Atmel extends its cryptoAuthentication
family supporting AES
Atmel has announced an extension to the Atmel CryptoAuthentication
family, the ATAES132 devices. These new devices offer secure
data storage using the AES (Advanced Encryption Standard)
authentication for industrial, consumer, computing and embedded
applications with flexible key management features and secure
counters. AES is a symmetric-key encryption standard adopted
by governments and cryptographic experts around the world.
These security features are available in two devices compatible
with standard serial EEPROMs, one supporting I2C and the
other supporting SPI, allows system developers to add security
to existing systems without retooling their printed circuit
board. This direct replacement can extend the life of a
system's architecture by including security features within
the hardware to make the system more secure than software
implementations. The new secure devices also extend a current
system's security into the future with the AES-CCM (AES
in Counter and Cipher block chaining modes with message
authentication code) authentication.
All Atmel ATAES132 devices support 2.5V to 5.5V supply
voltages and consume less than 250nA standby/sleep current.
The Atmel ATAES132 development kits can be plugged into
any Atmel AVR or ARM-based development kits for a complete
project solution.
"There is a current void in the consumer, medical
and computing sectors for increased security in these micro
controller-based applications," said Kerry Maletsky,
cryptographic product line director, Atmel Corporation.
"Atmel helps fill this void by enabling developers
to simply replace their serial EEPROM with the new ATAES132.
These devices offer hardware protection for keys and data
to help system developers easily integrate a higher level
of trust in their system. 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."
