Summary:The portability and various functions of mobile devices enable them to go deep into people's study, work and life. While it is convenient for people, mobile devices contain a large number of user’s private information, such as the user's personal property information, identity information and even the confidential information of enterprise etc. Side-channel attack is currently one of the most effective ways to steal private information of cryptographic devices thus the threat to mobile devices can be imagined. In this paper, the electromagnetic side-channel attack based on AES encryption algorithm on mobile device—PCM-9589F Multi-COM Board is studied. A new signal acquisition platform is designed, which solves the problem that the difficulty in locating the side-channel electromagnetic leakage signal of the mobile devices. In addition,using the time-frequency analysis and filter technology,we extract the encryption features of AES on PCM-9589F Multi-COM Board.
