A public key trace and revoke scheme combines the functionality of broadcast encryption with the capability of traitor tracing. In Asiacrypt 2003, Kim, Hwang and Lee proposed a public key trace and revoke scheme (referred to as KHL scheme), and gave the security proof to support that their scheme is z-resilient against adaptive chosen-ciphertext attacks, in which the adversary is allowed to adaptively...
Traditional identity-based signature (IBS) schemes typically rely on the assumption that secret keys are kept perfectly secure. However, with more and more cryptographic primitives are deployed on insecure devices such as mobile devices, key-exposure seems inevitable. No matter how strong the IBS scheme is, once the secret key is exposed, it will be broken completely. Therefore how to deal with this...
