Safety- critical applications would only use assured enclaves, reducing the need for recertification. The assured enclaves can then be protected by multiple layers of security that would require an adversary to break through all layers to gain a foothold. Furthermore, if the subsystem is deployed in special environments requiring ruggedization, such as radiation hardening, only those critical enclaves would need to be hardened and others just tolerant. This architectural approach is easier to build and maintain, and paves the path to safe and secure systems. As a leading provider of rugged, safe and secure subsystems, Mercury has experience designing and implementing isolated architectures and works closely with customers to design solutions that meet specific application requirements. A segmented architecture would have a secure, assured processing enclave that contains management software. This software would limit the access of each non-critical processing enclave to minimize attack surfaces, while the critical enclave would be assured and contain all safety-critical functions.
