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.
