Special Issue Information

Dear Colleagues,

Today, we all live today in a cyber world, and modern technologies involve fast communication links, potentially between billions of devices, via complex networks (satellites, mobile phones, the Internet, etc.). Thus, the question of how we protect public communication networks and devices from passive and active attacks that could threaten public safety (sabotage, espionage, cyber terrorism) and personal privacy has become one of great significance—especially considering that governments themselves are often suspected of promoting and actively participating in the hacking of other government officials, democratic processes, industrial secrets, and citizens, with hackers targeting the sensitive information of citizens, industries, and governments. This is a real threat, and it is escalating.

One of the main avenues of protecting public safety and personal privacy is that of protecting most of the communication network traffic (digital multimedia contents such as images, speech signal, videos and emails, etc.), which is vulnerable to various security threats taking place in different societies and within several societal levels.

The objective of this Special Issue on “Cryptography and its Applications in Information Security” is to address the range of problems related to the security of information in networks and multimedia communications and to bring together researchers, practitioners, and industry experts interested in such questions. We welcome papers both from theoretical and practical aspects. Prospective authors are invited to submit original work reporting on novel and significant research contributions, ongoing research projects, experimental results, and recent developments related but not limited to the following topics:

  • Cryptography
  • Cybersecurity
  • Chaos-based cryptography
  • Quantum Cryptography

To address the quantum attacks on number theory-based ciphertext policy attribute-based encryption (CP-ABE), and to avoid private key leakage problems by relying on a trustworthy central authority, we propose a lattice-inspired CP-ABE scheme for data access and sharing based on blockchain in this paper. Firstly, a CP-ABE-based algorithm using learning with errors (LWE) assumption is constructed, which is selective security under linear independence restriction in the random oracle model. Secondly, the blockchain nodes can act as a distributed key management server to offer control over master keys used to generate private keys for different data users that reflect their attributes through launching transactions on the blockchain system. Finally, we develop smart contracts for proving the correctness of proxy re-encryption (PRE) and provide auditability for the whole data-sharing process. Compared with the traditional CP-ABE algorithm, the post-quantum CP-ABE algorithm can significantly improve the computation speed according to the result of the functional and experimental analysis. Moreover, the proposed blockchain-based CP-ABE scheme provides not only multi-cryptography collaboration to enhance the security of data access and sharing but also reduces average transaction response time and throughput.

Trojan Detection—the process of understanding the behaviour of a suspicious file has been the talk of the town these days. Existing approaches, e.g., signature-based, have not been able to classify them accurately as Trojans. This paper proposes TrojanDetector—a simple yet effective multi-layer hybrid approach for Trojan detection. TrojanDetector analyses every downloaded application and extracts and correlates its features on three layers (i.e., application-, user-, and package layer) to identify it as either a benign application or a Trojan. TrojanDetector adopts a hybrid approach, combining static and dynamic analysis characteristics, for feature extraction from any downloaded application. We have evaluated our scheme on three publicly available datasets, namely (i) CCCS- CIC-AndMal-2020, (ii) Cantagio-Mobile, and (iii) Virus share, by using simple yet state-of-the-art classifiers, namely, random forest (RF), decision tree (DT), support vector machine (SVM), and logistic regression (LR) in binary—class settings. SVM outperformed its counterparts and attained the highest accuracy of 96.64%. Extensive experimentation shows the effectiveness of our proposed Trojan detection scheme. Full article

This work proposes a new secure chaos-based encryption/decryption system, operating in cipher block chaining (CBC) mode, and analyze its performance. The cryptosystem includes a robust pseudorandom number generator of chaotic sequences (PRNG-CS). A strong chaos-based S-box is proposed to perform a circular substitution operation (confusion process). This PRNG-CS consists of four discrete 1-D chaotic maps, weakly coupled by a predefined coupling matrix M, to avoid, on the one hand, the divide-and-conquer attack and, on the other hand, to improve the generated sequence’s randomness and lengths. The noun is also used in the construction of the S-box. Moreover, a 2-D modified cat map and a horizontal addition diffusion (HAD) preceded by a vertical addition diffusion (VAD) are introduced to perform the diffusion process. The security analysis and numerous simulation results of the main components (PRNG-CS and S-box) as well as the whole cryptosystem reveal that the proposed chaos-based cryptosystem holds up against various types of statistical and cryptographic attacks.
