PRESENT algorithm was designed as a lightweight block cipher algorithm in 2007. PRESENT is suitable for the se- curity of encryption in the environment of the Internet of Things（IoT）. This paper studied PRESENT algorithm in-depth, and proposed two power analysis attack points. It introduced power analysis attacks on PRESENT and its implementation process in detail. The experimental results show that unprotected PRESENT encryption system can not resist the first-order differential power analysis attack. The researches c...
