A secure signcryption scheme

الملخص EN

In this paper, a signcryption scheme using an elliptic curve digital signature algorithm is presented.

This scheme like Y.

Zheng signcryption algorithm, combination digital signature function with a symmetric key encryption algorithm but our scheme use an elliptic curve algorithm rather than DSS for signing signcryption offers these two properties at the same time with more efficiently Computational cost in signcryption is considerably reduced as compared signature-then-enrery ption process.
