Security access mechanism based on PKI public key system for power monitoring network
Aiming at the problems of network congestion such as various service requests and slow authentication speed in power monitoring network,the principle of data leakage in the process of network communication was deeply analyzed,the secret keys of both sides of communication were dynamically updated according to the challenge-response mode under PKI mechanism,and the Hash function was used to timely authenticate the users′identity before communication.In addition,a secure power monitoring network was designed so that the network node was controlled by information technology.The experimental results show that the as-proposed scheme based on PKI mechanism can achieve the transmission with high security and high reliability for data communication at the expense of lower computing cost compared with the traditional scheme based on symmetric mechanism.In the mutual authentication phase of key agreement,the communication cost of this scheme is about 4%less than that of symmetric mechanism.
