ATSHA204A and ECC508A Security ICs

Microchip presents world-class embedded security solutions, ensuring trust for every system design

Image of Microchip ATSHA204A and ECC508A Security ICsIn today's vast IoT interconnected world, the need to provide greater security within a customer's product or system is quickly becoming a strict requirement. From one application to another, security requirements can vary drastically: to prevent unauthorized entry, theft of software/hardware intellectual property, data, or communications services. One such system is access control to building. Microchip brings together both cryptographic and non-cryptographic devices to build a total solution. Trust is what security is all about today. Microchip security products make "trust" easy to embed in any system. Flexibility, advanced features, innovative cost-effective architectures, and ultra-secure hardware defense mechanisms make Microchip hardware-based security devices an ideal way to add trust, by design.

The Microchip ATSHA204A is a full-turnkey security device. It includes a 4.5 kB EEPROM divided into sixteen slots. This array can be used for storage of keys, miscellaneous read/write, read-only, password or secret data, and consumption tracking. Access to the various sections of memory can be restricted in a variety of ways and then the configuration locked to prevent changes. Microchip’s ECC508A device offers Zero Touch for AWS IoT Secure Provisioning Platform for AWS IoT, offering the industry’s first end-to-end security solution for Internet of Things (IoT) devices that connect to the Amazon Web Services’ (AWS) cloud. The product was developed jointly with AWS and will help IoT devices comply quickly and easily with AWS’ mutual authentication IoT security model. The new security model states that a device must use mutual authentication with a remote server to be authorized on the AWS cloud. .

ECC508A Features  
  • Seamless integration of AWS IoT to any IoT product
  • As easy as soldering a pre-provisioned ECC508 device on PCB
  • Developed collaboratively with AWS to comply with AWS IoT security policies
  • No human intervention, automatic self-onboarding to AWS servers upon initial connection
  • Tamper-resistant, secure element for strong authentication through key storage and secure execution environments
  • Forever secret, internally generated device private keys to facilitate manufacturing logistics and chain-of-trust management
  • Flexible packages and interface communications options
  • Key provisioning for large-scale manufacturing made easy
  • Options to root a chain of trust with a self-signed root or a well-recognized certificate authority
ATSH204A Features
  • Crypto element with protected, hardware-based key storage
  • Superior SHA-256 hash algorithm with message authentication code (MAC) and hash-based message authentication code (HMAC) options
  • Guaranteed, unique, 72-bit serial number
  • Secure, symmetric authentication device host and client operations 
  • Best-in-class, 256-bit key length; storage for up to sixteen keys
  • Internal, high-quality random number generator (RNG)
