摘要
针对电力市场在交易过程中存在的数据交互安全性问题,提出一种基于Paillier同态加密的电力交易数据加密方案。分析电力交易业务流程和数据传输特征,结合Paillier算法同态特性,进行电力交易数据的“一次交易数据密文+公钥”二次加密以提高数据交互的安全性。通过试验,验证方案的效率和加解密正确率等性能,并进行对比分析。结果表明,方案能有效保障数据完整性和安全可靠传输。
Aiming at the security problem of data interaction in the electricity market during the transaction process,a power transaction data encryption scheme based on Paillier homomorphic encryption was proposed.With this scheme,the power transaction business process and data transmission characteristics were analyzed,combined with the Paillier algorithm’s homomorphic characteristics,the so-called“One Transaction Data Ciphertext+Public Key”secondary encryption of power transaction data was carried out to improve the security of data interaction.Through experiments,the efficiency and encryption and decryption accuracy of the scheme were verified and compared.The results show that the scheme can effectively guarantee data integrity and safe and reliable transmission.
