Problems solved by technology

[0028] However, security-wise this system is heavily affected by attack methods developed by Bricke, Lagarias and Odlyzko, Schnor et al.
That is, the recipient's private key is easily discovered by a third party, so that the problem of easy leakage of information data occurs

Embodiment Construction

[0036] The present invention will be described in detail below with reference to the accompanying drawings.

[0037] FIG. 1 is a flow chart of the process of generating a public key and a private key according to an embodiment of the present invention.

[0038] The process first generates a private key (cc t , W 1 , W 2 , M), where cc t means n K 1 × K 1 Sequence of superincreasing matrices, W is a k 1 ×k 1 Matrix, W 2 is a k 2 ×k 2 matrices, which are values ​​corresponding to B, W, and M', respectively, in a knapsack public-key transmission system based on superincreasing integer sequences.

[0039] First, the positive integer k 2 , k 2 , l 1 , l 2 ,..., l u is chosen arbitrarily, k 1 ×k 2 ≥3, 2≤u≤k 1 ×k 2 -1, which is represented as (step 110).

[0040] Then, select relative to each s (1≤s≤u), with length l s , a sequence of n superincreasing integers, which is denoted as d s =(d s，1 , d s，2 ,...,d s，1 ), 1≤s≤u (step 120). This superincreasing in...

Abstract

The present invention relates to a method for transmitting binary information through electronic transmission media, which comprises a step of producing a public key and a private key as a preparatory stage for encrypting binary information data, a step of encrypting binary information by using the public key, and a deciphering step wherein super-increasing matrix sequences are used in producing the public key and the private key for encryption.

Description

technical field [0001] The present invention relates to a method of transmitting binary information through an electronic transmission medium; in particular, to a method of encrypting and decrypting binary information during transmission using a sequence of super-incrementing matrices. Background technique [0002] Recently, in the case of the transmission of information via electronic transmission media, especially in the transmission of data between computers, the issue of confidentiality has been increasingly emphasized. In fact, data transmitted over transmission lines is relatively easy to eavesdrop, which means that important information can be transmitted to third parties. In order to prevent such danger, it is necessary to encrypt the transmitted information so that it cannot be easily understood by a third party. [0003] In order to encrypt information, various encryption methods have been proposed. These encryption methods are broadly classified into: symmetric ...
