Abstract :
The concept of proxy re-cryptography comes from the work of Blaze, Bleumer, and Strauss in 1998. The goal of proxy re-encryption is to securely enable the re-encryption of ciphertexts from one key to another, without relying on trusted parties. Identity based proxy re-encryption extends proxy re-encryption to the identity based setting. In this paper, we construct an identity based proxy re-encryption (IBPRE) scheme which can achieve master secret secure, while almost all of the previous efficient IBPRE schemes can not.
