In cryptographic standards, which description is correct for Type 1 and Type 4?

• A. Type 1: highest; Type 4: lowest
• B. Type 4: highest
• C. Type 2: highest; Type 1: lowest
• D. Type 1: lowest; Type 4: highest

Answer: (A)

In cryptographic standards, the Type designations reflect levels of government validation and assurance for crypto solutions. Type 1 is the highest level because these devices or algorithms are NSA-approved and used to protect classified national-security information, requiring rigorous evaluation and certification. Type 4 is the lowest level, representing non-certified, publicly available cryptography that is not approved to protect classified data. So describing Type 1 as the highest and Type 4 as the lowest correctly captures the intended hierarchy and usage.
