DOD-I-5200.44 requires the following:
4.c.2 “Control the quality, configuration, and security of software, firmware, hardware, and systems throughout their lifecycles... Employ protections that manage risk in the supply chain… (e.g., integrated circuits, field-programmable gate arrays (FPGA), printed circuit boards) when they are identifiable (to the supplier) as having a DOD end-use. “ 4.e “In applicable systems, integrated circuit-related products and services shall be procured from a Trusted supplier accredited by the Defense Microelectronics Activity (DMEA) when they are custom-designed, custommanufactured, or tailored for a specific DOD military end use (generally referred to as application-specific integrated circuits (ASIC)). “ 1.g “In coordination with the DOD CIO, the Director, Defense Intelligence Agency (DIA), and the Heads of the DOD Components, develop a strategy for managing risk in the supply chain for integrated circuit-related products and services (e.g., FPGAs, printed circuit boards) that are identifiable to the supplier as specifically created or modified for DOD (e.g., military temperature range, radiation hardened).

The [organization] shall ensure that the contractors/developers have all ASICs designed, developed, manufactured, packaged, and tested by suppliers with a Defense Microelectronics Activity (DMEA) Trust accreditation.{SV-SP-5}{SR-1,SR-5}
|
|
The [organization] shall ensure that the contractors/developers have all EEEE, and mechanical piece parts procured from the Original Component Manufacturer (OCM) or their authorized franchised distribution network.{SV-SP-5}{SR-1,SR-5}
|
These requirements might only make sense for ASIC/FPGA that are deemed to support mission critical functions. The Program has the responsibility to identify all ASICs and FPGAs that are used in all flight hardware by each hardware element. This list must include all contractor and subcontractor usage of ASICs and FPGAs.
|
The [organization] shall use a DMEA certified environment to develop, code and test executable software (firmware or bit-stream) that will be programmed into a one-time programmable FPGA or be programmed into non-volatile memory (NVRAM) that the FPGA executes.{SV-SP-5}{SR-1,SR-5}

4.c.2 “Control the quality, configuration, and security of software, firmware, hardware, and systems throughout their lifecycles... Employ protections that manage risk in the supply chain… (e.g., integrated circuits, field-programmable gate arrays (FPGA), printed circuit boards) when they are identifiable (to the supplier) as having a DOD end-use. “ 4.e “In applicable systems, integrated circuit-related products and services shall be procured from a Trusted supplier accredited by the Defense Microelectronics Activity (DMEA) when they are custom-designed, custommanufactured, or tailored for a specific DOD military end use (generally referred to as application-specific integrated circuits (ASIC)). “ 1.g “In coordination with the DOD CIO, the Director, Defense Intelligence Agency (DIA), and the Heads of the DOD Components, develop a strategy for managing risk in the supply chain for integrated circuit-related products and services (e.g., FPGAs, printed circuit boards) that are identifiable to the supplier as specifically created or modified for DOD (e.g., military temperature range, radiation hardened).

The [organization] should have requirements/controls for all ground/terrestrial systems covering: Data Protection, Ground Software, Endpoints, Networks, Computer Network Defense / Incident Response, Perimeter Security, Physical Controls, and Prevention Program (SSP, PPP, and Training).See NIST 800-53 and CNSSI 1253 for guidance on ground security {SV-MA-7}

|
The [organization] shall ensure reused TT&C software has adequate uniqueness for command decoders/dictionaries so that commands are received by only the intended satellite.{SV-SP-6}{AC-17(10),SC-16(3),SI-3(9)}
|
The goal is to eliminate risk that compromise of one command database does not affect a different one due to reuse. The intent is to ensure that one SV can not process the commands from another SV. Given the crypto setup with keys and VCC needing to match, this requirement may be inherently met as a result of using type-1 cryptography. The intent is not to recreate entire command dictionaries but have enough uniqueness in place that it prevents a SV from receiving a rogue command. As long as there is some uniqueness at the receiving end of the commands, that is adequate.
|
The [spacecraft] shall protect authenticator content from unauthorized disclosure and modification.{SV-AC-1,SV-AC-3}{AC-17(6),CM-3(6),IA-5,IA-5(6),RA-5(4),SA-8(18),SA-8(19),SC-28(3)}

