Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, expression the utility model distribution network system only comprises the framework of a substation.This distribution network system comprises by network link and connects substation and main website, and the substation and the some power distribution network terminals that connect by communication link, and power distribution network terminal inspection device is connected with main website by network link.
Network link in the present embodiment can be mobile radio communication, Internet etc., is preferably mobile radio communication, specifically can be the standard mobile nets such as GPRS, CDMA, 3G.Be without loss of generality, the below describes as an example of the GPRS communication network example.
As shown in Figure 1, described substation links to each other with the main website server by network link, thereby impels external network to be connected to substation and main website by network link.Therefore, can attack the substation by public network, cause customer power supply to interrupt; Can also by public network and user terminal invasion main website, cause wider security risk.
Referring to Fig. 2, for above-mentioned reasons, main website is provided with data encryption module, and described data encryption module comprises encryption device, is encrypted by the director data of encryption device to the needs below, is sent to the substation again.Described data encryption module is by adopting the unidirectional authentication measure of asymmetric encryption techniques; realize integrity protection and the main website identity discriminating of control (or parameter setting) data message, add simultaneously time tag (or random number) and guarantee the ageing of control data message.Main website uses private key that whole control (or parameter setting) command message and timestamp (or random number) are signed, and digital signature is trailed form interdictum duplex message and transmission behind former control command message.
Described data encryption module adopts unilateral authentication and the message integrity protection of realizing control command and parameter setting instruction based on the asymmetric key algorithm of main website certificate, and asymmetric key algorithm is selected the oval curve cryptography system of ECC() (more than the 160bit) algorithm.
Described substation is provided with the data deciphering module, comprise decryption device, deposit in the decryption device by the main website PKI with prepackage, the control command and the parameter setting instruction that derive from main station system are taked authentication and data integrity checking measure, pretend to be main website that the substation terminal is attacked with strick precaution, the malicious operation electric equipment.
With reference to Fig. 2, after the interdictum duplex message is received in the substation, use the main website PKI of prepackage that the signature in the interdictum duplex message is carried out sign test, and the comparison timestamp is ageing, if the verification passes, then fill order is sent to the power distribution network terminal, carried out by the power distribution network terminal.
