Registration is through CCS.


Secure computation is becoming a key feature of future information systems. Distributed network applications and cloud architectures are at danger because lots of personal consumer data is aggregated in all kinds of formats and for various purposes. Industry and consumer electronics companies are facing massive threats like theft of intellectual property and industrial espionage. Public infrastructure has to be secured against  sabotage and manipulation. A possible solution is encrypted computing: Data can be processed on remote, possibly insecure resources, while program code and data is encrypted all the time. This allows to outsource the computation of confidential information independently from the trustworthiness or the security level of the remote system. The technologies and techniques discussed in this workshop are a key to extend the range of applications that can be securely outsourced.

The goal of the workshop is to bring together researchers with practitioners and industry to present, discuss and to share the latest progress in the field. We want to exchange ideas that address real-world problems with practical approaches and solutions.


Professionals, researchers and practitioners in the area of computer security and applied cryptography with an interest in practical applications of homomorphic encryption, encrypted computing, functional encryption and secure function evaluation, private information retrieval and searchable encryption.

Proceedings of the workshop will be published by ACM on a CD, available to the workshop attendees. Papers will be included in the ACM Digital Library, with a specific ISBN.

A paper submitted to WAHC must be written in English and be anonymous, with no author names, affiliations, acknowledgements, or any identifying citations. It should begin with a title and a short abstract. Submissions must be single PDF files, no more than 12 pages long in double-column ACM format (the sigconf template from https://www.acm.org/publications/proceedings-template, with a simpler version at https://github.com/acmccs/format), including references and appendices. Authors should not change the font or the margins of the ACM format. Submissions not following the required format may be rejected without review. We also encourage authors to submit Demos which are limited to 6 pages and feature an oral presentation with an extensive code review. Authors are invited to submit their work via the HotCRP submission server.
