CryptoCompanion provides plug-and-play host-side **RFID cryptographic security** for embedded systems. This plug-and-play convenience means that designers do not have to design or test the cryptographic algorithms. The *RFID* companion chip implements the necessary algorithms and the entire protocol completely in hardware. It’s fully tested and guaranteed to work properly with all CryptoMemory/CryptoRF chips.

To validate the **RFID authenticity** of a consumable or replaceable item (a.k.a. client) connected to a system (a.k.a. host), there must be some secret information stored in both the client and the host. The CryptoMemory and CryptoRF devices provide a secure location to store this secret data in the client and the CryptoCompanion chip provides a way to securely store this secret in the host.

Atmel’s CryptoRF is the world’s first 13.56 MHz **RFID devices** with a 64-bit embedded cryptographic engine, dual authentication capability, and up to 64 Kbits of memory, each with up to 16 individually configurable sectors.

CryptoRF product labels, tags, and cards are virtually impossible to copy and offers hardware security, which is superior to any software solution.
