WAHC 2018 – 6th Workshop on Encrypted Computing & Applied Homomorphic Cryptography

Associated with the ACM CCS 2018 conference
October 19th, 2018
Toronto, Canada


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.


  • Software architectures for encrypted applications
  • Platform and system integration for encrypted applications
  • Algorithmic primitives for encrypted applications
  • Hybrid (partly encrypted) applications
  • Hardware implementations of encrypted computing
  • Implementation of homomorphic encryption schemes
  • Practical performance evaluations of homomorphic encryption schemes
  • Practical aspects of functional encryption
  • Privacy-preserving set operations
  • Secure information sharing
  • Circuit transformation of algorithms
  • Obfuscation techniques
  • Encrypted search schemes
  • Encrypted e-payment solutions
  • Encrypted financial transactions
  • Encrypted applications in bio-informatics


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.
