Mass authentication information injection method for effective security management of AMI device

Abstract

AMI is a technology that provides electricity usage and billing information in real time by two-way communication between consumers and a supplier which is a power company. The two-way communication environment can be used as a variety of security threat paths and security vulnerabilities may occur due to the increased adoption of multi-devices by multiple manufacturers. Security threats to AMI can be a major threat to cybersecurity across the country, so countermeasures are needed. In order to solve these problems, an electronic certificate-based AMI device authentication system was established, but a system for managing and injecting keys and certificates for a large number of devices is required. Management technology for security authentication information such as keys and certificates of AMI devices is an important factor in ensuring AMI security safety. Therefore, in this paper, we propose a method to inject mass security authentication information for AMI devices to systematically, effectively manage and safely inject authentication information.
