What condition makes the TKL become Two Person Integrity (TPI)?

• A. Top Secret cryptographic keys loaded into the TKL
• B. Four Black Keys loaded
• C. It becomes TPI in Tactical mode
• D. It becomes TPI when power is removed

Answer: (A)

Two Person Integrity is enforced whenever handling Top Secret cryptographic material. In the Tactical Key Loader, loading Top Secret keys means dual custody is required, so the device automatically switches to TPI to ensure two authorized personnel must be involved in loading, handling, or using those keys. This dual-control setup prevents a single operator from accessing highly sensitive material and provides accountability. Loading four Black Keys, operating in Tactical mode, or removing power do not by themselves invoke the dual-Custody requirement, so they do not trigger TPI.
