Abstract: Systems and methods are disclosed herein relating to the secure configuration of intelligent electronic devices. Intelligent electronic devices are used in electric power generation and transmission systems for protection, control, automation, and/or monitoring of equipment. The use of tokens and token-based digital signatures in the configuration process of intelligent electronic devices reduces the likelihood of malicious acts or unintended errors. Tokens distributed to engineers, technicians, intelligent electronic devices, computing devices, and/or software decrease the likelihood of errors being introduced in the configuration process.

Abstract: The present disclosure pertains to systems and methods of restricting access to devices utilizing tokens. In some embodiments, a system may include a user requesting a token, ensuring the user requesting a token has the permission to request the token and is not the user approving the token. In some embodiments, the system may include the user granting the token, wherein the user granting the token is not the user receiving the token. The system ensures that the user accessing the device has the permission to access the device. Additionally, the system decreases the opportunities for insider attacks and increases the resistance to credential theft attacks. Further, the system increases the accountability for changes and the ability to review changes.

Abstract: Systems and methods are described herein for token-based access to an intelligent electronic device (IED) resource in a power delivery system. A token server and an IED resource may be communicatively connected via a communication network. The token server may generate a token associated with access privileges to one or more IED resources. The token server associates an access duration time with the generated token. The user presents the IED resource with the token as part of an access attempt. The IED resource grants access at a first time defined with reference to the device uptime of the IED resource until a second time defined with reference to the device up time. The difference between the first time and the second time corresponds to the access duration time of the token.
