Abstract: Disclosed are a method and apparatus for implementing security of broadband bus architecture in industrial internet field. The security of the access process can be guaranteed by encrypting data transmitted between the bus terminal and the bus controller; the operation of the entire system can be prevented from threat of abnormal data by performing security detection on the acquired data; it can be easy to treat abnormal conditions of the transport rule by the bus controller by monitoring and reporting the transport rule of the data flow over the bus by a bus terminal; and the reliability of the transmission process may be improved by interleaving the to-be-sent data at the bus controller and the bus terminal; the time delay of the data transmission resulting from the addition of the interleaving processes can also be reduced to have high transmission rate.

Abstract: The invention discloses a method for deep data inspection over an industrial internet field broadband bus, the method including: obtaining, by a first node, a message to be transmitted; judging, by the first node, whether a bus device address in the message to be transmitted lies in a preset range of bus device addresses; and if the bus device address lies in the preset range of bus device addresses, then transmitting, by the first node, the message to be transmitted to a processor of the first node. The first node only forwards the message to be transmitted, lying in the preset range of bus device addresses to thereby improve the security of transmitting the message.

Abstract: The invention discloses a method for implementing a real-time industrial internet field broadband bus, the method including: determining, by a bus controller, the number of bus terminals connected therewith; and allocating, by the bus controller, time slices for the bus terminals according to the number of bus terminals, and transmitting, by the bus controller, the time slices to the bus terminals so that the bus terminals operate in the allocated time slices. Moreover data are transmitted in the bus system by removing Ethernet/IP message header information to thereby reduce the length of the message, and shorten a transmission delay and a bus scan periodicity so as to improve the real-time characteristic of the bus system.
