A cryptographic protocol to provide integrity with optional confidentiality for cyber security of substation serial links is defined in this standard. It does not address specific applications or hardware implementations and is independent of the underlying communications protocol.The elevated concern of cyber security throughout the power industry has created a need to protect communications to and from substations. This standard defines a cryptographic protocol known as Secure SCADA Communications Protocol (SSCP) that protects the integrity and, optionally, the confidentiality of asynchronous serial communications typically used by control system equipment. SSCP is primarily intended to protect serial SCADA communications, but can be applied to other serial communications, such as the maintenance ports of intelligent electronic devices. SSCP is independent of the underlying communications link and protocol (e.g., Modbus, DNP3, IEC 60870- 5), and is appropriate for serial communications over leased lines, dial-up lines, multi-drop links, radio, power line carrier, fiber optic, etc. SSCP is suitable for implementation in new equipment or for deployment in bump-in-the-wire devices retrofitting protection to existing systems.

Other Activities From This Working Group
Current projects that have been authorized by the IEEE SA Standards Board to develop a standard.
No Active Projects
Standards approved by the IEEE SA Standards Board that are within the 10-year lifecycle.
No Active Standards
These standards have been replaced with a revised version of the standard, or by a compilation of the original active standard and all its existing amendments, corrigenda, and errata.
No Superseded Standards
These standards have been removed from active status through a ballot where the standard is made inactive as a consensus decision of a balloting group.
No Inactive-Withdrawn Standards
These standards are removed from active status through an administrative process for standards that have not undergone a revision process within 10 years.
No Inactive-Reserved Standards
