A company deploys a secure device for advanced cryptography and physical tamper controls. They observe longer-than-expected processing times for numerous signing requests each day. Which method alleviates these delays while protecting the device’s key storage?
Enable parallel processing options on the secure device to handle cryptography simultaneously
Use unencrypted storage for private keys to reduce retrieval time
Increase the request time window so each operation finishes without error
Perform all cryptographic tasks on a server to offload workload from the secure device
Enabling parallel processing on the secure device allows multiple signing operations at once, preserving tamper protections and preventing key exposure. Offloading cryptographic tasks to a general-purpose system removes dedicated safeguards, storing keys unencrypted breaks core security principles, and extending time windows does not address the actual performance bottleneck.
