摘要
A method and apparatus for key revocation in an attribute-based encryption scheme is provided herein. Prior to operation, a key management service performs a randomized setup algorithm resulting in the generation of public parameters and the key management service's master secret, MK. During operation, the key management service is provided with verified user attribute information. The key management service creates keys for users based on their list of attributes. The keys can then be used to decode appropriate ciphertext. During the key creation, each attribute is associated with a particular text string. As attributes are revoked, the text string is updated.
