The objective is to present the unidirectional proxy re-encryption scheme with chosen-cipher text security. The goal of Proxy Re-Encryption system is to securely enable the re-encryption of cipher texts from one key to another, without relying on trusted parties. A Proxy can transform - without seeing the Plaintext - cipher text encrypted under one key into an encryption of the same plaintext under another key. Proxy Re-Encryption is a form of public-key encryption that allows a user Alice to "delegate" her decryption rights to another user Bob. In a PRE scheme, a proxy is given a piece of information that allows turning a cipher text encrypted under a given public key into an encryption of the same message under a different key.
