Key Establishment

The process by which cryptographic keys are securely distributed among cryptographic modules using manual transport methods (e.g., key loaders), automated methods (e.g., key transport and/or key agreement protocols), or a combination of automated and manual methods (consists of key transport plus key agreement).

1. A protocol that reveals a secret key to its legitimate participants for cryptographic use. [After X9.42] 2. The procedure to share a common secret key among different parties by either key agreement or key transport. [After X9.42]
