Application of Trusted Computing Technology in Active Defense of Smart Substation
Journal of Physics: Conference Series(2021)
Abstract
Abstract Nowadays, most security systems mainly use firewall, intrusion detection, virus killing and other technologies to defend against external attacks. This passive defense mode has low efficiency and high false positive rate, and active defense technology can solve these problems to the greatest extent. At present, the intelligent substation is in the development stage with weak security. After a large number of terminals are connected, although the operation efficiency of the whole station is improved, it also brings more risks. This paper takes the access security of terminal equipment in intelligent substation as the research object. By mining the security vulnerabilities of substation, an active defense method based on trusted computing is proposed, the applicability and efficiency of trusted computing technology in the field of substation active defense are proved and the effectiveness of the method is verified to realize the trust guarantee of the whole process of terminal access to intelligent substation.
