Resumption efficiency measures how effectively a cryptographic operation can restart after an interruption, minimizing wasted computational effort and time. It quantifies the performance overhead associated with pausing and resuming a cryptographic process. Higher resumption efficiency indicates a more robust and practical cryptographic protocol, especially in environments prone to disconnections. This metric is critical for long-duration secure computations.
Context
The current focus is on optimizing cryptographic protocols, particularly in the context of resumable cryptography, to achieve higher resumption efficiency. A key debate involves designing protocols that can quickly and securely re-establish cryptographic state after an interruption. Future developments will include new algorithmic approaches and hardware accelerators to further improve the speed and resource utilization during the resumption of cryptographic operations.
A new cryptographic primitive, resumable ZKPoK, enables sequential proof sessions to be exponentially cheaper, unlocking efficient stateful post-quantum cryptography.
