Abstract

A method for registering an intelligent electronic device (14) with a certification authority (16) comprises: enrolling a configuration tool (12) at the certification authority (16); generating a one-time password (28) for the intelligent electronic device (14) and storing the one-time password (28) in the certification authority (16) and in the configuration tool (20); connecting to the intelligent electronic device (14) with the configuration tool (20), wherein the configuration tool (20) authenticates at the intelligent electronic device (14); sending the one-time password (28) from the configuration tool (20) to the intelligent electronic device (14); enrolling the intelligent electronic device (14) at the certification authority (16) with the one-time password (28) and registering the intelligent electronic device (14) with the certification authority (16); and receiving a device certificate (34) from the certification authority (16) in the intelligent electronic device (14).

Description

technical field [0001] The present invention relates to a method, computer program and system for registering an intelligent electronic device with a certification authority. Background technique [0002] Cybersecurity requirements for utilities and so-called "smart grids" are becoming increasingly important. For example, the standard IEC (International Electrotechnical Commission) 62351-9 describes how keys, certificate enrollment, generation and revocation are to be managed in the automation industry. [0003] Digital (X.509) certificates are a form of digital identity. Digital certificates are used for several purposes, including authentication of users, processes, and devices. Therefore, it is important to perform certificate distribution securely. The challenge is to provide an efficient distribution process while also ensuring that no malicious IED receives a valid certificate. [0004] In order to ensure that only valid IEDs obtain valid credentials, the IED may n...
