The security protection system of the secondary power system has no central management and auditing

and the public key algorithm of existing security systems is RSA algorithm. So a design and implementation scheme for security supporting platform based on domestic SM2 cryptosystem is proposed. First

the difficulty in making the security supporting platform upgraded to support the SM2 algorithm is pointed out. Then a scheme of building the self-developed security encrypted channel with the component technology is proposed to ensure the SM2 algorithm can be realized in the security supporting platform. Finally

the application function of integrated security supporting platform is tested and analyzed. The results show that this platform can achieve smooth integration among the applications of the secondary power system

while providing safe identity authentication

effective access control and authorization management

safety auditing logging

and user management. What’s more

the security support platform can centralize the identity authentication and the access control. The platform has been applied in a certain provincial power grid

which has proved its availability in actual projects.
