Atmel launches next-generation CryptoAuthentication device


Atmel becomes first to ship ultra-secure crypto element enabling smart, connected and secure systems.


Just announced, the Atmel ATECC508A is the first device to integrate ECDH (Elliptic Curve Diffie–Hellman) security protocol — an ultra-secure method to provide key agreement for encryption/decryption, along with ECDSA (Elliptic Curve Digital Signature Algorithm) sign-verify authentication — for the Internet of Things (IoT) market including home automation, industrial networking, accessory and consumable authentication, medical and mobile, among many others.

Atmel’s ATECC508A is the second integrated circuit (IC) in the CryptoAuthentication portfolio with advanced Elliptic Curve Cryptography (ECC) capabilities. With built-in ECDH and ECDSA, this device is ideal for the rapidly growing IoT market by easily providing confidentiality, data integrity and authentication in systems with MCU or MPUs running encryption/decryption algorithms (such as AES) in software. Similar to all Atmel CryptoAuthentication products, the new ATECC508A employs ultra-secure hardware-based cryptographic key storage and cryptographic countermeasures which are more secure than software-based key storage.

This next-generation CryptoAuthentication device is compatible with any microcontroller or microprocessor on the market today including Atmel | SMART and Atmel AVR MCUs and MPUs. As with all CryptoAuthentication devices, the ATECC508A delivers extremely low-power consumption, requires only a single general purpose I/O over a wide voltage range, and available in a tiny form factor, making it ideal for a variety of applications that require longer battery life and flexible form factors.

“As a leader in security, Atmel is committed to delivering innovative secure solutions to the billions of devices to be connected in the IoT market,” explained Rob Valiton, SVP and GM of Atmel’s Automotive, Aerospace and Memory Business Units. “Atmel’s newest CryptoAuthentication IC is the first of its kind to apply hardware-based key storage to provide the full complement of security capabilities, specifically confidentiality, data integrity and authentication. We are excited to continue bringing ultra-secure crypto element solutions to a wide range of applications including IoT, wireless, consumer, medical, industrial, and automotive, among others.”

Key security features of the ATECC508A include:

  • Optimized key storage and authentication
  • ECDH operation using stored private key
  • ECDSA (elliptic-curve digital signature algorithm) sign-verify
  • Support for X.509 certificate formats
  • 256-bit SHA/HMAC hardware engine
  • Multilevel RNG using FIPS SP 800-90A DRBG
  • Guaranteed 72-bit unique ID
  • I2C and single-wire interfaces
  • 2 to 5.5V operation, 150-nA standby current
  • 10.5-kbit EEPROM for secret and private keys
  • High-Endurance Monotonic Counters
  • UDFN, SOIC, and 3-lead contact packages

In the wake of recent incidents, it is becoming increasingly clear that embedded system insecurity impacts everyone and every company. The effects of insecurity may not only be personal, such as theft of sensitive financial and medical data, but a bit more profound on the corporate level. Products can be cloned, software copied, systems tampered with and spied on, and many other things that can lead to revenue loss, increased liability, and diminished brand equity.

Data security is directly linked to how exposed the cryptographic key is to being accessed by unintended parties including hackers and cyber-criminals. The best solution to keeping the “secret key secret” is to lock it in protected hardware devices. That is exactly what this latest iteration of security devices have, are and will continue to do. They are an inexpensive, easy, and ultra-secure way to protect firmware, software, and hardware products from cloning, counterfeiting, hacking, and other malicious threats.
