Abstract This paper presented an efficient and secure identitybased encryption scheme. Compared to the previous scheme, it has the advantage of security or efficiency. This new scheme can achieve adaptive CCA2security under BDH assumption with tight reduction. The construction was made by use of the “Twin DiffieHellman” technique proposed by Cash et al, only requiring one pairing computation during the encryption procedure.
