Key heterogeneous defense method

Abstract

The invention discloses a key heterogeneous defense method. According to the technical scheme adopted by the invention, the method comprises the steps of initiating a service request by a user on a user side according to the needs of the user; after receiving the user service request information, applying to a buffer pool for encryption by a forwarding control terminal; returning two encryption modes to a distributor and synchronizing a decryption mode of one of the encryption modes to executive bodies which receive the information by the buffer pool; transmitting the information encrypted byadopting the encryption mode provided with the decryption mode and the other encryption mode to the executive bodies by the distributor and repeating the method to generate 2n encryption and decryption modes, where the n is the number of executive bodies; after receiving the encrypted information, decrypting the information to generate result information, encrypting the result information and returning to a voter by the executive bodies; and making a vote according to a voting algorithm and returning the result to the user by the voter. The method disclosed by the invention has the advantagesthat while attackers are confused, the executive body non-external attack abnormality caused by the delay of the executive body decryption mode after the encryption modes are transformed is solved atthe same time.

Description

technical field [0001] The invention relates to the field of network security, in particular to a key heterogeneous defense method. Background technique [0002] In today's network environment, the Web service system, as an important service bearing and providing platform, is a virtual representative of the government, enterprises and individuals on the Internet, which brings together massive data resources, such as user information, enterprise data, financial finance, business secrets, The importance of intellectual property rights, customer order information, etc. is self-evident. Therefore, the Web server becomes the main attack target of network hackers. Network hackers use various channels, various attack tools, and various deceptive means to obtain the information they want. [0003] Under normal circumstances, the encryption method of the dynamic heterogeneous defense system is only ordinary dynamic encryption, and the encryption method is fixed within a certain per...

Problems solved by technology

[0005] In view of the deficiencies in the above-mentioned prior art, the object of the present invention is to provide a key heterogeneous defense method to prevent the attacker from repeatedly attacking the probing rule, the attacker crossing the voting device to attack, and the problem of time delay during dynamic encryption. At the same time, the clock controller can also solve the problem of excessive cache, ensuring that users enjoy safe and stable web services
