Hardware security module for relocating cryptographic instructions
The patent US12069171B2 describes a hardware security module (HSM) designed to enhance the efficiency and security of cryptographic operations. The HSM includes a receiver for instructions and a control device that manages an instruction queue. When the instruction load exceeds a specified threshold, the control device identifies a second HSM for instruction relocation, authenticates it, and requests the processing of the instructions. The control device can also configure the second HSM, clone its configuration, and communicate via a peer-to-peer link. This system allows for dynamic load balancing and ensures that the instruction load remains manageable.
Additionally, the patent outlines methods for operating the HSM, including monitoring the instruction queue and relocating instructions based on load. It emphasizes security measures, such as detecting unauthorized access and deleting sensitive information if a breach is suspected. The control device can also implement a secret-sharing principle for communication and ensure that cryptographic keys are protected through hardware-based measures. The instructions can be redundantly stored across multiple HSMs, enhancing reliability and security. Overall, the patent presents a comprehensive approach to managing cryptographic operations while maintaining high security standards.
