- Signcryption scheme is one of the useful tools for secure communication where authenticity and confidentiality are simultaneously required. Now, mobile devices are more and more widely used for communication, and thus it is desirable to design a scheme suitable to mobile applications. In this paper, we propose a signcryption scheme which is efficient enough to be implemented on mobile devices. In our scheme, we need only one multiplication in an online phase, and thus a signcryptor can generate a signcryptext very efficiently in the online phase. Moreover, the size of signcryptext is very short compared with exsiting schemes, and thus our scheme is very efficient in terms of communication overhead. The security of our signcryption scheme is proven in the random oracle model. © 2012 Science China Press and Springer-Verlag Berlin Heidelberg.
