Embodiment Construction
[0062] The implementation steps of Internet of Things operation instruction signature and encrypted transmission are described below in conjunction with the accompanying drawings:
[0063] figure 1: Explain the process of the Internet of Things operation instruction control center encrypting and transmitting the operation instruction to the remote automatic control device. First, the Internet of Things operation instruction control center generates the operation instruction Z to be sent to the remote automatic control device identified as Bi, and the Internet of Things operation instruction control The central encryption system extracts the ciphertext and summary information LTi of the "key seed" three-dimensional matrix Ti element corresponding to Bi from the key database, see: the table in Article 9 of the manual, and in the encryption card chip, LTi The formed matrix LGi elements are mapped to the elements of the matrix TT, and the elements to which the matrix TT is mapped...

The invention discloses a realizing method for internet of things based on a trusted operation order remote-control self-control device. The realizing method comprises the following steps: embedding an SD card into a remote self-control device, inserting an encryption card into a server at an operation order control center end of the internet of things, respectively establishing an encryption system at an internet of things operation order control center end and each remote self-control device end by adopting a symmetric cryptographic algorithm, forming a three-dimensional matrix through a secret key seed to establish a combined secret key generating algorithm, generating a symmetric secret key in real time, changing once at a time, encrypting the operation order into a ciphertext through the internet of things operation order control center end encryption system, sending to the remote self-control device end, after performing decryption and integrity verification on the received operation order ciphertext through the remote self-control device encryption system, determining whether to perform relevant operation of the operation order, thereby realizing trusted remote control of the internet of things operation order control center to the remote self-control device.
Description
Technical field: [0001] The invention relates to the field of information security of the Internet of Things in which an operation instruction remotely controls a remote automatic control device.
