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.

in combination digital signature function with a symmetric key encryption algorithm but our scheme use an elliptic curve algorithm rather than DSS for signing.

A signcryption offers these two properties at the same time with more efficiently.

Computational cost in signcryption is considerably reduced as compared to signature-thenencryption process.
