Secure Boot use case with ATECC608A
Why would you use a secure element for Secure Boot ?
This solution is archived and will no longer be updated. We recommend that you use the TrustFLEX ATECC608A-TFLXTLS instead.
Very often the intellectual property (IP) of an embedded product lives within the code of the microcontroller. In today's market place, it only takes a few weeks to extract that code despite the usage of traditional "code protect" features. At a moderate expense, many third party options are widely available on the internet who are capable to obtain HEX files from the microcontroller. This type of conterfeit puts in danger companies IP and could consequently lead to significant revenue loss or open various backdoors to malicious firmware.

20 Years of Experience in Secure Provisioning
Microchip is here all the way through.
Trust cannot rely only on the device but also on the manufacturing process. Exploiting third party weaknesses is one of the top targets for hackers. Isolating keys and secrets from manufacturing is equally vital. Customers can leave this burden to Microchip's secure factories and leverage our trusted provisioning service already used by thousands of companies.
