Cwa-documentation: Key exchange

[AndiLeni]

Hello,
I wanted to ask if there is a document that explains the exchange between two smartphones in more detail.
The document for the solution architecture describes very nicely what happens when you want to upload your data, but I'm looking for information that explains the exchange in more detail.
The information how the keys are generated, when they are generated, how they look like and so on would be very interesting.
Is there perhaps also a document here which describes the exchange between mobile phones step by step?

Kind regards
Andreas

Hi @AndiLeni ,

this time a quicker answer :) Google has a very good FAQ page for this information, including details about cryptographics. I hope this is what you're looking for.

@tkowark thanks for the quick response :)
And thanks for the links.
I thought there might be additional documents from the Corona-Warn-App that explain this function in more detail or in a more specific way.
I will definitely have a look at the document and get back to you if some questions araise.

Kind regards
Andreas
