Defines the interface and method used to initialize remotely a terminal cryptographic unit (TCU) using an asymmetric cipher algorithm.

This Standard defines the interface and method to initialize remotely a terminal cryptographic unit (TCU). In the context of this Standard the term initialization refers only to the initial set-up of a cryptographic keying relationship between the TCU and the acquirer.
