Special Issue Information

Dear Colleagues,

There is a strong need for reliable post-quantum lightweight cryptography.

We are on the brink of the next major shift in the ICT revolution, with the advent of the Internet of Things (IoT) and fifth generation (5G) mobile communications. Currently, there are around 21 billion connected IoT devices, and it is projected that there will be more than 75 billion IoT devices worldwide by 2025. One indisputable fact is that most of these newly networked devices have limited resources. The current standards for symmetric cryptography have been optimized for desktop and server environments. When it comes to resource-constrained devices, these primitive standards are very difficult or impossible to implement. These issues are the subject of the current NIST Lightweight Cryptography Standardization project, which is seeking lightweight authenticated encryption and lightweight hash functions [1].

The situation for post-quantum public-key schemes that can be implemented and used in resource-constrained devices is even more dramatic. The reasons for this are that post-quantum designs have significantly larger public keys, larger signatures, or larger ciphertexts. Thus, it seems that the natural constraints present in lightweight cryptography are a significant restrictive factor for post-quantum public-key design.

The ongoing NIST standardization process for post-quantum public-key schemes is in phase 3 with four proposed finalists for Public-Key Encryption and Key-Establishment Algorithms and three proposed finalists for Digital Signature Algorithms [2]. None of these candidates are designed as lightweight and for resource-constrained environments.

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 papers will be 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. Mathematics is an international peer-reviewed open access monthly 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 1200 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.
