AS2805

AS2805 is the Australian standard for financial news. It is used almost exclusively in Australia for card-based financial transactions between banks, ATMs and EFTPOS devices. The financial messages described in this standard are closely related to ISO 8583, but are two years older (1985 vs. 1987).

The AS2805 functionality provided by CCLC supports terminal key set generation, PIN block translation, as well as MAC and OWF address generation.

Generate a set of terminal keys

Generates a set of terminal keys such as Terminal PIN Key (TPK), Terminal Authentication Key Receive (TAKr), Terminal Authentication Key (TAK) Send, Terminal Encryption Key Receive (TEKr), and Send Terminal Encryption Key (TEK) and returns each encrypted key under the Terminal Master Key (TMK) or KMA variant and the corresponding LMK pair. CCALC generates a Key Verification Value (KCV) for each output key.

The KEK flag specifies which key is used 1 = KEK1, 2 = KEK2, 3 = TEKr.

Key Encryption The receive key (KEKr) must always be provided in the form of hexadecimal digits (0-9 | A-F), and the acceptable key length is 32. The key is encrypted in the appropriate variant of the LMK 14-15 pair.

The KEK key scheme tells you which key scheme will be used to encrypt the keys within the KEKr.

The LMK key scheme tells you which key scheme will be used to encrypt the keys in the LMK.

The KCV type sets the length of the key check value (1 = KCV 6H)

translate pin lock

This function converts the Encryption PIN Block to Encryption PIN Key (KPE) to Zone Encryption PIN Key (ZPK). The KPE comes from the Terminal PIN Key (TPK) and two other values, the System Audit Trail Number (STAN) and the transaction amount.

The Zone PIN Key (ZPK) must always be given in the form of hexadecimal digits (0-9 | A-F), and the acceptable key length is 32. The key is encrypted in variant 0 of the LMK 06-07 pair.

The Terminal Key (TPK) PIN code must always be provided in the form of hexadecimal digits (0-9 | A-F), and the allowed key length is 32. The key is encrypted in variant 0 of the LMK pair 14-15 .

Received and responded PIN lock formats must be a valid PIN lock format code (for example, 01, 46).

The ReceivedPIN block is encrypted in KPE.

Account number with the last 12 digits of the PAN, except the amount of the check (12N).

The following diagram shows the translation of a PIN block from KPE to ZPK and the conversion between PIN block formats.

OWF

The One Way Function (OWF) is the foundation of AS2805 and is used in most of the above key generation functions. The CCLC implementation complies with the AS2805.5.4 standard described below.

Let K be the DES key and let D be a data block of arbitrary size, n bits.
If n is not a multiple of 64, add a single binary '1' followed by as many binary zeros as necessary to make the data a multiple of 64 bits (possibly none).
Let D* denote the supplemented data.

The key (YES) must always be given as hexadecimal digits (0-9 | A-F) and the allowed key length is 32. The key is plain (unencrypted).

DUKPT

DUKPT (ISO 9797)

DUKPT panels consist of tabs that comply with the ISO-9797 standard: IPEK Source, PEK Source, PIN Encryption, and MAC Encryption. The method described in ISO-9797 uses an Initial PIN Encryption Key (PEK) and a PIN Encryption Key (PEK) to encrypt a PIN block encryption with a unique key per transaction, and also uses a variant of this key to generate a MAC on the provided transaction data.

PEK derivation

The derived functions IPEK and PEK are the first options available. They require a Base Derived Key (BDK) and Key Serial Number (KSN) or IPEK and KSN for PEK output as input parameters. The BKD and IPEK keys are expected to be entered in hexadecimal format and twice the length. The KSN consists of hexadecimal digits (0-9 | A-F) and the length of the entry must be 20 characters.

DUKPT PIN

The PIN DUKPT screen allows you to encrypt/decrypt a PIN block using a PEK. The input values are similar to the screens above, just note that the entered PEK will be XORed with the value 000000000000000FF 00000000000000FF (see ANSI X9.24-2004 Appendix A, A.5, page 42) as part of the processing. Therefore, it is not necessary to perform this operation beforehand (this would be exactly the negation of the previous change).

DUKPT MAC

The DUKPT MAC screen uses the BDK, KSN, and Data fields and outputs an ANSI X9.24-2004 MAC with padding of 1. All input fields are expected to be in hexadecimal format with the correct length (single/double DEA/triple DEA ). Please note that the length of the data field is limited to 8120 characters. The 3DES switch is used to indicate whether the last cryptographic operation applied to the hash value should be single or triple DES (default).

The entered PEK value is XORed with the value 000000000000FF00 00000000000FF00 (see ANSI X9.24-2004 Appendix A, A.5, page 42) as part of the processing.

DUKPT data

The last screen gives you the option to encrypt or decrypt your data using your current PEK. The entered PEK value is XORed with the data key variant 0000000000FF0000 0000000000FF0000. (Unchecking the Data Variant check box will return the value to 00000000000000FF 000000000000000FF.)
In order to achieve a high degree of isolation between the data encryption key and the PIN key, the IMF must process the data encryption key before use. The OWF defined here is that the value of the derived variant is encrypted using itself as the key.

