Flipper Zero and the security risks of the UID procedure in the Access control

In the world of access control, the Flipper Zero is a versatile device suitable for system developers and security experts is equally of interest. Designed as a multifunctional device for Working with frequencies and signal protocols, the Flipper Zero enables one Variety of operations: reading RFID cards, emulating data and signals send and receive. While the pinball zero for legitimate When used for security applications and testing purposes, it also highlights vulnerabilities particularly in systems based on the outdated UID method (Unique Identifier) based. But why is the UID process discontinued today? risk, and which alternatives offer safe solutions? Go to the following We will address these questions and consider the advantages of modern encrypted systems Technologies like MIFARE DESFire.

What makes the UID procedure insecure?

The UID, or “Unique Identifier”, is an immutable code that every RFID card or any contactless chip containing a specific card clearly identified. In many older access systems, this UID is called Only security mechanism used - if the code is with a If the card reader is compared, the bearer of the card gains access.

The crucial disadvantage of this method is thatUID codes in the Usually transmitted unencrypted. Anyone with access to one If you have a reading/writing device like the Flipper Zero, you can easily read the UID, save and emulate later to fool the system and gain access provide.

Tools like Flipper Zero can often generate UID codes in seconds copy and emulate since the device is designed to handle contactless data to read and interpret. This allows attackers to steal the UID of a to “clone” a legitimate card and thereby gain access – without it having to crack encrypted or authenticated information. For The UID procedure therefore discontinues areas that are safety-critical represents a significant risk.

MIFARE DESFire: The secure alternative for access control systems

Compared to UID-based systems, MIFARE DESFire offers one significantly better protection against unauthorized access. DESFire cards use AES encryption (Advanced Encryption Standard) and also offer a more flexible Architecture that allows multiple applications to run securely at the same time to execute a card. This multi-layer protection ensures that only authorized card readers can communicate with the card. That's how they are Cards not only through their UID, but through comprehensive authentication and encryption protocols protected.

DESFire's AES encryption ensures that the transmitted Data cannot be easily intercepted and decrypted, resulting in cloning and makes emulation of the card significantly more difficult. DESFire cards are special suitable for applications with high security requirements, such as Access systems for companies, public transport systems and environments, in where personal and business data must be kept secure. With DESFire cards can secure multiple access points within a system controlled and managed, making the entire system safer and more flexible might.

The importance of encryption in access systems

The use of encrypted technologies should, whenever possible, The priority is to protect access data and the integrity of systems ensure. In modern access control systems, encrypted access is prevented Communicateeffectively that sensitive data through unauthorized devices be tapped. This ensures that data transfer between Card and reader remain secure and attackers have no opportunity to access sensitive ones to access information and use it for illegitimate access.

Encryption, as used in MIFARE DESFire, also offers To increase security there is also the option to use cards for several people Use applications at the same time without changing the different applications compromise each other. This allows for greater versatility a single card can be used for different purposes, be it for access to offices, public transport or loyalty programs. The use of encrypted systems not only improves the security situation improved, but also ensures the future security of the access systems.
