What is Transformation-free Proxy Cryptosystems and Their Applications to Electronic Commerce about?

ht this paper transformation-free proxy cryptosystems (TFP systems) are studied. The TFP system is a modification of the proxy cryptosystem introduced by Mambo mid Okamoto in which a ciptmrtext trmmformation by the original decryptor is necessary. The TFP system allows proxy decryptor to do decryption without any ciphertext transformation, so that it can release the original decryptor more efficiently from a large amount of decryptfilg operations. An active identity-based a~ld a directory-based TFP systems based on pairings are proposed. ~lrthermore, two applications of directory-based TFP system in electronic commerce are also investigated.
