Abstract(in English) | Today, some participants in communication networks take an anonymity into consideration. There is the possibility that an attacker, which can intercept all of the messages in the network, threaten the anonymity of sender and receiver. Recently, Golle et al. proposed a new re-encryption scheme, called universal re-encryption. In this scheme, re-encryption algorithm does not require any public information of receiver associated with a ciphertext. The subject who carries out re-encryption can only knows relationships between original and re-encrypted ciphertext. The anonymity is based on the semantic securecy. In this paper, we study the signature schemes associated with universal re-encryption, and touch the security. |
