Safety analysis method and system based on protocol state

The invention discloses a security analysis method and system based on a protocol state, and relates to the technical field of protocol security protection, and the method comprises the steps: building a node traversal table, carrying out the scanning analysis of the node traversal table according to a protocol triggering sequence rule, determining a first security evaluation factor of a protocol stack, and based on a protocol normal application rule, carrying out the scanning analysis of the node traversal table; determining a second security evaluation factor of each protocol, determining the credibility of the second security factor based on the first security factor, correcting the second security factor based on the credibility, and determining the security state of the protocol according to the corrected second security factor, thereby achieving the analysis of the state of the protocol, and improving the security of the protocol. Therefore, the security of the protocol can be accurately determined. 本申请
