Encrypted OTA
Posted: Tue Jan 17, 2017 11:56 amThe subject resumes my question pretty well. I'd want to put AES (or other strong encryption) on the OTA function. The problem is that everything is sent unencrypted. If I sniff with Wireshark I can download the program, even if OTA is protected by password. So, someone could sniff and introduce a malicious program or get my program, modify it and upload it. My question is, must I make myself a function to create a secure server, is it integrated or can I download it? Which library can I use for decryption?
