摘要: 在智能电网的大趋势下,电力公司与用户之间的数据传输交换愈加频繁高效。通信网络经常遭受网络攻击或窃听,为确保用户的用电数据在传输过程中不被恶意篡改,提出一种面向电动汽车用户的信息保护方案。通过改进加法运算和标量乘运算对传统椭圆曲线加密算法(elliptic curve cryptography, ECC)做轻量级优化,克服电网双向互动环境中智能电表资源有限的问题。在此基础上,设计负荷分解算法作为加密方案的检验工具,分解加密后的电力数据。最后,通过仿真算例分析,验证了所提方案的可靠性和安全性。

Abstract: In the trend of smart grid, data transmission and exchange between power companies and users become more frequent and efficient. The communication network is often attacked or eavesdropped. In order to ensure that the user 's electricity data is not maliciously tampered during transmission, an information protection scheme for electric vehicle users is proposed. By improving the addition operation and scalar multiplication operation, the traditional elliptic curve cryptography(ECC) is lightly optimized to overcome the problem of limited smart meter resources in the two-way interactive environment of the power grid. On this basis, the load decomposition algorithm is designed as a test tool for the encryption scheme to decompose the encrypted power data. Finally, the reliability and security of the proposed scheme are verified by a simulation example.
