Application account login method and system based on ciphertext Hash retrieval

Abstract

The invention discloses an application account login method and system based on ciphertext Hash retrieval. The method includes the following steps: encrypting account names, passwords and other information in a mobile phone login process by using an SQLCipher technology, binding the encrypted information to a mobile phone identification code to establish an account library, and further realizing the function that the accounts and passwords are automatically classified and retrieved and automatically input during login; enabling a user to save account information in a classification mode basedon applications, encrypting the account information through a mobile phone feature code and master key related information by using an SMS4 encryption algorithm and a Hash algorithm, and then saving the information in a database to realize the double encryption of the data and database. After entering the system to turn on an application login mode, the function resides in a taskbar, when the userclicks the automatic entry function in the taskbar, the system calculates and retrieves a Hash value of a data character combination ciphertext in the background and merges the value into a characterstring, and then the corresponding account information can be retrieved by using the character string, the account login based on ciphertext Hash retrieval can be achieved, and the scheme of the invention is simple in operation and convenient in management, and has high security.

Description

technical field [0001] The invention relates to the field of applied cryptography in computer science, and more particularly, to a method and system for logging in an application program account based on ciphertext hash retrieval. Background technique [0002] Safe and proper storage of account password information plays a very important role in personal privacy protection, and password management has long been the top priority of system security. Most users like to use simple passwords or reuse the same passwords on different websites, and do not change their passwords regularly, which brings potential risks to the security of users' personal information. According to the "Cyber ​​Security Awareness Survey Report" released at the launching ceremony of the National Cyber ​​Security Publicity Week, Chinese netizens have weak cyber security awareness and lack of basic network skills. Over 70% of the respondents have the problem of using the same password for multiple accounts....

Problems solved by technology

[0005] The present invention is aimed at the password management application of the prior art. When the user inputs the password, he first needs to open the password management application to find the account password of the corresponding application, and then enter the password through short-term memory or copy and paste. The operation is complicated and difficult to manage. For the cumbersome defect, a method and system for application account login based on ciphertext hash retrieval are proposed by using SMS4 encryption algorithm and Hash algorithm
