摘要:
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.
