Problems solved by technology

[0005] The asymmetric algorithm mainly uses the public key (publickey) and (privatekey) private key algorithm, that is, the public key is encrypted, the private key is decrypted, and the private key is encrypted, the public key is decrypted. The public key and the private key are in one-to-one correspondence and only use First, the asymmetric algorithm is theoretically more secure than the MD5 algorithm, but the decryption of the asymmetric algorithm is time-consuming. Compared with the similar MD5 algorithm, the asymmetric algorithm is even 1000 times slower than the MD5 algorithm, and the IC card or U- The key itself is a microcomputer system. For example, the PBOC card issued in China has its own

specific Embodiment approach

[0010] Specific implementation methods: The implementation methods discussed in this specification introduce the general process of implementing this patent, but implementing this patent does not necessarily need to completely follow the process described here, it is only a special case of implementing this patent.

[0011] Explanation of terms: source data, strictly speaking, connection variables, passwords entered by users, etc. are also source data, but the source data in this manual is defined in a narrow sense, which only refers to encrypted data, such as 6 groups of connection variables through magnetic stripe cards The imported 6 sets of data, these 6 sets of data are the source data, and the others are not source data. For encryption needs, the source data has more characters, too few characters, and the encryption strength is not enough.

[0012] Data and characters, strings, in computer and telecommunications technology, a character is the basic information of a unit ...

Abstract

A digital encryption algorithm uses a connection variable to connect a same kind field or a same kind data table and performs encryption on source data; the encryption method needs hardware data to participate and enables a password to be complex through multiple times of encryption and expanding encrypted data; and the biggest characteristic of the password is that the encrypted data is not completely stored, so that cracking on the server terminal is very difficult.

Description

technical field [0001] The invention belongs to digital encryption technology. Background technique [0002] The following first introduces the general situation of commonly used digital encryption algorithms: [0003] What we often call passwords are actually passwords. Passwords can be understood as a very difficult translation. It translates recognizable text into unrecognizable text. Passwords and digital certificates are special passwords. The telegram message used is the real password. It converts Chinese into a four-digit number. The long and short signals of each number are different. Use these long and short signals to send and receive. After receiving, find the corresponding Chinese through the number. , through manual translation into the original text, the digital number of the mass telegram is not a secret, so the encryption performance of the mass telegram message is very poor. In addition to the telegram message, there is also a password transmitter. The prin...
