Fingerprinting: Bounding the Soft-Error Detection Latency and Bandwidth
Fingerprinting summarizes the history of internal processor state updates into a cryptographic signature. The processors in a dual modular redundant pair periodically exchange and compare fingerprints to corroborate each other's correctness. relative to other techniques, fingerprinting offers superior error coverage and significantly reduces the error-detection latency and bandwidth.
