The Design of Information Security System for Digital Power Grid

Digital power grid (DPG) is a highly informatized systems with multi-level and multi-area. According to the features of DPG, a information security system is presented with its key functions. The design adopts master-slave mode to implement security policy. 2-layer encryption mechanism is proposed to guarantee information security and integrity. The license structure based on XML can strengthen the flexibility of information security policies and the extensibility of information rights.
