Differential Power Analysis Attacks

—cryptographic devices have found their way into a wide range of application and the topic of their security has reached great research importance. It has been proved that encryption device leaks information, which can be exploited by various attacks such as power analysis, timing analysis and electromagnetic radiation. Differential power analysis is a powerful and efficient cryptanalytic technique which extracts information on secret keys by monitoring instantaneous power consumption of crypto processor and collecting the traces over a series of acquisitions.. The focus of our project is to analyze how a crypto-processor (a smart card) implementing AES reveals information against Differential Power Analysis attacks.
