We present generic constructions of stateful public key encryption (StPE). We build several new StPE schemes and explain existing ones using our generic constructions. Of the new ...
Most of the work in the analysis of cryptographic schemes is concentrated in abstract adversarial models that do not capture side-channel attacks. Such attacks exploit various for...
An encrypted email is sent from Bob to Alice. A gateway wants to check whether a certain keyword exists in an email or not for some reason (e.g. routing). Nevertheless Alice does n...

In this paper, we propose a notion of threshold tag-based encryption schemes that simplifies the notion of threshold identity-based encryption schemes, and we show a conversion fro...
