The NIST basic cryptographic primitives are those on which other cryptographic procedures depend.  These include pseudo-random generators and message digest algorithms.  There are also prerequisite primitives that do not themselves provide nor rely upon encryption/decryption techniques on which the basic cryptographic primitives will depend.

1. Prerequisites

Usage and testing of the basic NIST-specified primitives requires means for satisfying the following prerequisites:

• Encoding and decoding of binary data in hexadecimal and base64 encoding
• Procedures for producing, accessing, and verifying test materials in the formats employed in NIST verification procedures
• Existing implementations of algorithms for comparison and testing
• Pseudo-random generators for testing and confirmation as part of bootstrapping cryptographically-acceptable procedures

These elementary procedures are available from numerous sources.  Dependencies on them will be identified as part of specific development activities.  Useful generic resources may be catalogued separately.

2. Secure Hash Algorithms

2.1 Basic Characteristics

2.2 NIST Secure Hash Standards

2.3 NIST Secure Hash Certification Testing

2.4 NIST Secure Hash Implementation and Testing

2.5 Hash Algorithm Threats and Vulnerabilities

2.6 nfoWorks Secure Hash Development

3. Pseudo-Random Generators

{Author Note:

The definitive sources are NIST SP 800-90/A/B/C.

SP 800-131A Rev.1 is also relevant.

These provide parameters and nomenclature that we shall adopt. 

We need to consider the impact, for the use in a stream cipher, such as an SCE, that the DRBG is shared between the parties, although the seeds and reseeds are secrets.
