Computer permission control method based on mobile dynamic password

Abstract

The invention relates to a computer permission control method based on a mobile dynamic password. The computer permission control method based on the mobile dynamic password comprises the following steps: generating a private key and a public key by adopting encryption algorithm at an personal computer (PC) end and sending the public key to a mobile end; encrypting a PC management password, using time and permission level information which are stored at the mobile end in advance by adopting the public key after the mobile end receives the public key, generating a ciphertext string, and then sending the ciphertext string to the PC end; deciphering the ciphertext string by adopting the private key after the PC end receives the ciphertext string, getting the PC management password, the using time and the permission level information; and conducting a password authentication with the PC end by using the PC management password information. When the PC end passes the password authentication, computer permission is opened according to the using time and the permission level information. When the PC end does not pass the password authentication, the computer permission ends. Compared with the prior art, the computer permission control method based on the mobile dynamic password has the advantages of being capable of achieving a remote control of the using time and the permission of a computer by a mobile, convenient to use, good in safety and the like.

Description

technical field [0001] The invention relates to an information processing method, in particular to a computer use authority control method based on a mobile phone dynamic password. Background technique [0002] With the application of computers more and more widely, modern society has gradually entered the information age. Huge amounts of data are input and output from computers every day. Therefore, the security of the data has been transferred to the security protection of the computer accordingly. Therefore, the access protection of personal PC or Notebook is very important. We generally set a login password at startup to ensure that only those who know the password have access to the computer. [0003] However, many times, we often encounter such a dilemma: when we are away from home, friends or colleagues suddenly need to use our computer for urgent matters, and they call us to ask us for the unlocking password of the computer. However, this password is our common p...

Problems solved by technology

[0004] The traditional remote dynamic password system uses a dynamic password generated from a time seed. This approach has two major drawbacks: First, if the dynamic password generation algorithm is public, anyone can derive the dynamic password from time, and the system security is low.

Secondly, there is no guarantee that the time synchronization between the mobile phone and the PC will be maintained. If the time is not synchronized, the password will become invalid.
