What does TPI stand for in COMSEC terminology?

• A. Two Person Integrity Policy
• B. Two Person Information
• C. Two Person Integrity
• D. Dual Operator Accountability

Answer: (C)

In COMSEC, Two Person Integrity is a dual-control approach that requires two authorized individuals to be involved in handling sensitive crypto material and performing critical operations. This setup provides checks and balances, helps prevent theft or tampering, and ensures accountability for key material management. That’s why the correct option is Two Person Integrity. The other phrases don’t match the established term: adding “Policy” changes the standard terminology, and the remaining options don’t reflect the dual-control concept used in crypto material handling. In practice, this means activities like loading keys or accessing secure crypto equipment are performed only when two trusted operators are present.
