This invention discloses a method for measuring the integrity of a spaceborne embedded system based on link symbol topology. In the static injection phase, a linker script is configured to inject symbols at critical memory segment boundaries, generating hierarchical hybrid fingerprints and redundantly persisting them to non-volatile storage. In the dynamic verification phase, a lightweight program is started before the operating system takes over, performing hierarchical dual-dimensional and SEU-resistant temporal redundancy verification, supporting multi-container dedicated isolation verification. In the linkage blocking phase, anomalies are forcibly blocked and primary / backup linkage is triggered, collecting eight types of fault contexts and supporting on-orbit updates. This invention solves the problems of traditional hash methods failing to detect layout anomalies and high time consumption, reducing complexity to O(K), achieving sub-millisecond-level measurement decoupled from image volume, adapting to spaceborne radiation-resistant, cloud-native, and redundancy scenarios, and meeting the high reliability requirements of aerospace.

Systems and methods for mathematical modeling of the hardware and software stack of commodity computer platforms are provided, enabling provable guarantees on memory, device, and program execution. This approach addresses the technical problem of reliance on system agents that rely on implicit trust in the operating environment, which can be exploited by sophisticated attackers using complex threats such as memory access exploits and code / data integrity exploits. The solution provides a proactive, mathematically-backed security solution that eliminates entire classes of cyberattacks by design, ensuring realizable guarantees on commodity computer platforms running hardware and software stack elements at the lowest operating level. This approach has significant advantages over current reactive cybersecurity methods, including reduced complexity and overhead, and increased confidence in the integrity of the system. The solution's main uses include providing mathematically-backed security and availability guarantees for critical infrastructure, financial institutions, and other organizations vulnerable to cyberattacks.

Embodiments described herein include a system, apparatus, article of manufacture, method and / or computer program product embodiments, and / or combinations and sub-combinations thereof, for delay-based physical unclonable functions (PUFs) for chiplets to verify system integrity. A die may include a plurality of chiplets including a first chiplet and a second chiplet. The first chiplet may be connected to the second chiplet via an interposer. As part of an authentication process, the first chiplet may request the second chiplet to transmit a signal via one or more wires of the interposer. A first signature based on the characteristics of the transmitted signal may be measured at a first time, which constitutes the first evaluation of the PUF. The first signature may be used as a baseline comparison for subsequent signatures as a means to confirm that the chiplets, interposers, and / or interconnects have not been altered or modified.

Systems and methods for seamless network communication reconfiguration, comprising a device that includes physical media dependent (PMD) devices, incorporating a digital signal processor (DSP) configured to handle both in-band and out-of-band communication traffic, a plurality of primary analog crossbars connected to the DSPs for routing operational data, and a set of redundant analog crossbars configured to establish auxiliary communication channels. The system includes a controller operable to dynamically activate the auxiliary communication channels during reconfiguration events, enabling a make-before-break protocol by transitioning traffic from primary channels to auxiliary channels. The redundant crossbars support out-of-band signaling to coordinate transitions and maintain system integrity. The auxiliary channels remain in a low-power state during steady operation, ensuring resource efficiency, while the controller monitors signal integrity and initiates reconfiguration upon detecting a fault or network event, maintaining uninterrupted traffic flow.

A constraint-driven trust state orchestration system intercepts proposed actions at execution boundaries prior to execution, deterministically evaluates trust states against constraints, enforces execution exclusively based on cryptographically verifiable qualification outcomes, and immutably records all decisions and outcomes to ensure consistency, auditability, reduced rollback costs, and improved system integrity across distributed decision networks.
