HOW DOES MIFARE DESFIRE EV3 WORK IN AN ACCESS CONTROL READER?
MIFARE DESFire EV3 works in an access control reader by utilizing advanced security features and fast data transfer mechanisms to ensure secure and efficient authentication and access management.
Card Detection: When a user presents a MIFARE DESFire EV3 card to an access control reader, the reader detects the card using Near Field Communication (NFC) technology.
Mutual Authentication: The card and the reader authenticate each other using cryptographic protocols, such as AES-128. This process ensures that both parties are legitimate and authorized to communicate.
INITIALIZATION AND MUTUAL AUTHENTICATION
Encrypted Communication: Once authenticated, the card and reader establish an encrypted communication channel. This encryption protects the data exchanged from being intercepted or tampered with.
Transaction MAC: Each transaction between the card and the reader is secured with a Message Authentication Code (MAC), ensuring data integrity and authenticity.
SECURE DATA EXCHANGE
Access Request: The reader requests access credentials from the card. These credentials can include user ID, access levels, and other relevant data.
Data Retrieval and Decryption: The card retrieves the requested data from its secure storage and sends it to the reader. The reader decrypts and verifies the data.
ACCESS CREDENTIAL VERIFICATION
Access Rights Check: The reader checks the credentials against a predefined access control list or database to determine if the user has the necessary permissions to access the requested area or resource.
Entry Granted/Denied: Based on the verification, the reader either grants or denies access and sends a signal to unlock the door or gate.
ENTRY DECISION
Transaction Logging: The access control system logs the transaction details, including the user ID, time of access, and access point. This information can be for audit trails and monitoring.
Real-Time Monitoring: The system can provide real-time monitoring and alerts for any suspicious or unauthorized access attempts.
LOGGING AND MONITORING
KEY FEATURES IN ACTION
Proximity Check: Ensures the card is physically close to the reader, enhancing security by preventing relay attacks.
Transaction Timer: This feature limits the time window for completing transactions, adding an extra layer of security against certain types of attacks.
By leveraging these mechanisms, MIFARE DESFire EV3 provides a secure, efficient, and reliable access control solution. It ensures that only authorized individuals gain access to protected areas while maintaining high data security and integrity levels.
