Analysis and improvement of a class of identity-based signcryption schemes
Tang Peng-zh · Journal of Hefei University of Technology · 2014
Through the security analysis of two signcryption schemes,it is found that both schemes can not meet the request for public verification and can not defend the forge by dishonest receiver.Then two improved schemes are proposed which make up the defects of original schemes.The security analysis of the improved schemes is conducted under the random oracle mode.The result shows that the improved schemes are safer and meet the request for public verification and unforgeability.
