METHOD FOR GENERATING A KEY KEY AND MANAGING THEM FOR A MODEL OF TYPICAL OBJECT-ORIENTED EVENTS (SUBSTATIONS)

摘要

1. A method for distributing a dedicated group key in systems using Typical Object Oriented Substation Events (GOOSE), comprising: determining a group configuration for a GOOSE system through its set of components, consisting of field devices, checking that each field device in the group has a pair of asymmetric keys , the distribution of the group key individually to each field device of a group member by the substation controller through the secure interaction between the substation controller and the field troystvom group member, the group key and updating changes after gruppy.2 configuration. A method for distributing a dedicated group key according to claim 1, wherein the pair of asymmetric keys is one of a certificate or a public key and a corresponding private key. A method for distributing a dedicated group key according to claim 2, wherein said certificate serial number is used to establish group membership. The method for distributing a selected group key according to claim 1, wherein distributing the group key individually to each field device of the group member by the substation controller through a secure interaction between the substation controller and the group member device contains asymmetric encryption by means of a public key for each field device. The method for distributing a selected group key according to claim 1, wherein distributing the group key individually to each field device of the group member by the substation controller through a secure interaction between the substation controller and the group member device contains
