Abstract


With the continuous development of information technology in the power industry , distribution automation system security is facing increasingly severe test . How to protect the security of information distribution automation system , it is a problem to be solved . This paper first introduces the structure of the distribution automation system , communication . The existence of information security risk analysis , pointed out that the use of information encryption technology to solve the problem of eavesdropping and camouflage . Then, the distribution automation system for centralized control mode key management problem , a distribution automation system key management scheme based on elliptic curve cryptosystem design of distribution automation devices , combined with the key management scheme encrypted transmission process . Finally, information encryption process analysis and simulation results show that the process can effectively solve the problem of mutual authentication between the communication entities and information in real-time encryption .
