Improved remote key distribution

New methods have been added for securely transferring symmetric encryption keys to remote devices, such as Automated Teller Machines (ATMs), PIN-entry devices, and point of sale terminals.

These methods can also be used to transfer symmetric keys to another cryptographic system of any type, such as a different kind of Hardware Security Module (HSM) in an IBM® or non IBM computer server.

This change replaces expensive human operations with network transactions that can be processed quickly and inexpensively. This method makes significant interoperability improvements to related cryptographic key-management functions.

In Remote key loading, an ATM scenario illustrates the operation of the new methods. Other uses of this method are also possible.
