HID DESFire EV3 cards leverage security features including AES128 encryption, secure channel-based file transfer, and proximity check to protect card data from attack. Furthermore, unlike many other DESFire solutions available on the market, Random UID has also been introduced to ensure the card will never openly share any information that could be associated with the user. Finally, EV3 credentials from HID offer layered security with the addition of a Secure Identity Object (SIO) data model for added key diversification, authentication signatures, and encryption.
