Atmel’s CryptoRF™ is a new secure RF family of devices with memory densities from
1 Kbit (AT88SC0104CRF) to 64 Kbits (AT88SC6416CRF) for contactless smart card
applications. This new family of secure RF circuits makes available to the industry a low
cost, high security chip solution that fills the void between simple RFID memories and
RF microcontrollers.
Security
This device contains a random number generator and proprietary algorithm that generates new
keys for each authentication and encryption activation. Read and Write access requirements for
each user zone are programmed by the customer during card personalization. The device’s
secret keys for mutual authentication and encryption are defined using a customer selected
algorithm. Only a computer knowing both the CryptoRF and customer algorithms can provide the
required authentication codes.
