The Act authorizes NIST to work with other government agencies and private industry in evaluating proposed technology standards. Table 25.2 Orange Book Classifications D: Minimal Security C: Discretionary Protection C1: Discretionary Security Protection C2: Controlled Access Protection B: Mandatory Protection B1: Labeled Security Protection B2: Structured Protection B3: Security Domains A: Verified Protection A1: Verified Design NIST issues standards for cryptographic functions. U.S. government agencies are required to use them for sensitive but unclassified information. Often the private sector adopts these standards as well. NIST issued DES, DSS, SHS, and EES. All these algorithms were developed with some help from the NSA, ranging from analyzing DES to designing DSS, SHS, and the Skipjack algorithm in EES. Some people have criticized NIST for allowing the NSA to have too much control over these standards, since the NSA’s interests may not coincide with those of NIST. It is unclear how much actual influence NSA has on the design and development of the algorithms. Given NIST’s limited staff, budget, and resources, NSA’s involvement is probably considerable. NSA has significant resources to contribute, including a computer facility second-to-none.
