The Research on Embedded Real-time System Security Issues in Mechanical Control

Embedded real-time systems are facing more and more security problems. Malicious attacks on the system from suspicious or malicious code and the change of system hardware state could lead to system exception, resulting in system reliability and security deteriorated. This paper summarizes the characteristics of embedded real-time system and its special requirements for security, analyses security problems faced by embedded real-time system and defects of programming languages. And then put forward methods to improve the safety of embedded real-time system, providing a new security the idea for solving the embedded real-time system security.
