Search over encrypted records: from academic dreams to production-ready tool

The search over encrypted data is the modern cryptographic engineering problem. We will talk about existing approaches (both well-known and modern), and concentrate on practical solution based on blind index technique to search data in databases. What’s inside: cryptographic and functional schemes, implementation details, practical security evaluation (risk modelling and potential attacks). We will show how theoretical models turn into real, usable, maintainable, security tools. Search over encrypted records is part of Acra encryption proxy.
