Abstract: In this paper, we present a new proxy cryptosystem named subject-delegated decryption scheme, in which the original decryptor delegates decryption authority to multiple proxies according to di#erent subjects. The advantage of our scheme is that the proxy authorities are tightly limited ("Tightly" Limited Authority). This means that the proxy authority can be temporarily aborted even if the validity period of the proxy key does not expire. Consequently, our protocol is more practical than ... (Update)
