    13.56 MHz RFID Reference Design Offers a True 64-bit Encryption Engine

Atmel Corporation launched its Keen+ reference design for the development of secure, 13.56 MHz logic-based, passive RFID, close proximity applications.

This AT88SC-ADK2 Keen+ development kit includes:

1. Atmel's Crypto Evaluation Studio tool suite
2. An application development board
3. CryptoRF samples in both tag and smart card form
4. A USB cable
5. A quick start guide

The Crypto Evaluation Studio tool suite has a menu-driven, graphical user interface for CryptoRF configuration and testing, plus development libraries and code examples for host-side cryptographic operations required for secure communication.

The application development board includes:

1. AT88RF1354 host-reader chip
2. An Atmel AVR flash microcontroller
3. USB connectivity to PC and power

The AT88RF1354 host reader performs RF communication, packet formatting, decoding, and communication error checking and is based on ISO/IEC 14443-2 Type B signal modulation scheme and ISO/IEC 14443-3 Type B frame format. The features are,

1. Data is exchanged half duplex at a 106k bit per second rate.
2. A two-byte CRC_B provides communication error detection capability.
3. It can be used with both RFID transponders and contactless smart cards.
4. Is compatible with 3.3V and 5V host microcontrollers with two-wire or SPI serial interfaces.

CryptoRF Devices has the following features:

1. A 13.56 MHz RFID logic-based transponder with a 64-bit embedded cryptographic engine; four sets     of non-readable, 64-bit authentication keys; four sets of non-readable, 64-bit session encryption     keys; and up to 64 Kbits of memory.
2. Sixteen individually configurable sectors can be customized to allow different levels of access,     including read and write, read-only, and one-time-programmable.
3. CryptoRF transponders have both mutual authentication and, uniquely, a dual authentication      capability that allows two completely independent users with separate authentication keys to access      the same section of the memory.
4. Because these transponders generate a unique identity for each individual transaction they can be      used for multi-use cash transactions (bus passes, vending programs, loyalty cards), secure      building access, authenticating consumables for medical, printing and consumer electronics.

The Keen+ kit includes a free library of simple API calls that execute the most complex host operations; including,

1. Building a software model of the host-side cryptographic engine,
2. Computing challenges,
3. Performing data encryption and decryption,
4. Computing encrypted passwords and message authentication codes,
5. And keeping the host model of the cryptographic engine in synchrony with that in the device

CryptoStudio Development Environment Offers GUI Driven Development.

Pricing, Packaging & availability:

1. Atmel's Keen+ RFID Development Kit, including reference designs and software is available now for     $99.95.
2. AT88RF1354 host RFID reader ICs are available in 6mm x 6mm, 36-pin QFN packages now for     US$1.07 in quantities of 25,000 units.
3. CryptoRF RFID transponders are available in tag form with prices for the smallest density starting at      US$0.40 in quantities of 25,000 units.
