Card Reader and the BlackBerry device or computer. By default, the secure pairing PIN is 8 characters long and is case-sensitive. If your organization uses BlackBerry Smart Card Reader version 2.0 and later and BlackBerry® Device Software version 5.0 and later, you can change the length of the secure pairing PIN using the Minimum PIN Entry Mode IT[...]

4. The BlackBerry Smart Card Reader creates a list of all the algorithms that it supports and sends the supported algorithms list to the BlackBerry device or computer. 5. The BlackBerry device or computer searches the list for a match with one of its own supported algorithms. • If a match is not available, the BlackBerry device or computer sends [...]

The connection key establishment protoc ol uses the ECDH algorithm that th e initial key establishment protocol negotiates. The ECDH algorithm provides Perfect Forward Secrecy, which uses the key that protects data to prevent the protocol from deriving previous or subsequent encryp tion keys. Each run of the connection key establishment protocol us[...]

For more information about variables used in this process, see “ BlackBerry Smart Card Reader shared cryptosystem parameters ”. The connection key establishment protocol can stop at any point if an error occurs. For more information, see “ Connection key establishment protocol errors ”.
