ICCP-TASE.2 Update

IEC 60870-6-XXX TASE.2

TASE.2

- ICCP

 IEC 60870-6 TASE.2 Update underway within WG19

 Elimination of Unused Conformance Blocks by Making Them “Informative” instead of “Normative”  Block 6 – Programs

 Block 7 – Events

 Block 8 – Accounts

 Block 9 – Time Series

 Elimination of unused profiles (i.e. ISO/OSI transport/network)

 Integrating changes made since V2000-08 (Ed.2)  State Supplemental type

 Harmonization with CIM

 Objective is to enable CIM models from EMS to specify everything needed to configure ICCP links including secure ICCP parameters

 UML extensions for ICCP bilateral table information

 Reference to existing CIM standards for full, incremental and partial file formats for data exchange

 Herb Falk of SISCO is the editor

 Initial UML proposed. Work progressing

 ICCP-TASE.2 remains widely used for EMS real-time data exchange for high-voltage system security and power plant dispatch

 North America

 South America  Peru, Chile, Ecuador, Brazil, Colombia, etc.

 Pacifica  Australia and New Zealand

 Asia  India, Russia, Vietnam, Thailand, etc.

 New: Europe  ENTSO-E

 IEC 62351-3 – Use of TLS for encryption  IEC 62351-4 – Application Authentication for MMS based profiles

 IEC 61850

 IEC 60870-6 TASE.2 (ICCP)

 Recent attacks have reduced the effectiveness of some 1024-bit ciphers for encryption and some hash algorithms (SHA1) used for signing/authentication.

 An update to IEC 62351 will be started soon to deprecate these and officially increase asymmetrical key length options.

 1024-bit asymmetrical key length implementations are widely available today that can be used without the deprecated ciphers and hashes.

 Some products have already been updated for 2048-bit asymmetrical key length.

 Many products utilize multiple certificates per link to enable overlapping certificate expirations to support certificate updating with minimal impact on data transfers.

 Some products incorporate “secure fallback” mode:

 If a secure link cannot be established with a remote then the system will “fallback” to non-secure associations

 Secure ICCP products have been available since 1997.

 SCADA/EMS vendors have been working with it since 2003.

 Many systems have Secure ICCP licenses.

 Very few systems use Secure ICCP.

 The business processes to establish and maintain data flow using Secure ICCP are not overwhelming.

 Of course the government will make this all better when they write laws and regulations requiring it.

 Fear, uncertainty, and doubt should be added to the 7 deadly sins.

 SISCO is working with our OEM partners to migrate to a new code base for the underlying communications stack used for ICCP-TASE.2 communications.

 Driven by increased expectations from users for maintenance activities and increased expectations for performance, scalability and vulnerability.

 Elimination of Marben components and replaced with SISCO designed stack that is much much simpler and without some of the limitations.

 Base stack technology is used in hundreds of thousands of IEC 61850 devices and has been used in ICCP solutions since 2006.

 Will require new licenses and installation.

IEC 61850 IEC

 IEC 61850 Edition 1 was a new and innovative approach to substation automation:  Standardized Device and Object Modeling

 Logical Devices, Logical Nodes, Common Data Classes, etc.

 Extensions unique to specific applications (Hydro, Distributed Energy Resources (DER), Wind power, etc.)

 Standardized Service/Behavior Modeling

 Standardized XML for Systems and Device Configuration

 Standardized Communications Protocols for Specific Use Cases:

 Station Level Monitoring and Control (substation SCADA) (TCP/IP)

 Protection and Control – GOOSE over Ethernet

 Sampled Values – Process Bus over Ethernet

 Standardized Conformance Test Cases

 Much was learned using and testing Edition 1

 UCA International Users Group (UCAIug – http:///www.ucaiug.org) operated a technical issue (Tissue) resolution process for IEC 61850 as part of its Liaison D status with IEC.

 Anyone could enter a Tissue

 IEC committee experts would propose solution

 If consensus on solutions that affect interoperability, UCAIug made them mandatory for Edition 1 testing

 Otherwise, submitted to IEC for Edition 2

 New Common Data Classes

 New Abstract Modeling Approach for control blocks and Controls  Mapping of abstract models in IEC 61850-8-1 updated to result in nearly identical protocol on the wire  Backward compatible

 New and updated logical nodes

 More detailed state diagrams and service descriptions for reporting and control operations.

 All significant reporting changes were considered mandatory for Edition 1 and have been implemented already.

 Substation Configuration Language (IEC 61850-6)  Numerous changes to address changes to CDCs and LNs

 Edition 2 of IEC 61850 is renamed:

 IEC 61850-90-5 packets are encrypted.  Symmetric keys change periodically

 Next key to be used is included in the stream

Standardized configuration through the Substation Configuration Language
