Information security guarantee method of internet of things sensing device cloud simulation system

The invention discloses an information security guarantee method of an internet of things sensing device cloud simulation system. The method mainly solves the problem that an existing Internet of things sensing device cloud real-time simulation system is not safe. According to the technical scheme, the method includes the steps that 1, verification is carried out before an Internet of things sending device has access to a cloud real-time simulation system so as to guarantee legality when the Internet of things sending device has access to the cloud real-time simulation system; 2, encryption, transmission in timed and real-time modes, decryption, comprehensive processing of verification are carried out on data in the real-time data transmission process, so that privacy in the data transmission process is guaranteed; 3, when a cloud application service program has access to a cloud simulation node, access control verification is carried out on the cloud application service program so as to guarantee that illegal access of the cloud simulation node is avoided. The method improves safety of the Internet of things sensing device cloud real-time simulation system, and can be used for cloud computation and the internet of things.
