Atmel launches first EEPROM device with AES-CCM authentication
1 min read
Atmel has extended its CryptoAuthentication product portfolio to include the ATAES132 EEPROM device, the first with advanced encryption standard Counter with CBC-MAC (AES-CCM) authentication. Designed for industrial, consumer, computing and embedded applications, the device offers a large storage capacity, rich feature set and true random number generation.
The security features are available in two devices compatible with standard serial EEPROMs; one supporting I2C and the other supporting SPI. According to Atmel, this allows system developers to add security to existing systems without retooling printed circuit boards. The direct replacement is designed to extend the life of a system's architecture by including security features within the hardware to make the system more secure than software implementations.
"There is a current void in the consumer, medical and computing sectors for increased security in microcontroller based applications," claimed Kerry Maletsky, Atmel's cryptographic product line director. "Atmel helps fill this void by enabling developers to simply replace their serial EEPROM with the new ATAES132. These devices offer world class hardware protection for keys and data to help system developers easily integrate a higher level of trust in their system."
Consuming less than 250nA standby/sleep current, the ATAES132 development kits can be plugged into a range of Atmel AVR or ARM based development kits and support 2.5 to 5.5V supply voltages. Maletsky claims features like non reversible monotonic counters and the ability to securely move keys on and off the chip provide a level of system flexibility not previously available.
