Special Issue Information

Dear Colleagues,

A growing number of devices followed by new services and architectures is paving the way towards novel distributed paradigms. From the perspective of information security, the next digital revolution would face several challenges due to unavoidable growth in the complexity of systems. To date, conventional security approaches tend to be limited when applied to decentralized architectures, mainly due to the lack of constantly present trusted authorities or coordination nodes. The cooperation between distributed systems as well as their symbiosis with the conventional centralized ones are the main focus of this Special Issue.

The objective of this Special Issue is to highlight the innovative developments, breakthrough technologies, and challenges related to next-generation systems and communication networks security. We are soliciting original contributions that have not been published and are not currently under consideration by any other journals. Particular emphasis is placed on radically new concepts related to the distributed systems operation. For this Special Issue, we invite regular papers, short letters, and reviews while encouraging authors to submit multimedia materials and/or open datasets, if applicable.

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

  • 6G networks security aspects
  • Advanced authentication strategies
  • Attacks on distributed systems
  • Cloud, edge, and fog systems security
  • Communication systems security
  • 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 secure operation
  • 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
  • PHY-layer attacks on 5G New Radio (5G NR)
  • Prototypes of the distributed systems and related performance evaluation
  • SDN, NFV, Network Slicing security aspects
  • State-of-the-art and new security concepts and protocols for distributed systems
  • Systems vulnerability analysis and penetration testing
  • Wearable devices security

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

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.

With the huge transfers of data involved in the modern world, it is both crucial and challenging to maintain the security of data. This paper proposes a novel algorithm of information embedding into digital images that could be used to protect confidential information. The presented algorithm makes use of the Chinese remainder theorem and adaptive embedding to achieve good imperceptibility along with the possibility of hiding a decent amount of confidential information. The algorithm is evaluated via computing experiments and evaluation results, as well as comparison with similar works, demonstrate good imperceptibility qualities of the proposed scheme. Full article

Security and access control aspects are becoming more and more essential to consider during the design of various systems and the tremendous growth of digitization. One of the related key building blocks in this regard is, essentially, the authentication process. Conventional schemes based on one or two authenticating factors can no longer provide the required levels of flexibility and pro-activity of the access procedures, thus, the concept of threshold-based multi-factor authentication (MFA) was introduced, in which some of the factors may be missing, but the access can still be granted. In turn, secret sharing is a crucial component of the MFA systems, with Shamir’s schema being the most widely known one historically and based on Lagrange interpolation polynomial. Interestingly, the older Newtonian approach to the same problem is almost left without attention. At the same time, it means that the coefficients of the existing secret polynomial do not need to be re-calculated while adding a new factor. Therefore, this paper investigates this known property of Newton’s interpolation formula, illustrating that, in specific MFA cases, the whole system may become more flexible and scalable, which is essential for future authentication systems.
