Abstract:

With the integrated development of the 5th generation mobile communication technology and artificial intelligence technologies, smart terminals have been widely applied across various industries, leading to frequent security incidents and multiple threats. This paper first analyzes the development dynamics of mobile terminal security at home and abroad, then systematically examines the key security technologies for intelligent terminals from five core dimensions: chips, operating systems, applications, data and privacy, and artificial intelligence. It further delves into the evolutionary processes of security technologies in chips, operating systems and applications. Finally, it dissects the current challenges faced by the security of China’s intelligent terminals from the aspects of standards, technologies, industries and applications, proposing development recommendations to provide practical references for advancing smart terminal security technologies in China and offering technical support for building a trusted digital infrastructure.

Key words: smart terminal security, chip security, OS security, application security
