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.
