I am wondering whether some severe accidents due to sharing a secret key exist in real world.
A group of users or a company typically share a secret key to decrypt some shared encrypted data possibly stored on cloud storage.
However, each user has to be responsible for secret key management. I think not all of the users do that propery. Is anyone aware of some severe accidenst where the shared secret key had been stolen and all the entire data was stolen as well?
I am sorry if this topic is not related to this website.
