IDFIX - ID-based cryptography For Identification and eXchange

Project Description:

The ID-Fix project aims to improve authentication methods in everyday communication. Usually there is a clash between two worlds at this level, on one hand academic research tends to propose solutions proven secure in some abstract model without real consideration for efficiency, while industrial tends to favor optimization without sufficient concerns for security or the lack thereof, another main issue is that those implementations often tend to consider a Trusted Third Party, and end up relying way too much on its honesty, while no system can be guaranteed no never be corrupted or coerced into evil-doing.

This project will take the best of both worlds, by producing protocols secure in model fitting realistic applications, with proper security proof, and practical efficiency.
For that, we will undergo a pass on classical interactive protocols, revisit their security model and propose alternative way to achieve the same functionalities, and as much as possible in the ID-based setting.
