A method and system for secure data transmission combining multi-mode communication and aont transformation

Abstract

The present invention provides a method and system for secure data transmission combining multi-mode communication and Aont transformation. The method includes: the client determines the data information to be transmitted; Aont mapping transformation is performed on the data information to be transmitted to generate the first transformation Data; split the first transformation data to generate multiple data blocks; encrypt some of the data blocks in the multiple data blocks to generate encrypted data blocks; the client selects the most secure communication link among the multiple communication links One channel transmits encrypted data blocks to the receiving end, and the other communication links transmit unencrypted data blocks to the receiving end; the receiving end receives encrypted data blocks and unencrypted data blocks, and decrypts encrypted data blocks and unencrypted data blocks The original data information to be transmitted is obtained by performing adaptive recombination, and the system includes modules corresponding to the steps of the method.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a method and system for secure data transmission combining multi-mode communication and Aont transformation. Background technique [0002] At present, the existing multi-mode communication technology is to select a communication link with the best quality (such as SDN) to transmit ciphertext data when there are multiple communication links between the communicating parties, so as to achieve the goal of the highest efficiency. Aont Transform (All-or-Nothing Transform) is to map and transform the plaintext first, then encrypt some data blocks, and use the ratio of encrypted data blocks to the overall plaintext data blocks to improve the efficiency of data transmission and minimize The security of the data itself. [0003] There are following problems in prior art: [0004] 1. Although SDN uses link optimization to improve data transmission efficiency, the encryption pro...

Problems solved by technology

[0004] 1. Although SDN uses link optimization to improve data transmission efficiency, the encryption process (full data encryption) in the early stage of data transmission takes a lot of time, and it also increases the burden of data decryption on the receiver. Transmission on the same link reduces data security (because the eavesdropper has good enough conditions to receive a piece of continuous or even all ciphertext data);

[0005] 2. Although the Aont transformation improves the transmission efficiency and claims that the security of the data itself should not be reduced as much as possible, in fact, because the Aont itself is not encrypted, it is just a transformation. Compared with encrypting all data after transformation, encryption of some data is more secure. defective
