How to deal with scattered information

Abstract

The present invention provides a processing method for information dispersal, which includes: determining the processing node where the information is dispersed; the distribution node performs information block processing on the information to be processed; The number of bits is determined by random selection; the obtained information blocks are respectively transmitted to the corresponding processing nodes, and processed by the processing nodes. The information dispersal processing method of the present invention provides a more changeable processing method for the realization of information dispersal. The scheme uses random selection of irreducible polynomial digits and irreducible polynomial types to disperse information, making the processing process more complex and diverse. Changes, increase the difficulty of analysis for attackers, and improve the security of information dispersion.

Description

technical field [0001] The invention relates to the technical field of information dispersion processing, in particular to an information dispersion processing method. Background technique [0002] Existing information decentralized processing methods generally use Shamir encryption sharing technology to disperse information processing. This method generally transforms data through a fixed linear equation system, and Shamir encryption sharing is as follows: [0003] If for n sharing nodes {U 1 , U 2 ,...,U n}, the threshold value is t, encryption is s, p is a large prime number, X 1 , X 2 ,...,X n In order to correspond to the identity information of the sharing node (processing node), except for the encrypted s, other parameter information is disclosed; when encrypting and distributing, the encrypted distribution node D randomly selects a polynomial f(x) of degree t-1 on GF(p) = a 0 +a 1 x+a 2 x 2 +…+a t-1 x t- 1 modp,a i ∈GF(p), satisfy the requirement f(0)=a...

Problems solved by technology

[0009] (2) In the case of less than t, the encryption cannot be obtained

[0010] However, when the currently used information is distributed using a fixed set of linear equations for calculation, the information processing method is single, the irreducible polynomial is fixed, and the number of binary fields is fixed, which makes it vulnerable to attacks
