Remember, in the realm of financial transactions, security is non-negotiable.

In today’s ever-evolving digital landscape, the protection of sensitive data stands as a top priority for organizations across various industries. Safeguarding critical information, such as Primary Account Numbers (PANs), is of utmost importance to ensure the confidentiality and integrity of customer data. One essential aspect of data security is the implementation of cleartext PAN removal, a defense-in-depth control mechanism designed to fortify data protection against unauthorized access. In this comprehensive article, we will delve into the significance of cleartext PAN removal and explore the implementation of secondary independent control systems to prevent breaches. Additionally, we will examine the utilization of keyed cryptographic hashing algorithms, incorporating randomly generated secret keys, as a robust measure to resist brute force attacks and ensure secret authentication integrity.

1. Understanding Cleartext PAN Removal:

In the realm of data security, the term “cleartext PAN” refers to the storage of Primary Account Numbers in an unencrypted and easily readable format. Storing PANs in cleartext poses a significant risk, as it leaves the data vulnerable to unauthorized access. To mitigate this risk, organizations employ the practice of cleartext PAN removal, which involves encrypting or hashing the PAN before storage.

When a PAN is encrypted, it is transformed into an unreadable form using an encryption algorithm and a corresponding encryption key. This ensures that even if an unauthorized individual gains access to the stored data, they would not be able to decipher the PAN without the encryption key. Encryption provides a high level of security but comes with the need to manage encryption keys securely to prevent unauthorized access.

Alternatively, organizations can employ cryptographic hashing algorithms to convert PANs into fixed-length hash values or digests. Hashing algorithms, such as SHA-256 (Secure Hash Algorithm 256-bit), apply a one-way process to the PAN, generating a unique hash value. This hash value is mathematically derived from the PAN but cannot be reversed to retrieve the original PAN. Therefore, even if an attacker gains access to the hashed PANs, they would not be able to retrieve the original PAN without engaging in a computationally expensive and time-consuming process known as brute force attack.

1. Secondary Independent Control Systems:

While cleartext PAN removal significantly enhances data security, organizations must implement secondary independent control systems to protect against potential breaches. These control systems act as an additional layer of defences, safeguarding the confidentiality of stored PANs even if the primary access control system is compromised.

Cryptographic Key Management:

One crucial aspect of secondary independent control systems is cryptographic key management. Cryptographic keys play a vital role in encryption, decryption, and hashing processes. By effectively managing these keys, organizations can ensure that only authorized individuals have access to the keys required to decrypt sensitive data or validate the integrity of hashed PANs.

Cryptographic key management involves various practices, including:

1. a) Access Controls:Strict access controls should be enforced to limit access to cryptographic keys. Only authorized personnel should have the necessary permissions to retrieve, use, or modify the keys.
2. b) Separation of Duties:Implementing separation of duties ensures that no single individual possesses complete control over the entire key management process. Dividing responsibilities among multiple individuals reduces the risk of unauthorized key access or misuse.
3. c) Key Rotation:Regular key rotation is essential to mitigate the impact of a compromised key. By frequently changing cryptographic keys, organizations can minimize the window of opportunity for attackers to exploit a stolen or compromised key.

Cryptography and Decryption Key Governance:

In addition to cryptographic key management, governance over cryptography and decryption keys is crucial for establishing a robust secondary independent control system. This governance framework outlines policies, procedures, and controls for the secure generation, distribution, usage, and destruction of keys.

The governance framework for cryptography and decryption keys should address the following:

1. a) Key Generation:Keys should be generated using strong random number generators to ensure their unpredictability and resistance to cryptographic attacks.
2. b) Key Distribution:Secure distribution mechanisms, such as secure channels or hardware security modules (HSMs), should be employed to transmit keys to authorized parties.
3. c) Key Usage:Proper controls should be in place to monitor and track the usage of keys. This includes logging key access, usage, and revocation activities.
4. d) Key Destruction:When keys are no longer needed or compromised, they should be securely destroyed to prevent unauthorized access to sensitive data.To Read Part 2,Click here

III. Keyed Cryptographic Hashing Algorithms :

To augment the security of hashed PANs, organizations can employ keyed cryptographic hashing algorithms. These algorithms incorporate a randomly generated secret key into the hashing process, significantly enhancing data protection against brute force attacks and ensuring secret authentication integrity.

