How does communicaton over internet work?
When user writes messages from one computer device such as PC/phone/tablet or laptop he sends
data. To make sure that the data cannot be seen by other people the data is encrypted with a secret
key which either both users have or a server and user have thus making it harder for
hacker/malicious user to read the same data.
What’s compromised key atack?
Compromised key atack is when an atacker
manages in any way to
determine/predict/steal the secret key used
to encrypt data between two or more devices
which makes the encrypton useless as he can
read all the data that is sent between those
devices without anybody knowing except the
malicious user.
