- Well, modern software assumes that the wire is anyway accessible to hackers. Hence, there should be encryption of data that gets sent on the modem. That way, the hacker can know what number you called, but after that, the data should be encrypted. In the past, when I used dial up modems to get on the net, there was some encryption as part of the ppp. And then, if you're browsing the web, etc, the web server may use its own encryption. But I doubt you're web browsing on an STM32 !kalyanswaroop– kalyanswaroop2022-01-12 17:28:23 +00:00Commented Jan 12, 2022 at 17:28
- @kalyanswaroop -- I might be wrong, but I think the OP is talking about the connection on the PCB between the STM32 and the modem IC, not the data leaving the modem IC to the remote endpoint.Dan– Dan2022-01-17 00:41:53 +00:00Commented Jan 17, 2022 at 0:41

`like _so_` - quote by placing > at start of line

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. smart-home), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
