Embodiment Construction

[0062] In order to better understand the technical solution of the present invention, the present invention will be further described below in conjunction with the accompanying drawings.

[0063] Fundamental

[0064]The idea of ​​network coding technology was first clearly proposed by R.W.Yeung and Z.Zhang in 1999. Its idea is to change the routing function that nodes in the traditional network can only perform single storage-forwarding of received information, so that it can The information from different links is processed, which not only realizes the traditional routing storage-forwarding function, but also realizes the encryption processing of information, thereby improving the transmission capacity and reliability, and finally still enables the destination node to successfully receive the required information. information. In 2000, Rudolf Ahlswede, Cai Ning, Li Shuoyan and Yang Weihao made a far-reaching discussion on the theoretical significance and application value of...

Abstract

The invention provides a method for improving information transmission security. The method comprises the steps that 1 according to locations, calculation is conducted on a to-be-encrypted file and an encrypted sample file with the same length, and an intermediate file is obtained; 2 the intermediate file is evenly divided into N segments, and the N segments are sorted randomly; 3 a mutual iterative calculation is conducted on the N segments, and cryptographs are obtained; 4 the cryptographs are graded according to secret grades, encryption grade information is stored in the cryptographs, and a final cryptograph is obtained; 5 decoding is conducted on the final cryptograph; 6 a cracking protection program is started, when the decoding times exceed a predetermined value, automatic destruction is conducted on the final cryptograph, and an operating system is closed. The method can break the limitation and constraint of 'an algorithm +a secret key', the file secret mode completely depending on 'the secret key' is changed, 'personality encryption' of each file is achieved, and the effect of one-time padding is achieved.

Description

technical field [0001] The invention relates to the field of secure communication, in particular to a method for improving the security of information transmission. Background technique [0002] Since the "Stuxnet" virus attack on the Iranian nuclear facility test base in September 2010, the "Duqu" virus and the "Flame" virus have been discovered in Europe, the Middle East, and Hong Kong. These viruses are extremely concealed, extremely complex, and extremely destructive, which fully demonstrates that the information war in cyberspace has risen from individual behavior to national organization, from independent incidents to chain attacks, and the attack methods are becoming more and more complex. The higher the level, the greater the impact of damage. Conventional security technologies and methods are often broken shortly after they are implemented and applied. [0003] Modern information encryption technology adopts the basic idea of ​​"algorithm + key". In the specific e...
