Unidirectional Chosen-Ciphertext Secure Proxy Re-Encryption
Abstract. In 1998, Blaze, Bleumer, and Strauss proposed a cryptographic primitive called proxy re-encryption, in which a proxy transforms – without seeing the corresponding plain...

Chosen-Ciphertext Secure Proxy Re-encryption without Pairings
Proxy re-encryption (PRE), introduced by Blaze, Bleumer and Strauss, allows a semi-trusted proxy to convert a ciphertext originally intended for Alice into an encryption of the sa...

Chosen-Ciphertext Attacks Against MOSQUITO
Self-Synchronizing Stream Ciphers (SSSC) are a particular class of symmetric encryption algorithms, such that the resynchronization is automatic, in case of error during the transm...

Chosen Ciphertext Security with Optimal Ciphertext Overhead
Every public-key encryption scheme has to incorporate a certain amount of randomness into its ciphertexts to provide semantic security against chosen ciphertext attacks (IND-CCA). ...
