Defines a method for digital signature generation and verification for the protection of messages and data using the Digital Signature Algorithm (DSA). This standard is used in conjunction with the hash function, as defined in American National Standard for Public Key Cryptography - Part 2: The Secure Hash Algorithm (SHA-1), BSR X9.30.2. In addition, this standard provides the criteria for the generation of public and private keys that are required by the algorithm and the procedural controls required for the secure use of the algorithm. Specific sections include definitions and common abbreviations, application, the DSA, Generation of Primes for the DSA, Random Number Generation for the DSA.
