TPI stands for which term?

• A. Two Person Integrity
• B. Three Person Integrity
• C. Trusted Personal Interface
• D. Two Phase Integrity

Answer: (A)

Two-Person Integrity is a security practice that requires two authorized individuals to access or manipulate cryptographic material or secure equipment. In the AN/PRC-160 and AN/PRC-163, this means crypto keys or other sensitive crypto material must be handled with the involvement of two people, preventing a single operator from loading keys or compromising the crypto without another person’s oversight. In practice, one person might operate the device while the other provides authorization or custody of the keys, and both must be present to complete any action involving secure material. The other terms don’t reflect standard DoD crypto security policy—three-person integrity isn’t the recognized rule for this context, a trusted personal interface isn’t the correct term, and two-phase integrity isn’t used here.