The [spacecraft] encryption key handling shall be handled outside of the onboard software and protected using cryptography.{SV-AC-1,SV-AC-3}{AC-17(6),CM-3(6),SA-8(19),SA-9(6),SC-8(1),SC-12,SC-28(1),SC-28(3)}
|
|
The [spacecraft] encryption keys shall be restricted so that the onboard software is not able to access the information for key readout.{SV-AC-1,SV-AC-3}{AC-17(6),CM-3(6),SA-8(19),SA-9(6),SC-8(1),SC-12,SC-28(3)}
|
|
The [spacecraft] encryption keys shall be restricted so that they cannot be read via any telecommands.{SV-AC-1,SV-AC-3}{AC-17(6),CM-3(6),SA-8(19),SA-9(6),SC-8(1),SC-12,SC-28(3)}

|
The [spacecraft] software subsystems shall provide two independent and unique command messages to deactivate a fault tolerant capability for a critical or catastrophic hazard.{SV-MA-3,SV-AV-7}{AC-3(2)}
|
|
The [spacecraft] shall use automated mechanisms to maintain and validate baseline configuration to ensure the [spacecraft] is up-to-date, complete, accurate, and readily available.{SV-SP-3}{CM-2(2),CM-3(5),CM-3(7),CM-6,SA-8(8)}
|
This could be command trigger from Ground or elsewhere. The point here is that the self-test is executed onboard the spacecraft via onboard HW/SW self-test mechanisms and its result is reported to the Ground
|
The [spacecraft] shall prevent the installation of Flight Software without verification that the component has been digitally signed using a certificate that is recognized and approved by the ground.{SV-SP-1,SV-SP-3,SV-SP-6,SV-SP-9}{CM-3,CM-3(8),CM-5,CM-5(3),CM-14,SA-8(8),SA-8(31),SA-10(2),SI-3,SI-7(12),SI-7(15)}
|
|
The [organization] shall ensure that software planned for reuse meets the fit, form, and function, and security as a component within the new application.{SV-SP-6,SV-SP-7,SV-SP-11}{CM-7(5)}
|
|
The [spacecraft] shall enter a cyber-safe mode when conditions that threaten the platform are detected, enters a cyber-safe mode of operation with restrictions as defined based on the cyber-safe mode.{SV-AV-5,SV-AV-6,SV-AV-7}{CP-10(6),CP-12,CP-13,IR-4,IR-4(1),IR-4(3),PE-10,RA-10,SA-8(16),SA-8(21),SA-8(24),SI-3,SI-4(7),SI-13,SI-17}
|
|
The [spacecraft] shall provide the capability to enter the platform into a known good, operational cyber-safe mode from a tamper-resistant, configuration-controlled (“gold”) image that is authenticated as coming from an acceptable supplier, and has its integrity verified.{SV-AV-5,SV-AV-6,SV-AV-7}{CP-10(6),CP-12,CP-13,IR-4(3),SA-8(16),SA-8(19),SA-8(21),SA-8(24),SI-13,SI-17}
|
Cyber-safe mode is an operating mode of a spacecraft during which all nonessential systems are shut down and the spacecraft is placed in a known good state using validated software and configuration settings. Within cyber-safe mode authentication and encryption should still be enabled. The spacecraft should be capable of reconstituting firmware and SW functions to preattack levels to allow for the recovery of functional capabilities. This can be performed by self-healing, or the healing can be aided from the ground. However, the spacecraft needs to have the capability to replan, based on available equipment still available after a cyberattack. The goal is for the vehicle to resume full mission operations. If not possible, a reduced level of mission capability should be achieved.
|
The [spacecraft] shall fail to a known secure state for failures during initialization, and aborts preserving information necessary to return to operations in failure.{SV-AV-5,SV-AV-6,SV-AV-7}{CP-10(6),CP-13,SA-8(16),SA-8(19),SA-8(24),SC-24,SI-13,SI-17}

