How does the PACE Protocol work?

< 1 min read

  1. Purpose: PACE enhances the security of the data communication between the card and the reader. It’s used to prevent unauthorized access and eavesdropping.
  2. Functionality: When an NFC card is tapped or brought close to a reader, PACE establishes a secure, encrypted communication channel. This process involves mutual authentication, ensuring both the card and the reader are legitimate.
  3. User Authentication: Typically, PACE uses a PIN or a Card Access Number (CAN) for initiating the process. The CAN is often a 6-digit number printed on the card.
  4. Key Agreement: During the PACE protocol, both the card and the reader agree upon a temporary encryption key. This key is used to encrypt the communication, making it secure from external threats.
  5. Data Protection: By encrypting the data transmission, PACE protects personal information like biometric data and other sensitive details stored on the card.
  6. Widespread Use: PACE is commonly used in e-Passports and other government-issued NFC identity documents across various countries.
