Although there are many quantum key agreement protocols currently in existence, they cannot be merged in terms of resource utilisation, efficiency, security, and other aspects, and there are also significant differences in the nature of two and more ...

Although block ciphers are widely used and are quite secure, there are still many types of attacks against components of block ciphers, and the Advanced Encryption Standard (AES) block cipher is no exception. To improve the security of AES, there have ...

RSA is a well-known public key cryptosystem in modern-day cryptography. Common prime RSA (CP-RSA) is a variant of RSA which is introduced by Wiener to avoid the small secret exponent attack on RSA. Lattice-based reduction algorithms were successfully ...

In this article, we propose a method to construct self-orthogonal matrix, orthogonal matrix and antiorthogonal matrix over the finite field. Orthogonal matrices have numerous applications in cryptography, so here we demonstrate the application of ...

The presence of missing data in a dataset plays a vital role in the design of classification, clustering, or regression methods. An efficient missing data imputation can enhance the overall performance of a machine learning method. This paper ensembles k-...

Distributed denial of service, DDoS, attacks are drastically increasing, therefore, they cause serious threats for information networks. This paper proposes, for the first time, the use of a graph theoretic approach to exploit the entropy techniques for ...

In this paper, a new substitution-diffusion type chaos-based cryptosystem is proposed, which can encrypt greyscale images having arbitrary resolution. In substitution, image pixels are permuted using a modified form of the discretised 2-D Baker map, ...

The tower field implementation of the 𝔽_2⁸ inverter is not only the key technique for compact implementations of the S-boxes of several internationally standardised block ciphers such as AES, Camellia, and SM4, but also the underlying structure many side-...

Many real problems involve the simultaneous security of computer networks and systems as it penetrates all areas of our daily lives. The purpose of attack graph analysis is to be able to protect computer systems and networks against attacks related to ...

Universal hashing-based message authentication code (MAC) is used as the de facto method to achieve information-theoretically secure authentication in quantum key distribution. We present a critical look at the most widely used type, namely Wegman-Carter ...

Production scheduling and vehicle routing are integrated to solve a task scheduling problem with a timing requirement in cloud computing. The issues of multiple compute resources for a lot of tasks are considered. In the tasks scheduling problem, each ...

In order to improve the accuracy of network traffic prediction and overcome the disadvantages of slow convergence speed and easy to fall into local minimum value in the process of least squares support vector machine (LSSVM) network traffic prediction, a ...

Aiming at the problem that the existing one-dimensional chaotic system has small chaotic interval, Lyapunov exponent is small and the generated chaotic sequence is unevenly distributed, and the correlation is high, a new image encryption algorithm is ...

Steganography is the art of concealing secret information within digital media. In this paper, an adaptive steganographic scheme based on Faber-Schauder discrete wavelet transform (DWT) is proposed. Data is hidden in the details coefficients, which are ...

The huge dependability on software systems has led to the need of reliable software in a short span of time. One of the ways to achieve this is to provide a series of versions of the software system. Thus, firms release the first software version with the ...

Moving target defence mainly focus on the single parameter hopping and rarely refer to the hopping of multiple parameters in multiple layers. With the background of database security, this paper constructs a layer-crossing, multi-parameter and dynamic ...

The proliferated complexity of network size together with the expeditious development of software system applications and their large number of vulnerabilities, security hardening is becoming a challenge for security specialists. Operating systems and ...

Software vulnerabilities primarily constitute security risks. Commonalities between faults and vulnerabilities prompt developers to utilise traditional fault prediction models and metrics for vulnerability prediction. Although traditional models can ...

A one-dimensional chaotic logarithmic map (CLM) is proposed. Characteristics of the CLM are investigated and used to develop a symmetric handwriting document encryption scheme that consists of three phases. The segmentation phase divides a handwriting ...

Kakvi and Kiltz (EUROCRYPT'12) proposed the first tight security reduction for RSA full domain hash signature scheme (RSA-FDH) with public exponent e < N^1/4 in the random oracle (RO) model, and they left an open problem which called for a tightly secure ...
