Abstract

The invention provides a user request permission method and device based on password confusion. The method can be used in the technical field of finance. In a reasonable salting processing mode, confusion is carried out in combination with a hash function, so that the method has the characteristics of counterfeiting resistance, eavesdropping resistance, replay attack resistance, dictionary attack resistance after database leakage, incapability of acquiring a password plaintext in the whole process, infeasibility of violent exhaustion and reverse cracking of the password plaintext in cost calculation and the like, and the safety of a user logging in an account through a webpage is ensured to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of Internet finance, in particular to a password obfuscation-based user request permission method and device. Background technique [0002] The webpage-based user login authentication system uses cryptography and network security related technologies to obfuscate and hash sensitive information such as user passwords transmitted through the network and in background processing when users register and log in to their accounts. Persistent storage is carried out in the database to ensure that user passwords pass system authentication without being leaked, cracked, or tampered with. However, in practical applications, there will be more or less various loopholes, such as hashing passwords without adding salt, using hash functions that have been found to have collisions, and transmitting plaintext passwords to background processing, etc., which will cause varying degrees of vulnerability. risk, reducing the secur...
