Description
Cryptography is only as strong as the encryption modules/algorithms employed to encrypt the data. Use of weak or un-tested encryption algorithms undermines the purposes of utilizing encryption to protect data. NSA has developed Type 1 algorithms for protecting classified information. The Committee on National Security Systems (CNSS) National Information Assurance Glossary (CNSS Instruction No. 4009) defines Type 1 products as: Cryptographic equipment, assembly or component classified or certified by NSA for encrypting and decrypting classified and sensitive national security information when appropriately keyed. Developed using established NSA business processes and containing NSA approved algorithms are used to protect systems requiring the most stringent protection mechanisms. This is outside the scope of DNS. DNS will not provide the Type 1, NSA devices will provide that functionality.
