10     Conformity Assessment Steering Committee
The sixth meeting of the ITU-T Conformity Assessment Steering Committee (CASC) took place during ITU-T SG11 meeting on 20 July 2018.
IEC presented the draft Operational Document (OD) named "ICT Laboratory Recognition Service on ITU–T Recommendations" that is intended to be set up as a standalone service based on the IECEE CB scheme (SG11-C200). This document was prepared by IECEE TF as a concept and it specifies the requirements and processes of the ICT Laboratory Recognition Service based on ITU–T Recommendations. It was noted that the IECEE OD is in line with the ITU TL recognition procedure specified in the relevant Guideline on "Testing Laboratories recognition procedure" agreed by ITU-T SG11 in 2015.
The CASC decided to seek approval of the conceptual, draft, OD in IECEE first and then CASC will develop its own guideline which would refer to the OD accordingly to ensure the protection of IEC intellectual property.
Finally, CASC noted that to facilitate a joint process for assessment and recognition of laboratories between ITU and IECEE, the established TL recognition procedure will provide the Testing Laboratories with some unique key advantages. As two truly international organisations covering a large scope of products and services, ITU and IECEE support laboratories to have a harmonized process, which includes the scope of testing of both organisations. Such a harmonized process would allow laboratories to receive recognition from both organisations based on a single assessment per location. For large testing organizations as well as small test laboratories, this support an economical and optimized access to a larger testing portfolio based on their expertise and competence.
The OD is supposed to be adopted by IECEE CMC in 2019. The next ITU-T CASC meeting is scheduled on 8 March 2019 (planned).More details are available in CASC's report, in SG11-TD635/GEN.

19     Workshop "Global approaches on combating counterfeiting and stolen ICT devices", 23 July 2018.
ITU-T SG11 organized a Workshop on "Global approaches on combating counterfeiting and stolen ICT devices" which took place in Geneva on 23 July 2018.
One of the aims of the Workshop was to focus on concerns raised by ITU Member States during Council-18 on tampering with unique telecommunication device identifiers used in ICT devices such as IMEI.
The objectives of the Workshop were:

• tampering and duplication of IMEI identifiers used in mobile devices;
• key challenges faced by telecom operators, regulators and ICT vendors producing genuine end-devices, in using existing identifiers of ICT devices, including issues related to cloning, tampering and duplication of identifiers;
• identification systems, which are currently used for combating counterfeiting and stolen ICT devices, and discuss the importance of reliable unique ICT device identifiers for such tasks;
• identification systems, which guarantee that existing identifiers could be securely stored on devices and rendered tamper-proof, and implement means of detecting clones and differentiating them from genuine devices;
• action plan on developing possible technical solutions to address the problem of duplication/tampering/cloning of unique ICT device identifiers to be used for combating counterfeiting and stolen ICT devices;
• problems and impact of counterfeiting issues on ICT market, ranging from lost taxes and other revenue; erosion of brand value, network disruptions and interoperability challenges resulting in poor quality of service delivery; and risks to health, safety and environment;
• new trends and challenges in the combat of counterfeit and stolen ICT devices, including the tampering and/or duplication of unique device identifiers;
• mechanisms to secure the supply chain management (from manufacturing, importation distribution and marketing) to ensure traceability, security, privacy and trust of people, products and networks;
• technical solutions to combat counterfeit and stolen ICT devices;
• national/regional and global activities on combating counterfeiting and stolen ICT devices;
• SG11 activities on combating counterfeiting ICT devices and combating the use of stolen ICT devices.

​Two demo-zones were deployed at the Workshop to demonstrate technical solutions on combating counterfeiting and stolen ICT devices, which basic concepts were presented during the Workshop, as follows:

• IMEI-DOA solution to combat counterfeiting ICT devices, Rostelecom;
• Combat Mobile Device Theft with blockchain-based Global IMEI Storage and Services Innovation, Deutsche Telekom, SAP and Camelot ITLab.

​The event was attended by 68 participants from 32 Countries. More details are available on Workshop's web page. The outcomes of the Workshop can also be found in SG11-TD 560/GEN.
Following the results of the Workshop, ITU-T SG11 decided to request TSB Director to inform Council on the following:

• Study approaches on how to defend existing ICT identifiers against tampering/cloning of existing ICT identifiers;
• Draw up a list of unique ICT identifiers to be used for combating counterfeit and mobile device theft;
• Develop methods of assessing and verifying identifiers used for purposes of combating counterfeit and stolen devices;
• Consider Blockchain-based technologies to address the tampering/cloning of existing ICT identifiers, combat counterfeiting and stolen ICT devices;
• Develop mechanisms as appropriate for identifying counterfeit production.

​The presentations, video of the demo zones, interviews, newslog, photo and full list of actions agreed at the Workshop including the overview of the current situation are available in the outcomes posted on the Workshop's web page.

Finally, ITU-T SG11 would like to encourage all interested stakeholders (government, operators, device manufacturers, distributors, retailers) to join ITU-T SG11 for discussions on the approach to address cloning and tampering of existing identifiers, combat counterfeiting and stolen ICT devices."
