报告简介:

Broadcast encryption is a useful tool in the data sharing which allows a message to be shared with a group of authorized users. Traditionally, a ciphertext from an identity-based broadcast encryption can be decrypted by the users whose identities are included in the ciphertext. Once the ciphertext has been created, it is not possible to remove any intended receivers from it without conducting decryption. We consider how to revoke users' identities from the ciphertext without the knowledge of the plaintext and the knowledge of the receivers. The solution to this question is found applicable to data sharing in the cloud computing. We design an anonymous identity-based broadcast encryption, which offers the user revocation of ciphertext and the revocation process does not reveal any information of the plaintext and receiver identity. In our proposed scheme, the group of receiver identities are anonymous and only known by the encryptor.
