Adds new technology to the financial community's suite of security mechanisms. The new technology will provide a more flexible and granular means for controlling the production and usage of keys. The Key Management scheme proposed in this new work item provides flexible and secure methods for handling keys. The "Key Establishment" portion of key management allows designated groups of users to establish keys via a key derivation procedure, thus avoiding key distribution in the usual sense. The "Key Usage Control" portion of the key management allows users to control the usage of key, where the keys are either stored or transmitted within a cryptographic system.
