Cloud Enclave Data Provisioning with Attestation and Session Keys

The patent applies dynamics by transitioning from static HSM capabilities to dynamic cloud-based enclave capabilities. The enclave can be flexibly configured and scaled based on actual security needs, allowing capabilities to adapt rather than being fixed at procurement time. This resolves the contradiction by enabling security to match actual requirements without over-provisioning expensive HSM hardware.

The patent uses copying by creating a virtual copy of HSM functionality within a cloud enclave. Instead of provisioning physical HSM hardware with fixed capabilities, the system copies the essential security functions into a virtualized environment that can be dynamically adjusted. This allows security functionality to be maintained while avoiding the high cost of over-provisioned physical HSM devices.

The dynamic nature of cloud enclaves allows capabilities to be scaled up or down based on actual workload demands. If latency or functionality issues arise, the enclave resources can be dynamically increased without replacing physical HSM hardware. This resolves the contradiction by enabling cost-effective operation at lower capacities with the option to scale up performance when needed.

The cloud enclave provides universal computing resources that can handle multiple different functionalities and workloads. Instead of requiring specialized HSM hardware for each function, the enclave can be configured to perform various cryptographic operations, data processing tasks, and security functions. This multi-functionality allows reduced capability HSMs to suffice while maintaining productivity through flexible resource allocation.

The patent applies preliminary action by performing attestation verification before data provisioning. The HSM verifies the enclave's identity and trustworthiness in advance through cryptographic attestation mechanisms. Only after successful verification does the system proceed to provision sensitive data. This preliminary security check maintains ease of operation while preventing eavesdropping and unauthorized access.

The patent uses an intermediary approach by introducing cryptographic attestation as a mediator between the HSM and the enclave. Rather than directly provisioning data based on trust, the system uses attestation certificates and cryptographic verification as an intermediary layer. This mediator ensures security while maintaining operational simplicity, as the verification process is automated and does not require manual intervention.

The patent applies self-service by enabling the enclave to autonomously generate and provide its own attestation credentials. The enclave performs self-verification by presenting cryptographic proofs of its identity and integrity. The HSM automatically verifies these credentials without requiring manual configuration or complex verification protocols. This self-service approach maintains high security while reducing operational complexity.

The patent uses feedback mechanisms where the enclave continuously provides attestation information and cryptographic proofs to the HSM. The HSM verifies this feedback and adjusts data provisioning decisions accordingly. This automated feedback loop ensures security through continuous verification while simplifying the provisioning process, as the system automatically handles verification and key exchange without manual intervention.
