Cipher character string generation method and apparatus

Abstract

The invention provides a cipher character string generation method. The method comprises the following steps: prestoring multiple encryption algorithms; acquiring data to be encrypted in a data set S of cipher character strings to be generated; and by use of the encryption algorithms, performing encryption operation on the data to be encrypted so as to generate the cipher character strings. According to the embodiments of the invention, the cipher character strings are generated through arrangement of the multiple encryption algorithms, and the method and apparatus have the positive effects of reducing the risk of cracking the cipher character strings and improving the security of the cipher character string.

Description

technical field [0001] The present invention relates to the technical field of password generation methods, in particular to a method and device for generating password strings. Background technique [0002] At present, with the popularity of touch screen technology on smart terminal devices, mobile payment methods are becoming more and more popular in the process of commodity transactions. When using mobile payment methods for payment activities, traders often need to enter passwords or verify code; for example, when people use Alipay, WeChat and other payment methods to pay, and open the relevant function to pay the corresponding payment, they will get a password string, which is crucial to the security of the entire payment activity as a security verification code. role. [0003] However, the existing methods for generating password strings have problems such as using a single password string generation algorithm to generate password strings, fixed and simple password st...

AI Technical Summary

Problems solved by technology

[0003] However, the existing methods for generating password strings have problems such as using a single password string generation algorithm to generate password strings, fixed and simple password string generation rules, and high probability of repetition of generated password strings, which lead to the generation of password strings. The password string is easy to guess and crack, which will eventually threaten the security of payment activities and the safety of people's property
