Problems solved by technology

[0004] In the prior art, the dongle allows the user to execute any command in the dongle as long as it receives the user's verification PIN information. There is no restriction on the commands in the dongle, so the security is low, and when the user needs to know When encrypting the lock information, the existing encryption lock cannot be displayed to the user intuitively, and the user experience is poor

Embodiment 1

[0174] Embodiment 1 of the present invention provides a working method of a multifunctional encryption lock, such as figure 1 , figure 2 and image 3 shown, including:

[0175] In this embodiment, a preset security policy is set in the dongle in advance, wherein the preset security policy includes: after receiving the instruction, obtaining the conditions for executing the instruction from the preset security policy, including the expiration date and security authority, for example , when executing the read data operation instruction, data encryption instruction, data decryption instruction, executing the encryption lock program instruction and display instruction, determine whether the service period in the preset security policy has expired; When authorizing the information instruction and setting the display page instruction, determine the usage period in the preset security policy and determine the security authority in the preset security policy;

[0176] The working ...

Embodiment 2

[0373] The second embodiment of the present invention provides a multifunctional encryption lock, such as Image 6 As shown, it includes: a receiving module 101, a judging module 102, an obtaining module 103, a setting module 104, a display module 105, an updating module 106, a processing module 107 and a sending module 108, and the work between the modules is as follows:

[0374] Receiving module 101: used for receiving the instruction sent by the upper computer;

[0375] Judging module 102: used to judge the type of the instruction when the receiving module 101 receives the instruction sent by the host computer; when judging that the instruction type is the PIN verification instruction, determine whether the PIN code in the PIN verification instruction is correct; when When acquiring the preset security policy, the acquiring module 103 determines whether the data output instruction, the setting display page instruction and the display instruction are executable according to ...

Abstract

The invention discloses a multifunctional encryption lock and an operating method thereof, and belongs to the field of information safety. The method comprises the steps: electrifying the encryption lock, setting security permission to be an initial value, displaying preset information, receiving a PIN inspection instruction, a data output instruction, a display page setting instruction and a display instruction by the encryption lock, judging whether the instructions can be executed or not according to preset security policies, receiving display policies in the display page setting instruction by the encryption lock, and displaying according to the display policies during instruction displaying. According to a technical method, the security policies are preset by the encryption lock, and whether the received instructions can be executed or not is judged according to the preset security policies, so the safety of using the encryption lock is increased; in addition, by the technical scheme, different display policies can be set according to user needs, internal information needing to be visually displayed is displayed by the encryption lock according to the display policies, and the user experience is good.

Description

technical field [0001] The invention relates to the field of information security, in particular to a multifunctional encryption lock and a working method thereof. Background technique [0002] The encryption lock is an intelligent tool with software protection function provided for software developers. It includes a hardware installed on the parallel port or USB port of the computer, and a set of interface software and tool software suitable for various languages. [0003] The encryption lock is based on hardware protection technology, and its purpose is to prevent the illegal use of intellectual property rights through the protection of software and data. Therefore, software developers can set multiple software locks in the software, and use dongles as keys to open these locks. If no dongle is inserted or the dongle does not correspond, the software will not run normally. [0004] In the prior art, the dongle allows the user to execute any command in the dongle as long as...
