Zero-Knowledge Proofs

Technical Explanation

In smart cities and connected health applications, devices must prove authorizations without leaking citizen privacy. Zero-Knowledge Proofs (ZKPs, such as zk-SNARKs and Bulletproofs) allow a device to mathematically prove that a statement is true without revealing the secret behind it. A connected vehicle can prove to a municipal roadside unit that it has paid road taxes and is registered to drive in the zone without disclosing its owner's name, license plate, or home address.

Key Functions

• Proving identity, authorization, or attribute validity with zero private data leakage
• Compact mathematical proof generation (<500 bytes) with microsecond verification
• Privacy-preserving anonymous network slice access for healthcare and financial apps
• Proving location within a defined geographic perimeter without exposing exact GPS coordinates
• Standardized integration into W3C Verifiable Credentials and 3GPP identity protocols
