Special Issue Information

Dear Colleagues,

Private information retrieval (PIR) refers to the scenario where a user wishes to download content from an untrusted (and possibly distributed) database without revealing which records he or she is interested in. PIR dates back to the mid-1990s and the literature on the topic is vast. However, in the digital age, with the surge of distributed information systems, strong privacy concerns have arisen. This has spurred a new wave of research on PIR, which is now a very active research area within the information theory and computer science communities. Despite many recent advances in the area, important research problems still remain open. For example, the fundamental limits of PIR are still unknown in several important scenarios, and several practical aspects of PIR remain to be solved, so that it leaves the realm of research and becomes a reality in the real world.

This Special Issue invites submissions of high-quality original technical and survey papers in this very vibrant area, addressing both theoretical and practical aspects of PIR, hopefully inspiring researchers to identify practical use cases.

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 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. Information 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 1000 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.
