is illegally modified. Most of the image authentication schemes proposed so far employed the irreversible data hiding approach to embed the authentication data into the cover images. In this paper, a novel reversible image authentication scheme for digital images is proposed. In the proposed scheme, the authentication...

a broadcast authentication protocol enables the receivers to verify that a received packet was really sent by the claimed sender. Data confidentiality, authenticity, integrity, and non repudiation are basic concerns of securing data delivery over an insecure network. Large and distributed systems with time critical applications require immediate and secure authentication of command and control ...

Authentication is required in stored database systems so that only authorized users can access the data and related cloud infrastructures. This paper proposes an `authentication technique using multi-factor and multi-dimensional authentication system with multi-level security. The proposed technique is likely to be more robust as the probability of breaking the password is extremely low. This f...

Two-factor authentication is increasingly demanded in the Internet of Things (IoT), especially those deployed in the critical infrastructure. However, resource and operational constraints of typical IoT devices are the key impediment, especially when the IoT device acts as a verifier. This paper proposes a novel authentication factor (namely, historical data) which, when combined with the conve...

Suppose a principal in a cryptographic protocol creates and transmits a message containing a new value v, later receiving v back in a different cryptographic context. It can conclude that some principal possessing the relevant key has received and transformed the message in which v was emitted. In some circumstances, this principal must be a regular participant of the protocol, not the penetrat...

Mobile phones offer unique advantages for secure authentication: they are small and portable, provide multiple data transfer channels, and are nearly ubiquitous. While phones provide a flexible and capable platform, phone designs vary, and the security level of an authentication solution is influenced by the choice of channels and authentication methods. It can be a challenge to get a consisten...

Multi-hop infrastructure-based communication is expected to play a vital role in supporting high data-rate multimedia access to mobile devices. The advantages are significant in highly mobile scenarios such as intra-vehicular networks. However, mobile nodes in these networks suffer from long authentication delays, which adversely affect the goodput. In this work, we propose two techniques to sh...

As a response to a growing interest in RFID systems such as Internet of Things technology along with satisfying the security of these networks, proposing secure authentication protocols are indispensable part of the system design. Hence, authentication protocols to increase security and privacy in RFID applications have gained much attention in the literature. In this study, security and privac...
