Atmel CryptoRF
Atmel's CryptoRF devices use a ISO1443 based, 13.56Mhz radio system, a strong encryption to produce low cost embedded security devices to prevent theft, counterfeiting, and fake product reproduction.Benefits claimed by Atmel include:
- Offers hardware security, which is superior to any software solution
- Combines hardware security with key diversification, therefore delivering a superior security solution
- A hardware security solution makes attacks non-trivial
- Key diversification scheme limits any attack to only one unit
- Shorter application development cycle time
- Atmel is #1 in hardware security
The underlying radio system is based on ISO1443-B, and is royalty free. A range of up to 10cm is typical.
For example, an AT88SC02040CRF can have a range of 8-10cm implemented as a smart card, 1-3cm implemented as a 17mm diameter RFID tag, and 10-15mm as a 10x20mm RFID tag.
Typical applications are:- Production Authentication
- Public Transportation
- Anti-Cloning
- Driving License
- Track and Trace
- E-Purse
- Energy Meters
- Health Cards
- Campus Cards
- Logistics Management
- Secure Access Control
- Anti-counterfeiting
- Identification
- Insurance Cards
