Abstract

The invention discloses a sequence encryption method of a complex reconstruction key. A chaotic calculation structure is constructed by using a set of composite logic, and chaotic bit field stream sequence encryption is realized. According to the method, computing logic units such as bit fetching logic, bit metabolism logic and bit reconstruction logic are scheduled through a chaos computing structure, a construction source and a control source are pseudo-randomly reconstructed section by section, and a regeneration key bit segment sequence of 'pseudo-random dislocation extraction of non-metabolized key bit segments to construct source bits or reset extraction of metabolized key bit segments to construct source bits' is constructed. The core of the method is as follows: constructing a chaos calculation structure, performing metabolism on a working pool segment by segment in an encryption process, and further extracting a bit in a construction source and a pseudo-random complex reconstruction key bit segment from a control source and a construction source carried by the working pool by segment through bit control bit fetching logic in the control source. The method has the beneficial effects that the adaptive computing capability is improved in a breakthrough manner, and a set of efficient and high-density security encryption method with a wide application space is provided.

Description

technical field [0001] The invention relates to the field of information security cryptography, and relates to a sequence encryption method for reconfiguration keys. Background technique [0002] Chinese patent application number: 201710249427.9 discloses a sequence encryption method based on a random binary sequence with an adjustable adjoint random reconstruction key. The main features of the method are: (1) using an existing random sequence to dynamically construct a seed random sequence. (2) Use the seed random sequence to pseudo-randomly construct random keys with fixed-length or variable-length bit segments. (3) The pseudo-random construction process of the random key is accompanied by the encryption process. (4) Using the transitivity of XOR operation to realize frequency-variable non-linear XOR of key to plaintext. (5) The adjustment of the key structure is realized through the adjustment of the feature quantity and other manipulation quantities and the pseudo-ran...
