The address of this chip can be modify in the configuration. You can communicate with this chip by I2C. Third, the library wrote in C is very big and complete, so you have to read the documentation of the functions that you will use before.įour, the library wrote for this chip not work for Arduino UNO, but It added the functionalities need it to work with Arduino UNO. So be careful when you will lock the Config Zone and the Data Zone.

Second, when you use this chip you need to lock its configuration and it is impossible to modify the configuration of the chip if it is locked. But no problem for this, the datasheet of the previous version is available on Internet Datasheet Complete ATECC508A. I will wrote an article about the communication of two object next time.įirst, the documentation of this chip is under NDA so you won't find it in complete on Internet.

In this article, I will explain you how to use the Arduino UNO with the ATECC608A. Now I will explain you how I implemented this abstract picture with an Arduino and a Atecc608a chip.

Utilization of encrypted data between two or more IoT object.

So I decided to work on a project that use security layer for communication between two IoT object.ĭuring a communication between two IoT Object, multiple attacks can be exist : Man Of the mild, Copy of information and more. He showed us chips (less than 0.60$) that could add a layer of security to these objects.Īfter this demonstration, I tried to find some Open source project that add security layer to IoT object but I never found it. He explained us that 'Security' for 'Industrial' is not the main problem.

He showed us with his own PC and a Bluetooth sniffer that every command sent by the smartphone are the same each time and it is very simple to copy this command and sent it with your smartphone. This sentence make him smile and he modified the sentence 'This padlock is the worst padlock ever build !'. On the padlock, a sentence said 'This padlock is most secure than a key padlock !'. I showed us a padlock that can be open with your smartphone by Bluetooth. During my studies, I get a conference with a specialist on IoT Security who showed us that Industrial does not use Security in their IoT object. I work in the domain of the CyberSecurity and as everyone I loved programming and electronics. This version is the most advanced chip and got functionalities that old version does not have (For example : AES module, IO protection module. Why did I decide to use the last version and not the previous version ? Before this version, there was 'ATSHA204A' and the 'ATECC508A'. This chip has been designed by MicroChip and it is the last version of 'CryptoAuthentication chip'. In this article, I will explain you how to use a micro chip called 'ATECC608A' that provide multiple security tools. Your selected library will be listed, where you can select a version (I used v3.1.0 of FastLED and v1.1.3 of NeoPixel) and click “ Install“.This is my first Instructables Article so I hope it will be interesting for all of you. I prefer FastLED, but I leave that choice up to you.

In the window that pops up, enter either “ neopixel” or “ fastled” in the filter field, and press ENTER for the library you’d like to use.

The Arduino IDE can be dowloaded from their website for free – I have never used their online IDE, so please stick with the regular one that you install on your computer.Īfter starting the Arduino IDE, which may take a bit, go to the menu and choose “ Sketch” “ Include Library” “ Manage Libraries“. The Arduino IDE has come a long way since I’ve written the original article, and installing a library has become much easier.

I do recommend reading the original article “ LEDStrip effects for NeoPixel and FastLED“, but it is not required since I will be posting the full code for both libraries. With the Arduino Uno R3 though, this works great with FastLED. This way you have a choice – it’s up to you. FastLED might be more advanced, but NeoPixel takes up less memory. However, as with the original article, I wanted this to work for both. Well, I have to admit that I have become a FastLED fan – it’s become much more mature and advanced than NeoPixel. Challenge 5 - Variable surviving a reset.Challenge 4 - Initiate the start of a new effect.
