摘要：
In a key-aggregate encryption scheme, different secret keys for decrypting different categories of ciphertext can be aggregated to a single key, and a ciphertext can be decrypted with the key iff the ciphertext's class belongs to the set which the key includes categories. A promising application of key-aggregate encryption is convenient of data sharing in outside storage. In this work, the authors propose a new key-aggregate encryption scheme. The new scheme is chosen ciphertext secure in ROM and easy to append an additional new class.
