Research on Fusion Algorithm of Elliptic Curve Cryptography in Advanced Metering Infrastructure Communication

According to the information security requirements of Advanced Metering Infrastructure communication, combining with the characteristics of elliptic curve cryptography, this paper gives a fusion algorithm based on elliptic curve cryptography. The proposed fusion algorithm constructs a decision function to verify the validity of the cipher text that attacker proposed, refuses to accept the illegal cipher texts of attacker based on achieving the digital signature and encrypting communications messages, and provides measuring method for defending illegal messages intrusion initiatively. The research results show that the proposed fusion algorithm meets information security demands of Advanced Metering Infrastructure.
