I'm considering the use of an Arduino in a project I'm on but a question is still open.
The Arduino will be collecting data and, once in a while, will send them to a server. I would like to be able to secure the data transmission.
I do know that the Arduino has not enough processing power to handle HTTPS encryption but I'm wondering if a solid alternative can be used here.
What's your opinion?
the best you can use in arduino is xxtea encryption. is fast but not super secure
Check out the Microchip PIC 18x and 24x series uCs.
