AUTHENTICATION METHOD FOR DELIVERING INFORMATION IN SMART GRID SYSTEM AND INFORMATION COLLECTING METHOD IN SMART GRID SYSTEM

摘要

An authentication method for transferring information in a smart grid system includes the steps of a control server transmitting a policy for forming a hierarchical structure to a plurality of smart meters in a smart grid system, the plurality of smart meters belonging to the same group Wherein the control server is configured to generate a first key chain using a TESLA technique, wherein the upper layer smart meter is configured to communicate with the first key chain, Generating a seed key using an element and an arbitrary binary bit, and the upper layer smart meter generating a second key chain using the seed key as a start value using a TESLA technique.;