The [spacecraft] shall provide or support the capability for recovery and reconstitution to a known state after a disruption, compromise, or failure.{SV-AV-5,SV-AV-6,SV-AV-7}{CP-4(4),CP-10,CP-10(4),CP-10(6),CP-13,IR-4,IR-4(1),SA-8(16),SA-8(19),SA-8(24)}
|
|
The [spacecraft] shall implement cryptography for the indicated uses using the indicated protocols, algorithms, and mechanisms, in accordance with applicable federal laws, Executive Orders, directives, policies, regulations, and standards: [NSA- certified or approved cryptography for protection of classified information, FIPS-validated cryptography for the provision of hashing].{SV-AC-1,SV-AC-2,SV-CF-1,SV-CF-2,SV-AC-3}{IA-7,SC-13}
|
|
The [spacecraft] shall generate error messages that provide information necessary for corrective actions without revealing information that could be exploited by adversaries.{SV-AV-5,SV-AV-6,SV-AV-7}{RA-5(4),SI-4(12),SI-11}
|
|
The [spacecraft] shall reveal error messages only to operations personnel monitoring the telemetry.{SV-AV-5,SV-AV-6,SV-AV-7}{RA-5(4),SI-4(12),SI-11}
|
|
The [spacecraft] boot firmware must validate the boot loader, boot configuration file, and operating system image, in that order, against their respective signatures.{SV-IT-3}{SA-8(10),SA-8(11),SA-8(12),SI-7(9),SI-7(10)}
|
A signature is ~770 bits long. No requirement is imposed on the storage location of signatures.
|
The [spacecraft] boot firmware must verify a trust chain that extends through the hardware root of trust, boot loader, boot configuration file, and operating system image, in that order.{SV-IT-3}{SA-8(10),SA-8(11),SA-8(12),SI-7(9),SI-7(10)}
|
These three items were chosen because they’re intended to be static values (once properly set up) but are in volatile storage. Also, the Boot ROM can’t be modified, so there’s no reason to check a signature.
|
The [spacecraft] shall perform attestation at each stage of startup and ensure overall trusted boot regime (i.e., root of trust).{SV-IT-3}{SA-8(10),SA-8(11),SA-8(12),SI-7(9),SI-7(10),SI-7(17)}
|
It is important for the computing module to be able to access a set of functions and commands that it trusts; that is, that it knows to be true. This concept is referred to as root of trust (RoT) and should be included in the spacecraft design. With RoT, a device can always be trusted to operate as expected. RoT functions, such as verifying the device’s own code and configuration, must be implemented in secure hardware (i.e., field programmable gate arrays). By checking the security of each stage of power-up, RoT devices form the first link in a chain of trust that protects the spacecraft
|
The [organization] shall use NIST Approved for symmetric key management for Unclassified systems; NSA Approved or stronger symmetric key management technology for Classified systems.{SV-AC-1,SV-AC-3}{SC-12,SC-12(1),SC-12(2)}
|
FIPS-complaint technology used by the Program shall include (but is not limited to) cryptographic key generation algorithms or key distribution techniques that are either a) specified in a FIPS, or b) adopted in a FIPS and specified either in an appendix to the FIPS or in a document referenced by the FIPS.

|
|
The [spacecraft] shall produce, control, and distribute asymmetric cryptographic keys using [organization]-defined asymmetric key management processes.{SV-AC-1,SV-AC-3}{SC-12,SC-12(1),SC-12(3)}
|
In most cased the Program will leverage NSA-approved key management technology and processes.

