The security landscape for critical national infrastructure is ever-evolving, with threats becoming more sophisticated and operations becoming more complex. That is why it is crucial that every element of your security system, including physical and cyber, remains highly secure. The introduction of DESfire technology family in the 2000’s made a significant leap forward in securing sensitive environments, providing organizations with cutting-edge security smart cards that can adapt to modern-day challenges.

However, unless DESFire is managed and deployed in the right way, there still remains significant risk that your security system can be compromised. But what exactly is DESfire, and how can it revolutionize your approach to security management?

 

What is DESFire?

DESFire is a type of smart card technology developed by NXP, primarily used in contactless cards for secure applications such as access control, transportation systems, cashless payments, and identity management. The term “DESFire” comes from the encryption algorithms it uses, with “DES” standing for Data Encryption Standard, and “Fire” referring to the card’s Fast, Innovative, Reliable, and Enhanced capabilities.

It is based on global open standards adopted which means it is ideally suited to developers and system manufacturers. In today’s security market, DESFire has become the gold standard for smart technology.

Key Features About DESfire

DESFire technology offers a robust, secure, and versatile solution for modern access management. With advanced encryption, multi-application support, high processing speed, and compatibility with existing systems, DESFire cards deliver the flexibility and performance needed to streamline operations while ensuring top-tier security across various applications.

Security

DESFire cards are highly secure, supporting encryption standards such as 3DES (Triple DES) and AES (Advanced Encryption Standard). They offer mutual authentication, encrypted communication, and secure key storage.

 

Compatibility

DESFire cards are part of the MIFARE product family, developed by NXP Semiconductors. They are backward-compatible with other MIFARE systems, making them versatile for integration in existing infrastructure.

Flexibility

DESFire cards are highly flexible and can store multiple applications. This makes them suitable for multi-purpose uses, such as using a single card for public transport, building access, and payment systems.

High Performance

The cards are known for their fast processing speed and reliability, making them ideal for systems where quick read/write operations are essential, like mass transit systems.

 

Memory

DESFire cards come with different memory sizes, allowing them to store various data, such as personal details, access credentials, or e-wallet information, depending on the application.

The Importance of Correct Deployment and Management

Deploying DESFire for security with your access control system requires careful planning. Organizations must consider the token architecture, encryption standards, and key management strategies, including key diversification and key rolling. By implementing the right protocols from the start, such as diversified keys to minimize the risk of key compromise, you can maintain the highest security standards, avoiding vulnerabilities during key issuance, replacement, or removal processes.
