Abstract: Proxy Re-Encryption (PRE) is now a primitive encryption used to assign decryption privileges. It was introduced by Blaze, Bleumer and Strauss. With the use of a proxy agent, PRE enables re-encryption of a ciphertext intended for one party to a ciphertext for another party. The underlying message and the sender's private key cannot be read by the proxy agent. The properties of proxy re-encryption systems with different classifications of proxy re-encryption schemes are discussed in this paper.
