Exploring The EMV Personalization Process

This article outlines the EMV personalization process, as well as reveals some industry best practices in relation to cryptographic key management.

EMV® Specifications provide the technical requirements for designing secure payment products that are compatible with multiple platforms

Today, almost 12 billion payment cards are based on the worldwide accepted EMV Chip Standards.

The EMV Chip Specifications are a set of standards developed by Europay, Mastercard, and Visa (EMV) to ensure the secure exchange of payment information between chip-enabled cards (or mobile devices) and terminals. These specifications are designed to reduce fraud and protect cardholder data. As such, they require that all cards be personalized with unique cryptographic keys that are used to authenticate transactions.

EMV chip specifications are a set of standards that provide a blueprint for chip technology to work consistently anywhere in the world. These specifications are designed to ensure that all EMV-compliant cards and terminals can securely communicate with each other, regardless of the country or region they are used in.

The specifications cover a variety of topics, including key management. Key management is an important part of EMV personalization. It involves the secure storage and distribution of cryptographic keys used to authenticate and authorize transactions. Keys must be securely stored in a tamper-proof environment, such as a hardware security module (HSM).

Card Personalization

The card personalization center is a highly secure area that is designed to protect the data and processes associated with EMV card personalization. This area is typically equipped with video monitoring and security guards to ensure that only authorized personnel have access. The security measures in place help to prevent unauthorized access to sensitive information, such as cardholder data, account numbers, and PINs.

The card vendor is responsible for pre-personalizing the card with an operating system, card application and data needed for the card to be personalized. This includes generating, storing, and distributing the keys used to secure the data on the card. The keys are used to encrypt and decrypt sensitive information stored on the card, such as account numbers, PINs and keys used in the transaction process.

The card vendor must generate a unique set of keys for each card that is personalized. These keys must be securely stored and managed in order to ensure that only authorized personnel have access to them.

Personalization Bureau

Personalization Bureau is a service provider that specializes in the personalization of EMV cards. The bureau offers a range of services, including key generation, encryption, and decryption. It also provides secure storage for keys and other sensitive data related to the personalization process. This includes loading the card with information such as account numbers, expiration dates, and other customer-specific data. It also involves formatting the data so that it can be read by the card reader.

EMV parameter settings must be defined by the card issuer, with more than a hundred parameters defining the rules of a transaction. EMV parameter settings are essential for the successful personalization of EMV cards. These parameters define the rules and regulations of a transaction, such as the type of card, the amount that can be spent, and the types of transactions that can be performed. The card issuer must define these parameters in order to ensure that all transactions are secure and compliant with industry standards.

Card profile definition is an essential part of the EMV personalization process. It involves defining the parameters that will be used to create a unique card profile for each cardholder. This includes setting up the card’s security features, such as PIN and encryption keys, as well as other parameters like account limits and transaction types.

Personalization Modules

A Hardware Security Module (HSM), is an essential component of the smart card personalization process. It provides secure storage and management of cryptographic keys used for authentication, encryption, and digital signing. This ensures that neither keys nor confidential data are in clear outside the HSM, providing a high level of protection against unauthorized access.

EMV personalization requires a secure key management system, this includes the ability to generate, store, and manage cryptographic keys in a secure environment.

Data Preparation Process

Creating an EMV data file requires data conversion of the issuer's card personalization file as part of a secure data preparation process that secures cardholder information. The first step of this process is to build an EMV personalization file out of the issuer's card personalization data. This file must include the relevant details to personalize an EMV card, such as the name and address of the cardholder, as well as their account information.

The next step is to use a secure key management system connected to a HSM that will be used to store and manage the cryptographic keys used for authentication, encryption, and digital signing. This system should include the ability to generate, store, and manage cryptographic keys in a secure environment. Finally, the data preparation process should also include the generation of an EMV personalization file that contains all of the necessary information (data, keys and certificates) needed to create an EMV card. This file should be securely stored and managed in order to protect against fraud and other malicious activities.

Data preparation and key management

Key management for EMV personalization involves the generation, distribution, storage, and secure use of cryptographic keys used to protect data stored on and used by EMV cards in the transaction process. The keys are used to encrypt and decrypt sensitive information such as cardholder data, account numbers, and other personal information.

The generation of keys is an important part of EMV personalization. Keys are used to secure the data stored on a chip card, as well as for authentication and authorization purposes. The generation of the keys is typically done by a secure key generator within a HSM that is designed to generate random numbers or strings.

Cryptomathic's CardInk is a comprehensive EMV data preparation and key management solution for secure generation, handling and transportation of cryptographic keys and certificates. It provides an efficient way to manage the lifecycle of EMV personalization keys, from initial key generation to secure storage and transport.

Conclusion

Key management is an essential part of the EMV personalization process. It involves generating, storing, and managing cryptographic keys in a secure environment. The Personalization Bureau provides a secure and efficient way to manage the key management process for EMV card personalization. This includes setting up the card’s operating system, loading the data needed for the card to operate, and securely transferring the personalization file to the card personalization center.

In conclusion, good key management is essential for an EMV personalization project to be successful. With the right protocols in place and a proper understanding of the technology, you can ensure a secure and seamless execution.
