Special Issue Information

Dear Colleagues,

The plethora of new Internet-of-Things (IoT) devices mushroom around us every year, slowly but steadily forming the future of smart infrastructure and contributing to improving the way we live and act. Simultaneously, the trend of personal handheld devices miniaturization has enabled the development of a new IoT niche, namely, wearables and smaller resource-constrained devices. Traditional IoT and machine-to-machine (M2M) solutions and technologies are often implemented as best efforts providing no or very limited quality of service (QoS) or security/reliability control, which is of specific interest for the sensitive data collected and sent by wearable electronics. For this reason, the Special Issue provides a forum to discuss the various issues, trade-offs, methods, and practical experiences related to the further improvement of security, reliability, and dependability of IoT in general, and regarding wearables, as an essential part of the modern IoT ecosystem.

The objective of this Special Issue is to highlight the innovative developments, breakthrough technologies, and challenges related to next-generation systems as well as communication network security. We are soliciting original contributions that have not been published and are not currently under consideration by any other journals; we also welcome extended conference/workshop papers for fast-track reviews. For this Special Issue, we invite regular papers, short letters, and reviews, while encouraging authors to submit multimedia materials and/or open datasets, if they strengthen the contribution for the research community.

The topics of interest include, but are not limited to, the following:

  • 5G/6G network security;
  • Advanced authentication strategies;
  • Attacks on distributed systems;
  • Blockchain aspects;
  • Breach and attack simulation;
  • Cloud, edge, and fog systems security;
  • Communication systems security;
  • Cyber Asset Attack Surface Management (CAASM) tools;
  • Data privacy assurance aspects;
  • Device-to-device (D2D) security;
  • Distributed ledger technology operation aspects;
  • Distributed systems security for public protection and disaster relief (PPDR) scenarios;
  • Enablers for MTC/M2M secure operation;
  • Future Digital Risk Protection Services (DRPSs) for IoT;
  • New consensus algorithms;
  • New consensus algorithms for blockchain;
  • New emerging architectures for security and privacy in IoT applications;
  • Open issues and trends in blockchain-based systems;
  • Peer-to-peer (P2P) systems security;
  • Physical-layer attacks on 5G New Radio (5G NR);
  • Prototypes of distributed systems and related performance evaluation;
  • SDN, NFV, and network slicing security aspects;
  • Security orchestration, automation and response (SOAR).

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cryptography is an international peer-reviewed open access quarterly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Cryptographic key generation and data encryption and decryption using wearable biometric technologies is an emerging research area with significant potential for authentication and communication security. The research area is rapidly developing, and a comprehensive review of recently published literature is necessary to establish emerging challenges. This research article aims to critically investigate and synthesize current research using biometric cryptosystems that use behavior or medico-chemical characteristics, ranging from gate analysis to gaze tracking. The study will summarize the state of knowledge, identify critical research gaps, and provide insight into promising future implications and applications that can enable the realization of user-specific and resilient solutions for authentication and secure communication demands.

The growth of wearable technology has enabled the collection of even more personalized information on individuals. New health-related devices marketed to consumers collect health information that might not fall under the traditional category of Protected Health Information, and thus, HIPAA protections do not fully apply. Meaning, commercial wearable health devices do not fall under FDA oversight, and data not paired with a doctor–patient relationship do not fall under HIPAA privacy protection; thus, much of the gathered health-related metrics are left without regulation and open to be sold to data brokers. As such, these data can be leveraged by health insurance, law enforcement, and employers, to name a few. This manuscript explores the loopholes in current regulations and suggests a framework that categorizes wearable data and addresses challenges in data transfer. Furthermore, taking a user perspective, the suggested framework offers solutions that aim to guide users and policymakers in navigating privacy issues in wearable technology. Full article

The development of Distributed Ledger Technology (DLT) is pushing toward automating decentralized data exchange processes. One of the key components of this evolutionary step is facilitating smart contracts that, in turn, come with several additional vulnerabilities. Despite the existing tools for analyzing smart contracts, keeping these systems running and preserving performance while maintaining a decent level of security in a constantly increasing number of contracts becomes challenging. Machine Learning (ML) methods could be utilized for analyzing and detecting vulnerabilities in DLTs. This work proposes a new ML-based two-phase approach for the detection and classification of vulnerabilities in smart contracts. Firstly, the system’s operation is set up to filter the valid contracts. Secondly, it focuses on detecting a vulnerability type, if any. In contrast to existing approaches in this field of research, our algorithm is more focused on vulnerable contracts, which allows to save time and computing resources in the production environment. According to the results, it is possible to detect vulnerability types with an accuracy of 0.9921, F1 score of 0.9902, precision of 0.9883, and recall of 0.9921 within reasonable execution time, which could be suitable for integrating existing DLTs.

This paper presents a new threshold signature scheme based on Damgaard’s work. The proposed scheme allows for changing the message signature threshold, thereby improving the flexibility of the original Damgaard scheme. This scheme can be applied as a user authentication system using wearable devices. Based on the hardness of lattice problems, this scheme is resistant to attacks on a quantum computer, which is an advantage over the currently used multi-factor authentication schemes. The scheme’s security relies on the computational complexity of the Module-LWE and Module-SIS problems, as well as the Shamir secret sharing scheme’s security. Full article
