Intrusion-resilient signatures are key-evolving protocols that extend the concepts of forward-secure and key-insulated signatures. As in the latter schemes, time is divided into di...

We describe a new encryption technique that is secure in the standard model against adaptive chosen ciphertext (CCA2) attacks. We base our method on two very efficient Identity-Ba...

It has always been a critical issue to find efficient methods for fast revocation of a user's identity in identity (ID)based cryptosystems. Unfortunately, none of the previou...
