Research on a Consensus Mechanism-Based Anti-Runaway Scheme for Digital Trunking Terminals

Summary:

How to effectively prevent the digital trunking terminal from running out of control through technical means is one of the security and confidentiality technologies that needs to be solved urgently in the large-scale application of the digital trunking communication system.As an important mode widely used in the trunking communication system, the pass-through mode has the characteristics of non-central distributed networking, so the traditional solution cannot effectively realize the real-time anti-runaway of the digital trunking terminal in the pass-through mode.Through the analysis, the core problems of "who will judge" and "how to judge" in the terminal runaway prevention in the pass-through mode are put forward.Practical Byzantine Fault Tolerance Algorithm in Block Chain to design a digital cluster terminal anti-runaway scheme that can be used in pass-through mode.

In recent years, digital trunking communication systems have been widely used in special users such as the party, government, and military, as well as major industry users such as transportation, energy, airports, and ports.Due to the particularity of its application scenarios and the nature of users, the security of the system is particularly important.As an important branch of the security concept of the digital trunking communication system, the problem of preventing the loss of control of the trunking terminal is closely related to the security of the system operation.At present, the cluster terminals used by the party, government, military and other special user equipment are mostly security password equipment, and the level of equipment management and control is relatively high.
