Therefore, an attacker must not be able to generate data or
data encryption keys through data source analogy.
Data Encryption Keys (DKs): keys that are generated and shared within a group and BS.
The credentials for decrypting the
data encryption key can then be passed to the local encryption device over an authenticated and encrypted session.
"POS vendors were all about to release this capability after spending lots of R&D and engineering money making it happen."<p>RKI technologies and services are designed to make the process of upgrading
data encryption keys on POS terminals quicker and cheaper than current manual methods because keys can be distributed to multiple POS systems directly over secure network connections and the Internet.
The master keys and
data encryption keys should be secured, and their integrity checked.
