specific Embodiment

[0037] In order to illustrate more clearly, the specific embodiment of the present invention is as follows:

[0038] Such as figure 2 As shown, a data security interaction method based on host feature confusion is characterized in that it includes the following steps:

[0039] (1) Before communication, the system uses the fingerprint information of the host to construct a communication byte substitution table T, sends it to the source and the sink, and stores it in the databases of both parties. The communication byte substitution table structure consists of four columns, the first column is the primary key index, the second column is the host fingerprint information, the third column is the data content, and the fourth column is the description information of the mapping;

[0040] Wherein, the host fingerprint information stored in the database includes: operating system architecture type, system version number, running service type, service interface number, browser type, ...

Abstract

The invention relates to a data security interaction method based on host feature confusion, which involves in an open network environment, the communication parties use the fingerprint confusion pool of the local host to expose the interactive data packets carrying different host fingerprint information according to predefined rules. To the other party, the method of realizing data interaction. The invention pre-stores the host fingerprint communication byte substitution table at both ends of the communication, and generates a plurality of heterogeneous containers to dynamically build a host fingerprint confusion pool. The information source triggers the corresponding heterogeneous container in the confusion pool according to the data request, and generates a specific host carrying The data packet of the fingerprint information is replied, and the sink analyzes and replies the fingerprint information, and the final data is obtained by using the substitution table. The present invention hides the interaction data in the fingerprint features of standard and common various protocol hosts, does not represent any business information, and ensures the safe data interaction between the communication parties.

Description

technical field [0001] The present invention relates to the technical field of safe communication between a sending and receiving party in an open network environment, in particular to a data security interaction method based on host feature confusion by constructing a heterogeneous container pool. Background technique [0002] In an open network environment, communication is faced with many defects. Information transmission passes through many intermediate nodes. These nodes are uncontrollable to users, have high risks, and are vulnerable to monitoring by illegal third parties. When data passes through malicious nodes and links, Faced with the risk of information being sniffed, extracted, tampered with and blocked. [0003] At present, there are various ways of secure network communication, including authentication of identity, encryption of data, and construction of a virtual private network, etc., but these methods still have the following problems: [0004] (1) Protecti...
