Accelerator Trustworthiness via Secure Communication

The patent applies preliminary action by performing authentication and encryption setup before the accelerator processes workloads. The host system and accelerator establish secure communication channels, exchange cryptographic keys, and verify identities in advance. This preliminary security configuration ensures that when the accelerator processes sensitive computations in shared environments, the trustworthiness is already established, preventing malicious tampering while maintaining high productivity.

The patent introduces cryptographic protocols and authentication mechanisms as intermediaries between the host system and accelerator. These intermediary security layers verify the authenticity of workloads, inputs, and outputs without directly interfering with the accelerator's computational performance. The intermediary authentication process acts as a trusted mediator that guarantees trustworthiness while allowing the accelerator to maintain its high productivity in shared environments.

The patent minimizes time loss by performing authentication and key exchange operations in advance, before the actual computational workload is executed. The host system and accelerator establish secure communication channels and verify identities beforehand, so that during the actual computation, the security checks do not repeatedly interrupt the processing flow. This preliminary action ensures data integrity while reducing the impact of authentication overhead on total processing time.

The patent applies partial action by implementing authentication and encryption only for critical data paths and sensitive operations, rather than uniformly applying full security protocols to all communications. This selective approach maintains data integrity for essential workloads while reducing the overall communication overhead and processing time penalty associated with comprehensive authentication and encryption for every operation.

The patent reduces energy consumption by establishing secure communication channels and performing cryptographic key exchange in advance, before the accelerator executes energy-intensive computational workloads. The preliminary security setup ensures protection against malicious activities, while the actual computation phase can proceed with minimal additional cryptographic overhead, thus reducing the total energy consumption compared to continuous encryption during computation.

The patent applies partial action by implementing strong encryption and authentication only for data transmission between host and accelerator, while using lighter security mechanisms or cached credentials during the accelerator's internal processing. This selective security approach protects against external malicious activities while minimizing the computational and energy overhead during the actual workload execution.
