Most1 certificateless signcryption schemes are based on bilinear pairing operations. Thus, the computation efficiency is low. In this paper, a new signcryption scheme without certificate and linear pairing is proposed. This scheme is proved to be secure in therandom oracle model under the hardness assumption of computational the problem of discrete logarithm. In addition, the user's partial private key can be verified. Compared with other schemes, the scheme is more optimized in terms of security and computation efficiency.
