1. General description
The NXP MIFARE SAM TM AV2 hardware solution is the ideal add-on for reader devices
offering additional security services. Supporting TDEA, AES and RSA capabilities, it offers
secure storage and secure communication in a variety of infrastructures.
Unlike other products in the field, MIFARE SAM AV2 has proven interoperability with all of
NXP's broad card portfolio, (MIFARE Ultralight, MIFARE Ultralight C, MIFARE 1K,
MIFARE 4K, MIFARE Plus, MIFARE DESFire, MIFARE DESFire EV1 and SmartMX
solutions), making it the most versatile and secure SAM solution on the market today.
Secured communication
When used in combination with a reader IC supporting innovative "X" features, MIFARE
SAM AV2 provides a significant boost in performance to the reader along with faster
communication between reader and module. The "X" feature is a new way to use the SAM
in a system, with SAM connected to the microcontroller and the reader IC simultaneously.
The connection between the SAM and the reader is performed using security protocols
based on either symmetric cryptography (TDEA and AES) or PKI RSA asymmetric
cryptography. The protocols comply with the state-of-art standards and thereby ensure
data confidentiality and integrity.