HMAC (Hash-based Message Authentication Code):

HMAC is a widely used keyed cryptographic hashing algorithm that combines cryptographic hash functions with a secret key. It provides a robust mechanism to verify the integrity and authenticity of data. HMAC employs a specific hash function, such as SHA-256, along with a secret key, to generate a unique hash value for each PAN.

The process of computing an HMAC involves the following steps:

1. a) Message Padding:The PAN is padded to ensure a consistent length, as required by the hash function.
2. b) Key Padding:The secret key is also padded to match the block size of the underlying hash function.
3. c) Inner Hash:The padded secret key is XORed with a predefined inner padding value, and the result is concatenated with the padded PAN. The concatenated data is then hashed using the chosen hash function.
4. d) Outer Hash:The hashed result from the inner hash step is concatenated with the padded secret key XORed with a predefined outer padding value. The combined data is hashed again using the chosen hash function.

The final output of the HMAC process is the unique hash value that represents the PAN’s integrity and authenticity. Verifying the integrity of a PAN involves re-computing the HMAC using the stored secret key and comparing the generated hash value with the stored hash value.

CMAC (Cipher-based Message Authentication Code):

CMAC is another keyed cryptographic hashing algorithm that provides enhanced security by preventing known-plaintext attacks. It is based on a block cipher, such as AES (Advanced Encryption Standard), and employs a secret key to generate a message authentication code.

The process of computing a CMAC involves the following steps:

1. a) Initialization:The CMAC algorithm initializes the block cipher with the secret key, setting up the initial state.
2. b) Message Processing:The PAN is processed block by block using the block cipher’s encryption function, incorporating the secret key and the previous block’s result.
3. c) Padding:If the PAN length is not a multiple of the block size, padding is applied to ensure a complete block.
4. d) Finalization:The final block is processed using the block cipher, producing the CMAC value.

Similar to HMAC, verifying the integrity of a PAN using CMAC involves re-computing the CMAC value and comparing it to the stored value.

GMAC (Galois Message Authentication Code):

GMAC is a keyed cryptographic hashing algorithm primarily used in authenticated encryption schemes, providing both confidentiality and integrity assurances. It employs a secret key, a nonce (a unique number used once), and a message to generate a MAC (Message Authentication Code) that guarantees data integrity and authenticity.

The process of computing a GMAC involves the following steps:

1. a) Initialization:The GMAC algorithm initializes the Galois field, incorporating the secret key.
2. b) Message Processing:The PAN, along with the nonce, is processed block by block using the Galois field multiplication and addition operations.
3. c) Finalization:The final GMAC value is generated by processing the last block and incorporating the final Galois field calculations.

GMAC enables the recipient of the PAN to validate the integrity and authenticity of the data by re-computing the GMAC value using the received PAN, the same secret key, and the nonce.

Conclusion:

In an era where data breaches and unauthorized access pose significant threats to organizations and their customers, implementing robust data security measures is crucial. Cleartext PAN removal serves as a critical defense-in-depth control, ensuring that stored PANs remain protected even in the event of an unauthorized breach. By encrypting or hashing PANs, organizations mitigate the risk of exposing sensitive data to unauthorized individuals.

Furthermore, secondary independent control systems, including cryptographic key management and governance frameworks, bolster the overall security posture. These systems ensure that access to cryptographic and decryption keys is tightly controlled, reducing the likelihood of unauthorized access and misuse.

Keyed cryptographic hashing algorithms, such as HMAC, CMAC, and GMAC, provide an additional layer of security by incorporating randomly generated secret keys. These algorithms resist brute force attacks and enhance the integrity and authenticity of hashed PANs.

By adopting these practices, organizations demonstrate a commitment to data security, safeguarding sensitive information and maintaining the trust of their customers and stakeholders.

A successful PCI DSS gap assessment demonstrates an organization’s commitment to security and compliance. It instills confidence in customers, partners, and stakeholders, as they can trust that their payment card data is handled responsibly. Compliance with PCI DSS not only meets the requirements set by payment card brands but also aligns with broader data protection and privacy regulations. This alignment can simplify compliance efforts for organizations operating in multiple regulatory environments.

