摘　　要：针对智能电网中的数据安全传输问题,文中提出了一种面向电力数据安全的轻量化传输方案。该方案将量子密码与“一次性加密”机制相结合,使用量子随机数发生器弥补了传统设备和量子密钥分发协议的不足,进而保证密钥分发的安全性,并设计了一种新的轻量级流密码加密算法。通过理论分析及实验结果证明,所设计的数据通信方法在安全性方面可以有效抵御攻击;而在性能方面其运行时间能够保持在0.14~0.18 s之间,在明文长度为5 000 Bytes时相比DES降低了约0.4 s,且所需内存开销也小于其他算法,说明该传输方案能够保证电力数据传输的安全性与稳定性。In view of the problem of data security transmission in smart grid,this paper proposes a lightweight transmission scheme for power data security.This scheme combines quantum cryptography with“one⁃time encryption”mechanism,uses quantum random number generator to make up for the shortcomings of traditional devices and quantum key distribution protocols,thus ensuring the security of key distribution,and designs a new lightweight stream cipher encryption algorithm.Through theoretical analysis and experimental results,it is proved that the designed data communication method can effectively resist attacks in terms of security;In terms of performance,its running time can be kept between 0.14 s and 0.18 s.When the plaintext length is 5000 Bytes,it is reduced by about 0.4 s compared with DES,and the memory overhead required is also less than other algorithms,indicating that the transmission scheme can ensure the security and stability of power data transmission.
