Abstract: Signcryption can finish encryption and signature in one logical step. Compared with traditional encryption scheme, signcryption is more efficient. Compared with the cryptographic schemes using bilinear pairings, the cryptographic schemes without bilinear pairings have a great improvement in computational efficiency. An improved certificateless signcryption scheme without bilinear pairings is proposed. The security of the scheme is proved under the random oracle model, and the scheme is analyzed by experiments.

Key words: certificateless signcryption, random oracle model, without bilinear pairing
