Today, embedded electronic systems are everywhere, controlling every aspect of everyday life both in professional and in private environments. Most of them manage private information or sensitive data and implement some cryptographic algorithms with the aim of protecting private information from stealing. Even if the algorithms themselves can be considered secure, they can be broken by physical observation of certain properties of the electronic devices, such as the current absorbed or the time taken to execute the algorithms. This is how Side-Channel Attacks take place. These kinds of exploits are very effective ways to gain access to secret information hidden in the embedded systems.
