Embodiment 1

[0090] In this embodiment, the server and the information security device are preset with the same generation elements. Referring to FIG. 1, the embodiment of the present invention provides a remote unlocking method, which specifically includes the following steps:

[0091] Step 101: the user provides authentication information to the server.

[0092] When purchasing information security equipment, users are required to provide their own valid certificates, which will be stored in the server as authentication information for later unlocking. For example, if users provide their own ID cards when purchasing information security equipment, then Its ID number will be stored in the server.

[0093] The authentication information provided by the user may also include the hardware identifier of the information security device. After receiving the authentication information, the server can find the random password algorithm corresponding to the information security device according to...

Embodiment 2

[0124] Referring to FIG. 2 , an embodiment of the present invention provides a remote unlocking system, including an information security device 200, a client 300 and a server 400,

[0125] The information security device 200 includes a generation module 201, a communication module 202, a comparison module 203 and a control module 204:

[0126] The generating module 201 is used to generate an identification code according to a preset random password algorithm under the control of the control module 204, and send the identification code to the comparison module 203;

[0127] The communication module 202 is used to receive the identification code input by the user through the client terminal 300 under the control of the control module 204, and send the received identification code to the comparison module 203;

[0128] The comparison module 203 is used to compare whether the identification code sent by the communication module 202 is consistent with the identification code sent ...

Abstract

This invention discloses a remote unlocking method and a system, in which, the method includes: an information safety device generates an identification code according to a preset random password algorithm and receives a heading code of a user input by a user terminal, which is one that after a service end verifies the user is a legal one according to the authentication information provided by the user, it applies a same method to generate the identification code by the information safety device and returns it to the user, the identification code and the heading code are compared, if they are consistent, then the user is allowed to enter into the operation system in the device to alter its state, otherwise, the user is forbidden to enter into the operation system to alter the state of the device. The system includes: an information safety device, a client end and a service end.

Description

technical field [0001] The invention relates to the field of information security, in particular to a remote unlocking method and system. Background technique [0002] With the development of computer technology, people pay more and more attention to information security. In recent years, information security equipment is a small hardware device with processor and memory, which can be connected to the computer through the data communication interface of the computer. It is connected to the computer through the USB (Universal Serial Bus, Universal Serial Bus) interface, which is usually called USB KEY or USB Token (identity authentication device). In addition, the information security device can also use the ISO14443 communication interface, that is, the non-contact communication interface , the interface is a contactless smart card communication standard formulated by ISO (International Standardize Organization, International Organization for Standardization). Information s...
