Design of Secure Communication Protocol in Energy Internet Scenario

We propose a security interaction protocol in the energy Internet scenario, which solves secure problems of business data, such as the lack of security protocol in the energy Internet, data plaintext transmission, easy tampering, lack of integrity verification, and lack of authorization mechanism of the business data. We use additive homomorphic encryption technology to encrypt sensitive data, the decryptor can get the aggregation result without knowing the single information of the encryptor. We protect data privacy and reduce the load of intermediate decryption. We use the multi-level hash algorithm to verify the integrity of data, and adopt the shadow identity and tracking serial number to realize synchronization, to avoid a replay attack. We use the attribute-based access control method to realize the fine-grained access control of the data. Finally, we give the structure field and interaction mechanism of the new protocol frame. The designed protocol can effectively prevent unauthorized users from decrypting information, unauthorized users from obtaining sensitive data, dictionary attacks, replay attacks, repudiation, and maintain the efficiency of the protocol.
