CCA Release 2.54 Revision History
1. Functions in support of EMV-compatible smart-cards.
Support of the PIN Change/Unblock function described in the VISA
Integrated Circuit Card Specification Manual, Section C.11
Support of the key-generation function used for secure messaging
described in the VISA Integrated Circuit Card Specification Manual, Section
B.4
Encryption of PINs and keys for inclusion in smart-card transactions with
EMV-compatible smart cards.
This support is provided through:
A new verb, PIN_Change/Unblock (CSNBPCU), to create a PIN block to
change the PIN accepted by a smart card
An extension to the Diversified_Key_Generate (CSNBDKG) verb enabling
session-key generation for secure messaging
A new verb, Secure_Messaging_for_Keys (CSNBSKY), to encrypt a key
under a session key
A new verb, Secure_Messaging_for_PINs (CSNBSPN), to encrypt a PIN
under a session key
The next item relating to ISO 9796-2 digital signature verification.
2. An extension to the PKA_Encrypt (CSNDPKE) verb enabling verification of
digital signatures with any hash formatting method (for example, ISO 9796-2)
through the public-key enciphering of data in the zero-pad format.

Release 2.41
This revised Release 2.41 manual, dated September, 2003, contains minor editorial
changes and these corrections:
Figure C-3 on page C-5 is changed to note that a SECMSG key is always
double length (“fff” bits changed to “FFF”).
Figure C-3 on page C-5 is changed to reflect that key-encrypting keys, bits
35-37, must be B'000'. The text in item 2 of section “Specifying a
Control-Vector-Base Value” on page C-7 which previously described these bits
has been removed. Testing for these control vector bits has not been
implemented.
The padding for a Current Key Serial Number must be four bytes of X'00'
rather than four space characters as previously stated in “Current Key Serial
Number” on page 8-11.
The revision bar, as shown at the left, marks the important changes.
