Hiding of current consumption

Power analysis presents the typical example of successful attacks against trusted cryptographic devices such as smart cards or embedded devices. Nowadays, the popularity of Internet of Things (IoT) is growing therefore, designers sould implement cryptographic algorithms with countermeasures in order to defend against these types of attacks. The bachelor's thesis focus on the implementation of ultra-lightweight block cipher PRESENT and execution of Simple power analysis and Differential power analysis to reveal the secret key. Power analysis is firstly performed on cipher PRESENT with no implemented countermeasures and the attack was successful. Then the countermeasures were implemented and there were no leakage about the secret key. The countermeasures are using the hardware randomization of FPGA boards
