CCA support for remote key loading solves one new problem, and one long-standing problem. This support allows the distribution of initial keys to ATMs and other remote devices securely using public-key techniques, in a flexible way that can support a wide variety of different cryptographic architectures. They also make it far easier and far more secure to send keys to non-CCA systems when those keys are encrypted with a triple-DES key-encrypting key. These changes make it easier for customers to develop more secure systems.
