Abstract
The present invention relates to electronic communication technology security fields more particularly to a kind of data ciphering methods, it is therefore intended that the deficiency for solving available data encryption technology provides a kind of data ciphering method, and the encryption intensity of the data ciphering method is high, is not easy to crack.The present invention is that data information to be encrypted is changed into number, selects suitable one group of relatively prime two-by-two number to its complementation, new number is formed with these remainders, these numbers can continue to encrypt in this way, it is also possible to these number composition ciphertexts (Fig. 1).Each remainder and the used corresponding cipher key calculation of number of encryption go out former number before encrypting in ciphertext when decryption, and reconvert is at original data information.The data information encryption that all can be exchanged into number present invention is mainly applied to all kinds of words, figure, table, audio, video and photoelectricity signal etc., the encryption of Various types of data information suitable for the network of light, electronic equipment and its composition or the network platform, it is ensured that related data safety.
Description
【Technical field】The present invention relates to light, telecom technology security fields more particularly to a kind of data ciphering methods.
【Background technology】Today's society is an information highly developed epoch, and various information is widely stored in electricity
In the various light such as brain, mobile phone, electronic equipment and network cloud storage.Many important information for example personal identification number, cell-phone number,
After the individual privacy informations such as bank's card number are leaked or are stolen, prodigious puzzlement can be caused to individual, or even is caused serious
Property loss, enterprise's unique technology, technical recipe, technological process can cause enterprise's heavy losses after being leaked or being stolen
It even goes bankrupt, mechanism of governments at all levels is that the data for improving working efficiency and being stored in the various network platforms extensively then increase correlation
The danger of information leakage.Therefore, it is necessary to which storage is encrypted to Various types of data information, to accomplish to have stolen these letters even if others
Breath, can not also use.
Current enciphering and deciphering algorithm, such as triple data encryption algorithm (3DES) and Advanced Encryption Standard (AES) etc., due to
The present computer speed of service is getting faster, the development of also various distributed type assemblies technologies, the possibility of Brute Force password
Property it is increasing, so the simple reliability using 3DES the and AES scheduling algorithms having disclosed can have a greatly reduced quality.Therefore, compel
Be essential to provide a kind of high security, high reliability encipher-decipher method.
【Invention content】It is an object of the invention to solve the deficiency of available data encryption technology, a kind of data encryption is provided
The encryption intensity of method, the data ciphering method is high, is not easy to crack.
The technical solution adopted in the present invention includes the following steps：
Encryption：
1. data information is changed into digital X：
2. select suitable one group of number { A1, A2, A3 ... Am } relatively prime two-by-two to distinguish complementation to the digital X that transformation obtains,
The digital X1, i.e. a1a2a3 ... am of remainder group { a1, a2, a3 ... the am } composition obtained with complementation newly；
3. suitable second group of number { B1, B2, B3 ... Bm } relatively prime two-by-two is selected to distinguish complementation to digital X1, obtained with complementation
The digital X2, i.e. b1b2b3 ... bm of remainder group { b1, b2, b3 ... the bm } composition arrived newly；
……
4. ... array { N1, N2, N3 ... the Nm } complementation respectively that the finally selectes is substituted into using MOD functions, is obtained with complementation
Digital Xn, the i.e. n1n2n3 ... nm of remainder group { n1, n2, n3 ... the nm } composition arrived newly, replace former data information to become close with Xn
Text.
Decryption：
1. utilizing the array { N1, N2, N3 ... Nm } corresponding decruption key { 1n, 2n, the 3n ... that encrypt selection for the last time
Mn } former number is sought, find out number before encrypting；
2. carrying out asking former number operation ... successively from back to front；
3. with most starting to encrypt array { A1, A2, A3 ... Am } corresponding decruption key { 1a, 2a, the 3a ... of selection for the first time
Ma } former number is sought, find out number X before encrypting；
4. digital X is converted to former data information.
Compared with prior art, the beneficial effects of the invention are as follows total data information is encrypted, when encryption, only retains
Modulus operation result, rule difficulty are sought, other people be difficult to find that correctly encryption, decryption array, it is ensured that data not because other people illegally into
Enter and divulges a secret；Encrypting and decrypting calculating is simple and fast, and encrypting and decrypting work can be rapidly completed in data information user.
【Description of the drawings】Fig. 1 is the flow chart of data ciphering method according to the ... of the embodiment of the present invention, and Fig. 2 is according to the present invention
The flow chart of the data decryption method of embodiment.
【Specific implementation mode】Hereafter provided to one embodiment of the invention with together with the attached drawing of the diagram principle of the invention
Detailed description.The present invention is described in conjunction with such embodiment, but the present invention is not limited to any embodiments.The scope of the present invention is only
It is defined by the claims, and the present invention covers many replacements, modification and equivalent, illustrates in the following description many specific
Details is in order to provide thorough understanding of the present invention.These details are provided for exemplary purposes, and without in these details
Some or all details can also realize the present invention according to claims.
Data information example " reading aloud " is implemented to encrypt
1. data information " reading aloud " is changed into digital " 41534112 "；
2. with first group selected, mutual prime rwmber { 719,929,997 } distinguishes complementation to number 41534112 two-by-two, obtains remaining
Array { 358,380,89 } forms new number 358380089 with remainder：
3. with second group selected, mutual prime rwmber { 41,59,89,91,97 } distinguishes complementation to number 358380089 two-by-two, obtains
To remainder group { 32,47,51,67,9 }, new number 3247516709 is formed with remainder；
4. by number 3247516709 as data information " reading aloud " encrypted ciphertext, encrypted work is completed, it also can be after
Continuous selection array appropriate is encrypted, and regard final number as ciphertext.
