摘要：
A method for secure transmission of a message encrypted under an attribute based encryption scheme is provided. A first and a second authority parameter may be received from one or more authorities. A policy is generated based on the parameters. The generated policy comprises a flexible access control structure. A ciphertext is constructed based on the policy. To decrypt the ciphertext, key components are received from one or more authorities, the key components associated with a decryptor identifier. A decryption key is generated based on the policy and the key components. A plaintext is generated by decrypting the ciphertext.
