THE CHALLENGE
The core challenge for businesses operating in large-scale digital ecosystems such as cloud services, IoT networks, and virtual platforms is how to efficiently and reliably revoke digital credentials at scale without slowing down operations or overburdening devices. Traditional methods like Certificate Revocation Lists and the Online Certificate Status Protocol create bottlenecks as they grow with the number of revoked credentials, leading to high storage and bandwidth costs, increased latency, and reduced reliability in offline or low-connectivity settings. These limitations can impact user experience, introduce security vulnerabilities, and raise operational costs. As ecosystems expand to millions or even billions of credentials, companies need revocation mechanisms that are not only fast and scalable but also lightweight enough to run on constrained devices while ensuring real-time validation without constant reliance on central servers.
OUR SOLUTION
We offer replacement of bulky Certificate Revocation Lists and latency-prone OCSP checks with a global binary bitmap in which each credential is assigned a sequential serial number that directly indexes a bit managed by a central server which can deliver a compact, fast, and resilient credential status framework, ideally suited for large-scale digital ecosystems such as IoT networks, virtual platforms, and metaverse environments. The server compresses the inherently sparse bitmap, While Clients decompress the bitmap, and perform a constant-time lookup to verify validity without bulky revocation lists or online queries. The approach stands out for its scalability and efficiency. Leveraging a fixed-length sparse bitmap yields high compression when revocations are rare, while constant-time (O(1)) lookups far outperform traditional CRL or OCSP methods. Distributing a single compressed snapshot minimizes bandwidth and server load, and local bitmap storage enables offline verification.
