| Abstract(in English) | In this paper a new type of cryptosystem, proxy cryptosystem, is introduced. The proxy cryptosystem allows an original decryptor to transform its ciphertext to a cihpertext for a designated decryptor, proxy decryptor, and the proxy decryptor can compute a plaintext in place of the original decryptor. It can be applied for questionnaire and file access. Proxy cryptsystems based on the discrete logarithm problem are presented, and their security is discussed. |
