Electronic funds transfer — Requirements for interfaces, Part 6.5.3: Key management — TCU initialization — Asymmetric
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 symmetric cryptographic keying relationship between the TCU and the acquirer(s).
