In modern times as data becomes more secure with encryption, there are certain attacks that you may not be aware of. One specific type of attack is called a side-channel attack.

Side-channel attacks rely on measuring tendencies and frequencies of your computer to establish patterns that can extract private information from your machine.

Side-channel attacks or SCA, monitor your power use and electromagnetic emissions during cryptographic operations. Due to the low cost and simplicity of these attacks, multiple side-channel techniques can be used. Here is a list of the different techniques:


Different ways to help prevent these attacks have been introduced but not widely implemented. A few ways to try to prevent these attacks are:

Once your keys are established, hackers could gain access to your data and could increase your chances of corruption or removal.