PCI SSC maintains various PCI standards, supporting programs, and related documentation. PCI Security Standards are developed specifically to protect payment account data throughout the payment lifecycle.

1. PCI DSS (Payment Card Industry Data Security Standard) : PCI DSS covers security of the environments that store, process, or transmit account data. The scope of PCI DSS covers environments receiving account data from payment applications and other sources—acquirers. Generally applicable for merchants, Service Providers, any payment solution providers.
2. PCI Secure Software Standard ( 3S) : The Secure Software Standard defines a set of security requirements to help ensure payment software adequately protects the integrity and confidentiality of payment transactions and data. The Secure Software Standard includes a set of “core” requirements that apply to all types of payment software submitted for validation under the PCI Software Security Framework, regardless of the software’s functionality or underlying technology. Generally applicable for Payment Software vendors who would like to sell their Payment Software to their customers as a off the shelf-product.
3. PCI Secure Software Lifecycle: The PCI Secure Software Lifecycle (Secure SLC) Requirements provides a baseline and guidance to help payment software design, develop, and maintain secure payment software throughout the software lifecycle. Generally applicable for Software Development vendors who would like to develop payment software on behalf of their customers.
4. PCI 3DS ( Three Domain Secure): This standard helps the entities who perform the 3DS Server (3DSS), 3DS Directory Server (DS), 3DS Access Control Server (ACS) Functions.   3DS is a messaging protocol that enables end users to do a multi factor authentication themselves with their card issuer when making any online purchases / E-commerce Transactions. Generally applicable for Acquirers (Merchant Banks) and Issuers (Cardholders Bank).
5. PA DSS (Payment Application Data Security Standard): PCI PA-DSS covers secure payment applications to support PCI DSS compliance. The scope of PA-DSS addresses when a payment application receives account data from cardholder-interface devices such as point-of-sale terminals or other devices and begins the payment transaction. However PA-DSS is replaced by PCI Software Security Framework. Generally applicable for Payment Application vendors who would like to sell their application as a off the shelf product.
6. PCI PTS – POI (Payment Card Industry PIN Transaction Security Point of Interaction): The PCI PTS – POI standard covers device tamper detection, cryptographic processes, and other mechanisms used to protect the PIN and other sensitive data, such as cryptographic keys. Generally applicable for Device Manufacturers.
7. PCI PTS – PIN ( Payment Card Industry PIN Transaction Security – Personal Identification Number: The PCI PTS – PIN standard covers secure management, processing and transmission of personal identification number (PIN) data during online and offline payment card transaction processing. Generally applicable for Device Manufacturers.
8. PCI PTS – HSM ( Payment Card Industry PIN Transaction Security – Hardware Security Module): The PCI PTS – HSM standard covers the design of hardware security modules and for securely protecting those devices until they are deployed. Generally applicable for HSM Device Manufacturers.
9. PCI P2PE (Payment Card Industry Point-to-Point Encryption) : PCI P2PE (Point-to-Point Encryption) covers secure encryption, decryption, and key management for point-to-point encryption solutions. Requirements for a P2PE solution will vary depending on the deployment environment and the technologies used for a specific implementation. Generally applicable for the service providers who are providing end to end encryption solutions for their merchants.
10. PCI Contactless Payments on COTS ( CPoC): The PCI Contactless Payments on COTS (CPoC) Solutions enable contactless payment acceptance on a merchant’s consumer device using an embedded (near-field communications) NFC interface. This listing is a resource for merchants and acquirers to use in selecting a Contactless Payments on COTS (CPoC) Solutions. Generally applicable for PIN on Mobile Solution providers.
11. PCI Software-Based PIN Entry on COTS (SPoC) : Also famous as PIN on mobile device. This Standard provides requirements for developing secure solutions that enable EMV contact and contactless transactions with PIN entry on the mobile devices of consumers using a secure PIN entry application in combination with a Secure Card Reader for PIN (SCRP). Generally applicable for PIN on Mobile Solution providers.
