EVOKE: Efficient Revocation of Verifiable Credentials in IoT Networks

Watch a 12-minute conference presentation from USENIX Security '24 exploring EVOKE, a novel mechanism for efficient revocation of Verifiable Credentials in IoT networks. Learn how researchers from the University of Bologna and Florida International University address trust challenges in IoT device collaboration through an innovative ECC-based accumulator system. Discover how EVOKE overcomes limitations of traditional Public Key Infrastructure by enabling decentralized authentication while minimizing computing and storage requirements for resource-constrained IoT devices. Examine experimental results demonstrating EVOKE's practical advantages, including its ability to maintain verification information with just 1.5KB of storage - half that of PKI certificates - and achieve rapid network updates even with 50% of devices offline. Gain insights into how this solution aligns with W3C and EU standards while enabling mass revocation capabilities and millisecond-level latency across hybrid IoT networks.
