Summary of EU-China Joint White Paper on Internet-of-Things Identification

Core Content

This document, published on 31/10/2014, is a collaborative effort between IoT experts from the European Union and China, under the EU-China IoT Advisory Group. It aims to document the current state of IoT identification technologies in both regions and provide an outlook for future developments. The paper outlines the key concepts, technologies, and challenges related to IoT identification, and offers development guidelines to improve interoperability, security, and scalability.

Main Points

1. IoT Identification Concepts

IoT involves the interconnection of uniquely identifiable objects using internet technologies.
Identification is essential for the development and operation of IoT applications and services.
Identification mechanisms are required for both physical objects and virtual/logical entities.
Physical objects are identified using identifiers like IP addresses, hostnames, or URIs.
Logical objects are identified using technologies like DOIs, URIs, and URLs.

2. Taxonomy of IoT Identifiers

Object Identifiers (Object IDs): Used to uniquely identify physical or virtual objects. Examples include EPC, UPC, UUID, MAC, CID, and OID.
Communication Identifiers (Communication IDs): Used to uniquely identify devices in communication. Examples include IPv4, IPv6, and E.164.
Application Identifiers (Application IDs): Used to identify IoT applications or services. Examples include URIs and URLs.

3. IoT Identification Technologies

IoT ID Naming: Involves assigning and registering names to objects via naming/directory services.
IoT ID Addressing: Maps names to identifiers, enabling communication and location tracking.
IoT ID Discovery: Enables locating and retrieving IoT resources (e.g., services, data) through directory services.

4. Application Areas

Energy Management: Uses IPv6 and RFID for smart metering and grid management.
Supply Chain Management (SCM): Relies on UPC, EPC, and RFID for tracking and traceability.
Urban Mobility: Utilizes IoT ID technologies for smart parking, traffic control, and transportation systems.
Defense and Intelligence: Uses geospatial data and OGC standards (e.g., WMS, WFS) for asset tracking and contextual placement.

Key Technologies in China and EU

China

EPC (Electronic Product Code): Widely used for identifying physical objects, especially in logistics and M2M applications.
CID (Communication Identifier): A public IoT ID naming system developed by the China Academy of Telecommunication Research (CATR).
- CID consists of three parts: Compatibility Domain, Type Domain, and Information Domain.
- Compatibility Domain includes 8-bit COC (Country/Organization Code) and 8-bit NSC (Naming System Code).
- Type Domain includes 4-bit CT (Coding Type), 4-bit RT (Resource Type), and 8-bit BT (Business Type).
- Information Domain contains detailed information such as identity and attributes.
Ecode (Entity Code): A flexible coding system proposed by ANCC (Article Numbering Center of China).
- Ecode identifiers vary by Version (V), with different lengths and code types (binary, decimal, Unicode).
- The structure includes Version, Numbering System Identifier (NSI), and Master Data (MD).

EU

IPv6: Widely used for communication identifiers, especially in smart energy applications.
Handle/DOI: Used for object and application identification, enabling secure access and resolution.
DNS-SD (Domain Name System – Service Discovery): Supports service discovery in IoT applications.
Semantic Web Technologies: Used for enhancing interoperability and data integration in IoT.

Challenges and Solutions

Challenges

Interoperability: Integrating heterogeneous identification systems remains a challenge.
Scalability: Existing naming and addressing infrastructures may not support large-scale IoT deployments.
Security: Ensuring secure and authenticated access to identifiers and their attributes is critical.
Mobility Support: Addressing the need for mobility in IoT environments.
National Infrastructures: Different countries and organizations have their own ID systems, complicating cross-border interoperability.

Solutions and Developments

China: Has made progress in developing CID and Ecode systems, with focus on secure access, business type specification, and scalability.
EU: The IERC (Internet-of-Things Research Cluster) has been working on integrating naming and addressing systems, enhancing semantic interoperability, and improving security services.

Outlook and Development Guidelines

IPv6 Expansion: IPv6 is expected to play a central role in future IoT communication due to its large address space and support for robust networking.
Web Access: Integration of IoT ID functionalities into web-based systems is a recommended direction.
Semantic Web Validation: Testing and validating semantic web technologies for large-scale IoT deployments.
Mobility Handling: Developing techniques to support mobile IoT applications in discovery processes.
Unified Querying Services: Creating IoT unified querying services to improve cross-system identification and resource discovery.

Conclusion

The paper highlights the importance of a unified and interoperable IoT identification framework. It emphasizes the need for addressing the challenges of integration, security, and scalability, and suggests the development of standardized and secure identification solutions. Both China and the EU are actively working on such solutions, with China focusing on CID and Ecode, and the EU emphasizing IPv6, Handle/DOI, and Semantic Web technologies.
