digital signature: cryptographic verification of a download downloaded programmatically

Let's say I have an executable that runs on a client machine and requires downloading some updates on a regular basis. The solution uses TLS to communicate with the download server.

I would like to include the authentication of these updates before applying them, that is, that these updates are cryptographically signed.

My suggestion is to use asymmetric encryption, this requires distributing the public key with the executable that runs on the client machine. The download server will sign the updates with the private key. This would allow the client machine to use the public key to verify updates.

My questions:

  • Is this the general standard approach?

  • Will the public key usually be pressed with the executable that runs on the client's machine or would this be just a search through some REST API?

  • Does Apple (or others) implement a similar approach when verifying the downloaded file when they apply an update to the IOS platform?

I am not interested in the merits of TLS, etc.

wireless networks: interference between symbols versus digital modulation

so I'm a little confused here after my conference today. My teacher started by explaining what interference between symbols. and finished the conference talking about the different types of digital modulations. But now I'm confused with how they join. or your two different things?

Is ISI more about sending digital signals on a cable? Why ISI comes into play when doing say QPSK? I thought that the symbol signal sent in QPSK is just a sign of sin. or use this ISI?

someone please help because I am very confused … thanks in advance!

Location of the digital signature on a certificate

Where do I look for a certificate signature? For example, if I go to an HTTPS website and open its certificate through the padlock in the URL bar, I see the signature algorithm, the hash algorithm, etc. but I don't see the real digital signature that is encrypted using the private key and hash of the CA?

digital: low-end camera with electronic shutter and fast exposure

I need a camera module that allows me to electronically shoot a capture while supporting exposures in the range of 10 microseconds or less (1 / 100,000). I understand that this would be a dark exposure under normal lighting, but I have the ability to accurately measure the bright strobe lights along with the capture. The purpose is to obtain images of objects that move quickly (90 m / s MAX) to obtain position and velocity data.

I am an engineer with experience in electronics and software, but without knowledge of digital imaging hardware. I need to find a camera module that meets my requirements, while being low enough to integrate it into a personal project. I have searched for everything I can think of and cannot find anything other than a laboratory device that costs thousands. I don't need specific product recommendations if that is not allowed here, but some help on where or how to find what I am looking for would be an acceptable answer.

Edit: After reading a little, I now understand that an exposure of 1 / 100,000 does not mean that my image will be captured in 1/100000 of a second. That said, I need a complete capture in that period of time.
