DESFire® EV2 (Data Encryption Standard Fire EV2) is a technology used in a variety of applications requiring high security, such as public transportation systems, identity cards, access control systems, and payment solutions. Here is a detailed overview of DESFire® EV2 technology:
Advanced security with DESFire® EV2 technology
- AES Encryption: Uses the Advanced Encryption Standard (AES), providing robust protection against interception and hacking attempts.
- Mutual Authentication: The card and the reader mutually authenticate each other before any data exchange, preventing unauthorized devices from accessing information.
- Cloning Protection: Designed to be completely resistant to cloning thanks to its advanced security mechanisms.
Flexibility and application management
- Multi-application support: Can host multiple distinct applications on a single card, each protected by its own encryption keys, allowing for use in various services (transportation, building access control, payments) while keeping data separate and secure.
- Ease of management: New applications can be added and old ones removed without compromising other applications, offering flexible and dynamic service management.
Performance and capacity
- Transaction speed: Optimized for fast transactions, crucial for high-throughput applications like public transportation.
- Large memory capacity: Available in various memory sizes (up to 8 KB), allowing for the storage of large amounts of data for diverse applications.
Compatibility and integration
- Interoperability: Compatible with existing infrastructures using MIFARE technologies, facilitating integration and upgrading of access control systems.
Practical applications
- Access control: Used in buildings, businesses, and secure facilities to manage and restrict access.
- Public transport: Used for transport cards offering fast and secure transactions.
- Identity and payment cards: Used for secure identity cards and contactless payment solutions.
DESFire® EV2 is an advanced contactless smart card technology that offers enhanced security, great flexibility, and fast performance. These features make it an ideal choice for applications requiring secure and fast data, while allowing for flexible management of multiple services on a single card. DESFire EV2 technology has become essential for sites where protection against cyber threats is a priority.
