Abstract：Wireless communications have gone deep into every aspect of peoples work and lives, but its security cannot be overlooked. Due to the openness of the physical channel in wireless communications, modulated signals carrying important information are completely exposed in free space. However, there are few protective measures for the modulated information at the physical layer in current wireless communication systems so that an attacker can use blind signal processing technique to recover important information of signals and make legal communications suffer huge security threats. The paper focuses on the modulated signal information security risk analysis in wireless communications. Recovery methods of important modulated signal features in noncooperative communications, including instantaneous features and constellation diagram, are introduced first, then qualitative risk assessments for the key features of modulated signals are made by simulating analysis.
