Radix algorithm encryption method for dynamic password

Abstract

The invention discloses a basic operation encryption algorithm which is the discovery in the mathematics field and the application in the encryption field. And it is easy to be learned and spread. The invention can utilizes the variable false code (dynamic code) to solve the problem that the hacker can filch the code with the software as wooden horse. The server transmits the auxiliary code which has same number of bit with the user code to the client end, and the client utilizes the basic operation encryption algorithm to process the basic operation on the real code (stable code) and the auxiliary code, to attain the dynamic code as the false code which will be fed back to the server to be validated. Since each time the random auxiliary code is different, the dynamic code input by client is different, the invention can effectively prevent filching code. In addition, said basic operation encryption algorithm can apply the online bank, bank teller machine, POS, stock deals system, e-main system, online game, electronic business and communication.

Description

technical field

[0001] The basic operation encryption method is the invention of the discovery in the field of mathematics, the invention of the algorithm and the application in the field of encryption based on this, and belongs to the single-key block cipher system. At the same time, it can be mixed with some known stream cipher encryption methods to enhance security.

[0002] The main function of the basic operation encryption method is to protect the password! The dynamic password that can be calculated by the basic operation encryption method encrypts the static password that people are used to, which is easy to remember but easy to crack. Creatively combine the security of dynamic passwords with the ease of use of static passwords. Users only need to remember the original static password, not the dynamic password. The advanced version not only achieves one-time development on the server on the network, but also permanently and thoroughly prevents "Trojan horse" softwar...