The [spacecraft] software subsystems shall provide independent mission/cyber critical threads such that any one credible event will not corrupt another mission/cyber critical thread.{SV-MA-3,SV-AV-7}{SC-3}
|
|
The [spacecraft] software subsystems shall accept [Program defined hazardous] commands only when prerequisite checks are satisfied.{SV-MA-3,SV-AV-7}{SI-10}
|
|
The [spacecraft] software subsystems shall identify and reject commands received out-of-sequence when the out-of-sequence commands can cause a hazard/failure or degrade the control of a hazard or mission.{SV-MA-3,SV-AV-7}{SI-10}
|
|
The [spacecraft] software subsystems shall perform prerequisite checks for the execution of hazardous commands.{SV-MA-3,SV-AV-7}{SI-10}
|
|
The [spacecraft] software subsystems shall discriminate between valid and invalid input into the software and rejects invalid input.{SV-MA-3,SV-AV-7}{SI-10,SI-10(3)}
|
|
The [spacecraft] software subsystems shall properly handle spurious input and missing data.{SV-MA-3,SV-AV-7}{SI-10,SI-10(3)}
|
|
The [spacecraft] software subsystems shall validate a functionally independent parameter prior to the issuance of any sequence that could remove an inhibit or perform a hazardous action.{SV-MA-3,SV-AV-7}{SI-10(3)}
|
|
The [spacecraft] mission/cyber critical commands shall be "complex" and/or diverse from other commands so that a single bit flip could not transform a benign command into a hazardous command.{SV-MA-3,SV-AV-7}{SI-10(5)}
|
|
The [spacecraft] software subsystems shall provide at least one independent command for each operator-initiated action used to shut down a function leading to or reducing the control of a hazard.{SV-MA-3,SV-AV-7}{SI-10(5)}
|
|
The [spacecraft] shall have failure tolerance on sensors used by software to make mission-critical decisions.{SV-MA-3,SV-AV-7}{SI-13,SI-17}
|
|
The [spacecraft] cyber-safe mode software/configuration should be stored onboard the spacecraft in memory with hardware-based controls and should not be modifiable.{SV-AV-5,SV-AV-6,SV-AV-7}{SI-17}
|
Cyber-safe mode is using a fail-secure mentality where if there is a malfunction that the spacecraft goes into a fail-secure state where cyber protections like authentication and encryption are still employed (instead of bypassed) and the spacecraft can be restored by authorized commands. The cyber-safe mode should be stored in a high integrity location of the on-board SV so that it cannot be modified by attackers.
|
The [spacecraft] software subsystems shall detect and recover/transition from detected memory errors to a known cyber-safe state.{SV-MA-3,SV-AV-7}{SI-17}
|
|
The [spacecraft] software subsystems shall initialize the spacecraft to a known safe state.{SV-MA-3,SV-AV-7}{SI-17}

|
|
The [spacecraft] software subsystems shall recover to a known cyber-safe state when an anomaly is detected.{SV-MA-3,SV-AV-7}{SI-17}
|
|
The [spacecraft] software subsystems shall safely transition between all predefined, known states.{SV-MA-3,SV-AV-7}{SI-17}
|
|
The [spacecraft] hardware root of trust must be an ECDSA NIST P-384 public key.{SV-IT-3}{SI-7(9)}
|
No requirement is imposed on uniqueness.
|
The [spacecraft] hardware root of trust must be loadable only once, post-purchase.{SV-IT-3}{SI-7(9)}
|
No requirement is imposed on preventing hardware readout. The public key belongs to the customer, not the manufacturer, so it must be loaded after purchase. Also, if it can be overwritten, there’s no reason to trust it.
|
The [spacecraft] shall implement trusted boot/RoT as a separate compute engine controlling the trusted computing platform cryptographic processor.{SV-IT-3}{SI-7(9)}
|
|
The [spacecraft] shall implement trusted boot/RoT computing module on radiation tolerant burn-in (non-programmable) equipment.{SV-IT-3}{SI-7(9)}
|
|
The [spacecraft] boot firmware must enter a recovery routine upon failing to verify signed data in the trust chain, and not execute or trust that signed data.{SV-IT-3}{SI-7(9),SI-7(10)}
|
No other requirements are imposed on the recovery routine besides not using the failed data. Unverifiable data isn’t trusted and shouldn’t be run.Â
|
The [spacecraft] secure boot mechanism shall be Commercial National Security Algorithm Suite (CNSA) compliant.{SV-IT-3}{SI-7(9),SI-7(10)}
|
No certification process is required (or exists). The CNSA is easy to meet, only restricts algorithm choice, and aids ease-of-use for government customers.
|
The [spacecraft] shall allocate enough boot ROM memory for secure boot firmware execution.{SV-IT-3}{SI-7(9),SI-7(10)}
|
|
The [spacecraft] shall allocate enough SRAM memory for secure boot firmware execution.{SV-IT-3}{SI-7(9),SI-7(10)}
|
|
The [spacecraft] shall support the algorithmic construct of Elliptic Curve Digital Signature Algorithm (ECDSA) NIST P-384 + SHA-38 or equivalent strength.{SV-IT-3}{SI-7(9),SI-7(10)}
|
Timing data may suggest cryptographic accelerators are unnecessary. This construct was chosen because (a) it’s in the CNSA suite and (b) it doesn’t require secret values to be stored
|
The [spacecraft] shall utilize strong fault management and redundancy to help mitigate threats against TT&C failure.{SV-AV-7}
