By integrating the concepts of self-certified public key and signcryption,a secure and efficient self-certified signcryption scheme from bilinear pairings is proposed.It can guarantee the confidentiality and authenticity when the message is transmitted and prevent certificate authority to personate the user.The verifier can verify the authenticity of public key and validate signcryption simultaneously.The scheme is more efficient than the existing ones in terms of communication overheads and computation cost.It have more practical value in applications of E-commerce and other fields.
