The Internet of Things (IoT) based healthcare system is one of the prominent approaches to overcome the issue of the increasing burden of healthcare costs in India. Wireless Body Area Networks (WBANs) are the key enabler in this scenario. It provides continuous monitoring of the patient’s health condition remotely, by making the real-time health data of the patient available to healthcare professionals

Proxy Re-encryption (PRE) offers an efficient solution for enforcing access control on outsourced data through delegation of decryption rights of a delegator to a delegatee. However, to meet practical security requirements of an access control model, the delegator must control these delegations such that a re-encryption key enables the delegation of decryption rights of only a subset of the delegator’s

The concept of Supply Chain Management (SCM) is very imperative while moving sensitive products from one entity to the next entity until it reaches to the end-users to avoid damage(s) in the product. In the traditional supply chain management system, several serious problems such as tampering of products, delay, and fraud, etc. exist. It also lacks proper authentication among the participants, data

The two-party authenticated key agreement (2PAKA) protocol establishes a secure channel over the Internet between two users. This secure channel helps to transfer messages between them in the presence of an adversary. The invention of Shor’s algorithms makes current 2PAKA protocols vulnerable to quantum attacks. To mitigate quantum attacks, we designed an identity-based two-party authenticated key

The hierarchy theory is the foundation of the modern computer system design. However, the interaction part between different system layers is usually the weak point of the system, which tends to have security flaws. When communicating across the system boundary, failure to enforce the required synchronization in the shared memory can cause data inconsistency of the communication partners. Especially

In recent years, the chaotic systems in engineering applications attracted many researchers. One of the most important applications of chaos theory is the production of pseudo random numbers that can be used in different areas of cryptography, signal processing, and a variety of other fields. In production of pseudo random numbers generators the chaotic maps are the source of entropy for producing

Secure IoT (SIT) is a popular encryption algorithm that tends to consume less hardware resources due to simple operation, which serves a welcome advantage, since it is precisely

Telecare Medical Information System (TMIS) is a platform for the patients and the medical server to communicate and exchange data through the Internet. As the Internet is an insecure medium, the shared sensitive data is at troublesome situation. To protect sensitive data over the public network, it is essential to have secure communication. The authentication and key establishment protocol supports

In the Healthcare 4.0 era, recent breakthroughs in emerging and disruptive technologies, such as Artificial Intelligence (AI), machine learning and robotics, have significantly changed the way in which healthcare services are delivered to patients. Advancements in patient monitoring systems and wearable devices have created more powerful and flexible real-time remote patient observation. Healthcare

Since Wiener pointed out that the RSA can be broken if the private exponent d is relatively small compared to the modulus N, it has been a general belief that the Wiener attack works for d

We study efficient and lightweight Intrusion Detection Systems (IDS) for ad-hoc networks via the prism of IPv6-enabled Wireless Sensor Actuator Networks. These networks consist of highly constrained devices able to communicate wirelessly in an ad-hoc fashion, thus following the architecture of ad-hoc networks. Current state-of-the-art (IDS) has been developed taking into consideration the architecture

Distributed denial of service attack is one of the most dangerous attacks in cloud computing. This attack makes the cloud services inaccessible to the end-users by exhausting resources, resulting in heavy economic and reputation loss. So, developing defensive solutions against these attacks is necessary for the widespread adoption of cloud computing technology. This paper proposes a new system for

Elliptic curve cryptography is an essential cryptography which is widely used in data encryption, key agreement, digital signature, and other applications. Scalar multiplication is the fundamental operation in all ECC schemes, such as ECDSA, ECIES, and ECMQV. Even a slight improvement of scalar multiplication is precious. Various methods have been proposed for improving efficiency of the scalar multiplication

Image security is very important to protect from any unauthorised user access. In this paper a two-phase secure image encryption has been proposed using the concepts of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA). First, the plain image is encrypted based on DNA rules, DNA XOR operator, and chaotic map function in DNA phase and initial cipher image is created. Next, the cipher image is used

Median filtering is a widely used method for removing noise, preserving edges and smoothing regions within an image. Detection of median filtering has drawn much attention from researchers of image forensic. A new robust detection scheme of median filtering based on combined features of difference image is proposed in this paper. In the proposed approach, the combined features consist of data-pair

Artificial neural networks tend to use only what they need for a task. For example, to recognize a rooster, a network might only considers the rooster’s red comb and wattle and ignores the rest of the animal. This makes them vulnerable to attacks on their decision making process and can worsen their generality. Thus, this phenomenon has to be considered during the training of networks, especially in

Location fingerprinting is a technique employed when Global Positioning System (GPS) positioning breaks down within indoor environments. Since Location Service Providers (LSPs) would implicitly have access to such information, preserving user privacy has become a challenging issue in location estimation systems. This paper proposes a low-complexity k-anonymity approach for preserving the privacy of

The classification is one of the important machine learning technologies, which plays an important role in the fields of medical treatment, image processing, and cyberspace security. In recent years, the popularity of cloud computing has caused many data owners to seek outsourced storage computing, which has become a new trend in the development of classification. Although it can be used in several

The authentication protocol for HTTP proposed in RFC 8120 has been model checked under different assumptions. Four security properties have been taken into account: (1) Key Secrecy Property (K-SEC), (2) Key Sharing Property (K-SHR), (3) Correspondence Property from a client point of view (C-CORR), and (4) Correspondence Property from a server point of view (S-CORR). In each assumption, we suppose that

Fingerprint is the most well-known and successfully deployed biometric modalities in view of its ease of acquisition, established use, acceptance and high recognition rate (i.e., robustness). This is also due in part to its use in crime scene investigations to link crimes to suspected individuals. One form of fingerprint is called the latent fingerprint. Despite its subtle appearance, the latent fingerprint

To allow more general key derivation patterns, the concept of wicked identity-based encryption (wicked IBE) was introduced. It is an extension of hierarchical identity based encryption (HIBE). Recently, research on leakage-resilient wicked IBE has attracted much attention for its consideration on the problem of key leakage in system. However, the existing works implement leakage resistance under the
