Embodiment 1

[0028] When the electronic signature device is processing ordinary commands, after the upper computer sends an instruction, the upper computer waits until the electronic signature device returns the response data to the upper computer; if the upper computer thread does not receive the device response data for a long time, the upper computer Threads may also be timed out. The inventor of the present application considers that, using the above-mentioned ordinary command processing method, the timeout period of the host computer thread will be set relatively long, and the host computer may cause thread blockage during the long-term waiting for the response. In addition, the electronic signature device also Instruction blocking may occur. Moreover, when the upper computer does not receive a response for a long time at this time, it is not known whether the electronic signature device has a problem, or the electronic signature device is normally waiting for the user to confirm.

Embodiment 2

[0037] This embodiment provides an electronic signature device that can implement the method in Embodiment 1 above, and the device at least includes the following units.

[0038] The receiving unit receives the instruction that needs to be confirmed issued by the host computer;

[0039] Wherein, the above-mentioned receiving unit may also receive other instructions issued by the upper computer and / or operation instructions initiated by the user after the sending unit sends a response to the instruction to the upper computer.

[0040] The sending unit is configured to send a response to the command to the host computer after the receiving unit receives the command from the host computer that needs to be confirmed, and the response indicates that the electronic signature device is in a state of waiting for user confirmation.

[0041] The above-mentioned sending unit also feeds back the current state of the electronic signature device to the host computer when the receiving unit ...

Abstract

The invention discloses electronic signature equipment and a command processing method thereof, and relates to the field of information safety. The command processing method of the electronic signature equipment comprises the following steps: a command, which needs to be confirmed, is transmitted to the electronic signature equipment by an upper computer, the command, which needs to be confirmed and is transmitted by the upper computer, is received by the electronic signature equipment, a response of the command is transmitted to the upper computer in a real-time manner, and the response indicates that the electronic signature equipment is in a user confirmation waiting state. The invention further discloses the electronic signature equipment. The technical scheme of the invention solves the problem of capability of avoiding the long-time waiting response of a thread of the upper computer when the electronic signature equipment executes the command, of which the function needs to be confirmed.

Description

technical field [0001] The invention relates to the field of information security, in particular to an electronic signature device and an instruction processing method thereof. Background technique [0002] In order to solve the security problem of online banking, an electronic signature device without confirmation function (also known as a smart password key) has appeared. This device is protected by a password, and a digital certificate is stored in the device for electronic signature. No need to display and confirm. Later, an electronic signature device (smart password key) with a confirmation function appeared. This device is protected by a password and stores a digital certificate inside. User confirmation is required for operations such as transaction signature, verification of PIN, and modification of PIN. [0003] All electronic signature devices need to communicate with the host computer, and the two interact through instructions and responses. The upper computer ...
