Outline of Final Research Achievements	Timed-Release Encrtption(TRE) is an encryption mechanism that allows a reciever to decrypt a ciphertext only after the time that a sender designates. We proposed a notion of certificateless encryption scheme with TRE encryption mechanism, Timed-Release Certificateless Encryption(TRCLE), and defined its security model. Moreover we presented a secure generic construction of TRCLE.