DUKPT (AES)

The DUKPT panels consist of ANSI X9.24-3-2017 compliant tabs: IPEK Source, PEK Source, PIN Encryption, and MAC Encryption.

The standard describes the AES DUKPT algorithm that is used to extract keys from the initial DUKPT terminal key based on the transaction number.
Derived keys can be used for a variety of functions, such as encrypting PINs, data, or other keys, obtaining other keys, authenticating messages, and so on.
AES DUKPT supports the derivation of double- and triple-length AES-128, AES-192, AES-256, and TDEA keys from AES-128, AES-192, and AES-256 seed keys.

PEK derivation

The derived functions IPEK and PEK are the first options available. They require a Base Derived Key (BDK) and Key Serial Number (KSN) or IPEK and KSN for PEK output as input parameters. BKD and IPEK are expected to be entered in hexadecimal format. KSN has hexadecimal digits (0-9 | A-F) and the length of the entry must be between 16 and 24 characters.

ANSI X9.9 (MAC wholesale)

The ANSI X9.9 MAC screen is used to generate the message authentication code (MAC) as described in the ANSI X9.9 specification. This is a fairly old retail banking technique that still proves to be very fast and protects data integrity from point of sale to acquirer.

The display receives a unique length DEA cryptographic key and hexadecimal data and MAC outputs.

ANSI X9.19 (MAC retail)

ANSI X9.19 is another banking standard created by the ANSI X9 working group and published by the American Bankers Association. X9.19 is basically an update to ANSI X9.9, with some minor changes to handle the transition from wholesale banking in X9.9 to retail banking in X9.19.

The ANSI X9.19 MAC generator uses ANSI 9.19 (ISO/IEC 9797-1 Algorithm 3) with padding method 1 algorithm to generate the message authentication code in the payment industry. It takes two single-length DEA keys and applies the procedure described in ANSI X9.19 MAC to the hexadecimal data provided in the Data field.

TDES CBC-MAC

TDES CBC-MAC: A Cipher Block Chaining Message Authentication Code (CBC-MAC) is a technique for creating a message authentication code from a block cipher. The message is encrypted with some block cipher algorithm in CBC mode to form a chain of blocks so that each block is based on the corresponding cipher of the previous block. This interdependence ensures that changing any bit of the plaintext will change the final encrypted block in a way that cannot be predicted or countered without knowing the block's cipher key.

HMAC

In cryptography, HMAC (sometimes augmented as hash message authentication code or hash-based message authentication code) is a specific type of message authentication code (MAC) that includes a cryptographic hash function and a cryptographic key. Like any MAC, it can be used to simultaneously verify the integrity of the data and the authenticity of the message.
HMAC can be used with any iterative cryptographic hash function, eg MD5, SHA-1, in combination with a shared secret key.

The cryptographic strength of an HMAC depends on the properties of the underlying hash function.

CMAC

CMAC (Cryptographic-Based Message Authentication Code) is a message authentication code algorithm based on a block cipher. It can be used to ensure the authenticity and therefore the integrity of binary data. This mode of operation corrects the security flaws of CBC-MAC (CBC-MAC is only secure for fixed-length messages).

PIN Swipe (IBM 3624 method)

Route

To allow the customer to choose their own PIN, the IBM 3624 PIN generation algorithm uses PIN offset to match the customer's selected PIN to the generated PIN.

The PIN offset generation algorithm requires two parameters in addition to those used in the 3624 PIN generation algorithm. These are the customer-selected PIN and the 4-bit PIN check length. The length of the PIN chosen by the customer is the same as the length of the assigned PIN.

The compensation data value is the result of subtracting (modulo 10) the leftmost n digits of the intermediate PIN from the PIN selected by the customer.

PvP PIN Calculator

The VISA method generates a PIN code verification value (PVV). Like the compensation amount, it can be stored in card tracking data or in the card issuer's database. This is called the baseline PVP.

The VISA method takes the eleven rightmost digits of the PAN, excluding the checksum value, the PIN verification key index (PVKI, selectable from one to six), and the PIN value needed to create a 64-bit number, PVKI selects verification key (PVK , 128-bit) to encrypt this number. Based on this encrypted value, the PVV is found.

To verify the PIN, the issuing bank calculates the PVV based on the entered PIN and PAN and compares this value to a reference PVV. If the reference PVV and the calculated PVV match, you have entered the correct PIN.

Unlike the IBM method, the VISA method does not generate a PIN. The PVV value is used to confirm the PIN entered in the terminal, it was also used to generate the PVV reference. The PIN used to generate the PVV can be randomly generated or selected by the user, or even obtained through an IBM method.

This algorithm generates a 4-digit PVV. The entries are PIN Bypass Key, PAN, PIN, and PIN Verification Key Indicator (PVKI). The assigned PVV length parameter is encoded = 4.
