Secure Processing Unit

Architecture

A Secure Processing Unit (SPU) is a specialized hardware component designed with an isolated execution environment to perform sensitive operations, such as cryptographic computations and key management. This architecture integrates tamper-resistant features and secure memory enclaves, physically separating critical processes from the general-purpose CPU. Its design minimizes the attack surface, providing a robust foundation for securing financial derivative transactions. Such units are vital for high-assurance applications.
