Secure Processors

Accord proposes a pioneering and innovative code-to-machine execution technology that preserves the encryption of executable instructions and data throughout all aspects of the execution cycle. At no time are instruction words or data values unencrypted. Crypto-reduced-instruction-processor-trusted-computers (CRIPTC) are not dependent upon reconfiguration or on machine uniqueness. CRIPTC memory and support chips are conventional. A CRIPTC machine has no standard functional units; each unit is synthesized by a crypto-synthesis compiler code builder combining aspects of cryptographic, very-long-instruction-word RISC compilers, hardware netlist synthesizers and chip place & route. The resulting CRIPTC instruction words form encrypted higher-level functional units. A 32-bit word has a key search space significantly greater than a 256-bit AES encryption. CRIPTC is a secure computer ideally suited to protecting critical technology in embedded real time or complex command and control processing. CRIPTC-based secure processing can be distributed outside secure sites, and applied within units which are subject to enemy capture. Accord will demonstrate a SystemC reference design that simulates bit-and-clock-accurate execution of the "never decrypted" CRIPTC instruction stream.
