Time-sensitive network-oriented time synchronization architecture, security method and device

The invention discloses a time-sensitive network-oriented time synchronization architecture, security method and device, and the architecture comprises a master clock source system which is used for providing time information for a directly connected slave clock by adopting a dynamic heterogeneous redundant security architecture; the slave clocks are subjected to time synchronization with the master clock source system step by step in a hierarchical form according to the network topology; wherein the master clock source system comprises a master clock source controller, a heterogeneous master clock source resource pool, a current master clock source and a master clock source online detection set. The method comprises a master clock source election stage, a synchronization stage, a master clock source verification stage and a master clock source agile switching stage. According to the architecture provided by the invention, the election efficiency, the switching speed and the reliability of the main clock sour
