Problems solved by technology

The administrator needs to enter the PIN code of the administrator through the computer. After the computer receives the PIN code of the administrator, it sends it to the smart key device, and then the smart key device verifies the received administrator PIN code. After the verification is successful, the management Then the staff enters the new PIN code and confirms the PIN code through the computer, and the computer sends the received PIN code and the confirmed PIN code to the smart key device. The administrator PIN code, new PIN code and confirmation PIN code entered by the administrator; further, when the computer receives the above PIN code through the network, illegal users also have the opportunity to intercept the PIN code through the network

Embodiment 1

[0083] Embodiment 1 of the present invention provides a method for unlocking a PIN code. It should be noted that the smart key device provided in Embodiment 1 of the present invention stores the original PIN code and private key internally, and is provided with an input device and an output device externally. , the input device is a keyboard, and the output device is a monitor. In this embodiment, a typical smart key device such as USB Key is used as the execution subject of the method for illustration, but it is not intended to limit the execution subject of the method. within the scope of protection.

[0084] In Embodiment 1, in order to separate the buffer for storing the administrator PIN code input by the user, the buffer for storing the new PIN code input by the user, and the buffer for storing the confirmation PIN code input by the user, therefore, the buffer for storing the user input The buffer for the administrator PIN code is called the first buffer, the buffer for...

Embodiment 2

[0188] Embodiment 2 of the present invention provides a smart key device, see figure 2 , the smart key device includes:

[0189] A connection module 201, configured to establish a connection with a computer;

[0190] Preservation module 202, is used for preserving administrator's PIN code and private key;

[0191] The receiving module 203 is used to receive the instruction and user input of unlocking the PIN code sent by the computer;

[0192] The setting module 204 is used to clear the buffer zone, and the current state is set to the state of waiting to input the administrator PIN code;

[0193] Judging module 205, configured to judge the current state of the smart key device;

[0194] An input module 206, configured to implement user input;

[0195] The administrator's PIN code module 207 is used to store the number represented by the digital key signal input by the user through the smart key device input module 206 into the first buffer when the judging module 205 judg...

Abstract

The invention discloses a method for unlocking a PIN code and an intelligent secret key device, relating to the information security field. The method is as follows: the intelligent secret key device is connected with a computer and receives commands of the unlocking PIN code sent by the computer; the intelligent secret key device empties a buffer zone and sets the current state to be awaiting input administrator PIN code state; the intelligent secret key device receives the user input and judges the current state; according to the current state, follow-up steps are implemented; and the intelligent secret key device comprises a connecting mode, a storage module, a receiving module, a set module, a judgment module, an input module, an administer PIN code module, a new PIN code module, an identification PIN code module, an output module, a sending module, a permission management module and an intelligent secret key module.

Description

technical field [0001] The invention relates to the field of information security, in particular to a method for unlocking a PIN code and an intelligent key device. Background technique [0002] The smart key device is a small hardware device with a processor and a memory, which can be connected to a computer through the computer's data communication interface. The smart key device completes the key generation and safe storage of the key through the built-in single-chip microcomputer or smart card chip. The encryption algorithm function can be preset, and the operation related to the key is completely run inside the smart key device, so that the smart key The key device has the characteristics of anti-attack and high security. [0003] In the prior art, the smart key device generally verifies whether the user's identity is legal by verifying whether the PIN (personal identification number, personal identification number) code input by the user is correct or not. The specif...
