Embodiment Construction

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0030] Following figure 1 Take an example to describe the specific process of embedding information in the text of the document according to the present invention;

[0031] The particle-based nonlinear encryption method is composed of five parts: the encrypted information format conversion module, the information segmentation module processing module, the parameter coordinate conversion module, the nonlinear encryption module, and the encrypted information output module. The specific flow chart of the information encryption is described as follows:

[0032] Before the information is encrypted, first, in step S1, the encrypted information format conversion unit automatically reads the encrypted information, and automatically converts the encrypted information in any format into a binary format. Binary format is a general format for computer storage ...

Abstract

The invention relates to a method for carrying out chaotic encryption based on particle travelling, comprising the following steps of: (1) initializing: randomly generating or setting initial parameters according to given information, wherein the initial parameters comprise a reflection container parameter, an initial position, a running speed, running time and a running direction; and (2) computing a track by iteration based on the initial parameters and a reflection law to obtain the final collision position and direction and realize the encryption of the data. The method provided by the invention has the advantages of simplicity in operation, sensitivity on the initial parameters and unilateral directivity of a chaotic encryption algorithm, so that the method can be widely applied to information safety of encrypted data, secret communication and the like.

Description

Technical field [0001] The invention involves the field of encryption technology, and specially involves the use of key control for data encryption and decryption related technologies. Background technique [0002] In the modern electronics era, the data processing date that is exchanged on the public telecommunications channel [0003] Common business, official affairs and private affairs are increasing day by day.The latest statistics show that the number of global netizens has exceeded 1 billion, and the Internet penetration rate of the Internet in the EU, the United States, South Korea, Japan and other countries has basically exceeded 50%, up to 68.6%.Compared with traditional information, digital information has many advantages such as low cost, easy organization and processing, convenient preservation, long validity period, and easy communication.Although digital information has many advantages than traditional information, fundamentally, it is only another new type of expr...
