The invention discloses a dynamic label generation and sharing mechanism method and device for source and path verification, and the method comprises the steps: configuring a control server for each management domain, including configuration of routing equipment information, label generation and label distribution; the label distribution is used for writing end node sharing and routing node sharing routing equipment dynamic labels of the routing nodes into the routing equipment nodes in advance, and distributing the routing equipment dynamic labels of neighbor routing equipment of each routing node to each routing node; before each communication, a source user and a target user obtain a routing device dynamic label and a source user session dynamic label and a target user session dynamic label based on label distribution of a local domain control server, and verification code addition and verification are realized based on the routing device dynamic label and the user session dynamic label. The problems that in the source and path verification process during communication, the calculation and communication overhead is large and the reliability is not high when the label for the device identity is generated and shared between the user and the routing device are solved.
Description
technical field [0001] The invention relates to the technical field of computer networks, in particular to a dynamic label generation and sharing mechanism method and device for source and path verification. Background technique [0002] The Internet has the characteristics of "simple core and complex edge", which leads to the untrustworthy behavior of its transmission path nodes, which brings security problems such as routing hijacking and traffic eavesdropping. Reliable and trusted communication between Internet source and destination nodes depends on the mutual trust between source and destination nodes and intermediate routing nodes, and the lack of authenticity verification of intermediate routing nodes in the initial architecture design of the Internet provides path deception. Favorable conditions. Attackers can change the transmission path of data packets, implement transmission path tampering, traffic eavesdropping and other attacks. As long as the data packets are ...
