Special Issue Information

Dear Colleagues,

Today, digital signatures, as a major and successful application of cryptography, play an essential role in business processes representing the intention of signers. We now see a number of enterprise applications and products that leverage digital signatures in a workflow. Multi-signatures, group signatures, and BBS+ signatures are now within the scope of deployment to handle complicated workflows and business scenarios. Furthermore, in terms of integrity, digital signature technology is fundamental in guaranteeing the integrity of blockchains. Verifiable credentials essentially use digital signatures to claim their integrity. Digital signatures are now studied to extend to apply to new application fields and new cryptography, including lattice cryptography. In this Special Issue, reflecting this growing significance of digital signatures in theory and application scenarios, papers discussing latest advances and prospects of digital signatures in theory and applications are called for.

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. Applied Sciences is an international peer-reviewed open access semimonthly 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 2400 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.

The addressing and discovering service is a vital infrastructure of the Internet. New applications and scenarios in next-generation networks rely on the secure and stable operation of domain name services, which puts forward new security challenges for the original domain name mechanism. While previous security enhancements of network services struggled to strike a balance between security, performance, and compatibility, hindering further use of core network services, the TEE (Trusted Computing Environment) technology can provide trusted and confidential services in untrusted network environments by verifiable hardware signatures. In this paper, we present a novel trustworthy service architecture with the preservation of security and privacy for addressing messages. The scheme provides a secure enclave to generate authenticatable responses between clients and targets, thus ensuring the privacy of services. We further build a new TEE compilation model to ensure that the built resolver application can provide trusted and secure services within TEE while keeping the availability without the TEE hardware. Experimental results show that our approach can enhance the privacy and security of addressing services such as DNS (Domain Name System) without sacrificing the quality of service and breaking the infrastructures of existing services.
