We initiate the study of security for key-dependent messages (KDM), sometimes also known as “circular” or “clique” security, in the setting of identity-based encryption (I...

A proxy re-encryption scheme allows Alice to temporarily delegate the decryption rights to Bob via a proxy. Alice gives the proxy a re-encryption key so that the proxy can convert ...

In this paper we introduce a new primitive called identity-based encryption with wildcards, or WIBE for short. It allows a sender to encrypt messages to a whole range of receivers ...

In a proxy re-encryption scheme a semi-trusted proxy converts a ciphertext for Alice into a ciphertext for Bob without seeing the underlying plaintext. A number of solutions have ...

We present the first identity-based traitor tracing scheme. The scheme is shown to be secure in the standard model, assuming the bilinear decision Diffie-Hellman (DBDH) is hard in...
