Improved heterogeneous aggregation signature scheme
Shijin Li, Yijia Gao, Ting Shi, Fushou Tao · 2020
The heterogeneous aggregate signcryption scheme can authenticate the signatures of multiple messages, thereby ensuring the authenticity of the messages. And this technology also solves the communication problem under different cryptosystems. However, most of the current schemes have hidden dangers of insecurity, and the signcryption may be forged, resulting in the leakage of the message ciphertext. In this article, a heterogeneous polymerization signcryption scheme is analyzed, and the forgery process of the scheme is explained, and finally an improvement scheme is given. Our scheme meets the unforgeability, and the final performance analysis proves that this scheme is more efficient than other similar schemes.
