Hidayatullah Ahsan - Pullman WA, US

Assignee:

Schweitzer Engineering Laboratories, Inc. - Pullman WA

International Classification:

H04L 9/40
H04L 9/08

Abstract:

An intelligent electronic device (IED) of an electric power distribution system includes processing circuitry and a memory that includes a tangible, non-transitory, computer-readable comprising instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to receive operating data associated with the electric power distribution system, determine whether the operating data matches with expected operating data, generate a connectivity association key (CAK) based on the operating data in response to a determination that the operating data matches with the expected operating data, and establishing a connectivity association based on the CAK.

Assignee:

Schweitzer Engineering Laboratories, Inc. - Pullman WA

International Classification:

H04L 12/46
H04L 29/06
H04L 9/32

Abstract:

An intelligent electronic device (IED) of an electric power distribution system includes processing circuitry and a memory having instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to determine establishment of setup criteria to operate in a passive mode, operate in the passive mode to communicate data without initiation of a media access control security key agreement (MKA) protocol in response to determination of the establishment of the setup criteria, receive activation data during operation in the passive mode, the activation data being indicative that a media access control security (MACsec) communication link is to be established, and operate in an active mode in response to receipt of the activation data to initiate the MKA protocol to establish the MACsec communication link.

Inventors:

- Pullman WA, US
Colin Gordon - Katy TX, US

Assignee:

Schweitzer Engineering Laboratories, Inc. - Pullman WA

International Classification:

H02J 13/00
H04L 29/06

Abstract:

A control system of an electric power distribution system includes processing circuitry and a memory having instructions that, when executed by the processing circuitry, cause the processing circuitry to perform operations that include receiving an indication of a profile, generating a connectivity association key (CAK) based on the profile, distributing a copy of the CAK to a device of the electric power distribution system, and establishing a connectivity association with the device in accordance with the profile based on a verification that the device possesses the copy of the CAK.

Assignee:

Schweitzer Engineering Laboratories, Inc. - Pullman WA

International Classification:

H04L 29/06
H04W 84/12

Abstract:

An intelligent electronic device (IED) of an electric distribution system includes processing circuitry and a memory having instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to perform operations that include receiving an indication to establish a media access control security (MACsec) communication link in accordance with a confidential mode configured to block access to communication traffic associated with the MACsec communication link, indicating that the MACsec communication link is to be established in accordance with the confidential mode, receiving establishment of the MACsec communication link in accordance with the confidential mode, and communicating data via the MACsec communication link.

International Classification:

H04L 9/32
G06F 21/64
G06F 16/23

Abstract:

An intelligent electronic device (IED) of an electric power delivery system includes processing circuitry a memory that includes instructions. The instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to receive first data via parallel redundancy protocol (PRP), generate a first integrity check value using a media access control security (MACsec) integrity check function based on the first data, receive second data via PRP, generate a second integrity check value using the MACsec integrity function based on the second data, compare the first integrity check value and the second integrity check value with one another, and output a notification in response to determining that the first integrity check value and the second integrity check value do not match one another.

H04L 9/08
H02J 13/00

Abstract:

A non-transitory computer readable medium includes instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to operate in a recovery mode after initiating a startup operation, transmit a data frame to a device of an electric power delivery system during the recovery mode, the data frame indicating a request for a security association key (SAK), receive the SAK from the device in response to transmitting the data frame, and use the SAK to communicate data via a media access control security (MACsec) communication link.

Assignee:

Schweitzer Engineering Laboratories, Inc. - Pullman WA

International Classification:

G07C 9/00

Abstract:

Systems and methods are presented for managing physical access to an access-controlled area using a local access control system. In certain embodiments, information that may be used in access control determinations managed by a remote domain controller may be communicated to a local access control system for use in connection with local access control determinations performed by the access control system independent of the domain controller. In some embodiments, such a configuration may allow for access control determinations to be performed when communication with the domain controller is interrupted and/or otherwise limited.
