The present disclosure provides a message processing method and device, equipment and storage medium, comprising: in response to receiving a to-be-processed message, extracting quintuple information from the to-be-processed message; matching the quintuple information with the index key of the session table to determine the type of the to-be-processed message, wherein the index key of the session table is constructed based on the quintuple information of the established session; in response to the type of the to-be-processed message being a first packet, matching the quintuple information with the index key of the association mapping table to determine whether the to-be-processed message is an associated session of the main session, wherein the index key of the association mapping table is constructed based on the IP address and port information obtained by parsing the application layer of the control channel message of the multi-channel protocol, and the main session is the session of the control channel; in response to the to-be-processed message being an associated session of the main session, performing forwarding processing on the to-be-processed message.

An anti-pseudo base station method and apparatus, and a computer-readable storage medium are provided. The anti-pseudo base station method includes: sending, by a base station, first anti-pseudo base station capacity information to a mobile terminal, wherein the first anti-pseudo base station capacity information is used for identifying an anti-pseudo base station capacity of the base station. According to the solution provided by the embodiments, the terminal can be informed of the anti-pseudo base station capacity of the base station conveniently, so as to execute a corresponding authentication and key agreement and distribution process conveniently, and therefore improve network security.

The invention discloses a code verification method and device of a train operation control system, equipment, a medium and a product, and relates to the technical field of network security, and the method comprises the steps: carrying out the semantic analysis of a network security demand specification document, extracting the network security demand structured information, and determining a target code verification strategy according to the network security demand structured information; determining an assertion specification and a code insertion position of the assertion specification according to the target code verification strategy and the network security demand structured information, and inserting the assertion specification into the original network communication code according to the code insertion position to obtain a to-be-verified network communication code; and verifying the to-be-verified network communication code by using the target code verification tool according to the assertion specification to obtain a code verification result. According to the invention, the code level verification effect on the network communication code of the train operation control system is realized, the network security of the train operation control system is improved, and the possibility of occurrence of network potential safety hazards is reduced.
