Announcement
Draft NIST Special Publication (SP) 800-71, Recommendations for Key Establishment Using Symmetric Block Ciphers, addresses key establishment techniques that use symmetric key cryptography algorithms to protect symmetric keying material. The objective is to provide recommendations for reducing exposure to the unauthorized disclosure of the keying material and detecting its unauthorized modification, substitution, insertion or deletion. The Recommendation also addresses recovery in the event of detectable errors during the key-distribution process. Wrapping mechanisms are specified for encrypting keys, binding key control information to the keys and protecting the integrity of this information.
