DID
Decentralized Identity / Self-Sovereign Identity for 6G
A privacy-preserving identity framework where users, autonomous vehicles, and IoT sensors hold cryptographic ownership of their identities without central carrier databases.
Technical Explanation
In traditional cellular systems, the telecom operator holds complete centralized control over subscriber identities (IMSI/SUPI stored in the HLR/UDM). 6G Decentralized Identity (DID), standardized by W3C, gives users, autonomous drones, and smart devices self-sovereign cryptographic control. Devices generate their own public/private key pairs and present cryptographically verifiable credentials (VCs) to base stations, authenticating network access without revealing personal identity or real-world names.
Key Functions
- Self-sovereign decentralized cryptographic identity for users, vehicles, and IoT sensors
- Zero centralized identity database vulnerabilities, eliminating mass data breaches
- User-controlled selective attribute disclosure (e.g., proving 'age > 18' without showing birthdate)
- Seamless cross-carrier and cross-border identity verification using distributed ledgers
- Native integration with W3C Verifiable Credentials and 3GPP Rel-19 security stacks
