Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
Fig. 1 is a schematic flowchart of a key security device interaction method, which is used for a terminal device, such as a mobile phone, a tablet, a dedicated read-write device, and the like, that can establish bluetooth communication with a key security device.
The key security device interaction method comprises the following steps:
step S110, when the terminal equipment is in an idle state, first data are obtained from the key safety equipment; the first data includes at least one data block.
In this embodiment, the first data represents data acquired by the terminal device from the key security device in the idle state, and the data acquired by the terminal device in the idle state may be preset according to actual application without limiting what type of data is; for example, larger files, such as files above 1 kbyte; the data usage can also be preset at the terminal device, for example, the acquired first data is an electronic signature file, and is generally tens of kbytes or twenty kbytes in size. When the terminal device is in an idle state, one or more first data are acquired from the key security device, and the type and the purpose of each first data may be the same or different.
The terminal equipment is provided with a program interacting with the key safety equipment, and actively generates or executes an instruction interacting with the key safety equipment or through the operation of a user, namely when the instruction is operated, the terminal equipment is in a working state; the terminal device is in an idle state when the terminal device does not generate or execute instructions to interact with the key security device.
When the terminal equipment is in an idle state, first data is obtained from the key safety equipment so as to prepare for subsequent operation instructions to use a data block in the first data. Therefore, when the operation instruction needs to use the data block in the first data, the data block in the first data acquired from the key security device by the terminal device in the idle state can be directly utilized, and the data does not need to be read from the key security device in a low-speed Bluetooth communication mode, so that the execution time of the operation instruction and the waiting time of a user are reduced, and the interactive experience of the user in the process of using the key security device is improved.
When the operation instruction needs to use the data block in the first data, the data block in one or more first data acquired by the terminal device from the key security device in the idle state can be directly utilized, and the type and the purpose of the data block in the acquired first data can be the same or different. For example, although the terminal device acquires a plurality of data blocks from the key security device in step S110, an operation instruction at a certain point of time only needs to use one data block in the first data acquired from the key security device while the terminal device is in the idle state.
As a preferred embodiment, the terminal device is provided with a program for interacting with the key security device, the program comprising a driver layer for establishing a connection with the key security device, and an application layer for processing specific instructions. In step S110, first data is obtained from the key security device, specifically, the driver layer obtains the first data from the key security device.
As a preferred implementation, after the terminal device is connected with the key security device by bluetooth, the current state is initialized to an idle state; the first data is then obtained from the key security device.
After the terminal device is connected with the key security device, some data blocks are read from the key security device and the read data blocks are cached as the acquired first data.
As a preferred implementation, after the terminal device is connected with the key security device by bluetooth, the current state is initialized to an idle state; the first data is then retrieved from the key security device before the operation instruction is not retrieved.
And step S120, if the operation instruction is acquired, the operation state is changed to the working state.
The terminal device actively or through the operation of the user generates or executes the instruction interacting with the key security device, namely, when the operation instruction is generated, the terminal device is converted into a working state.
When the operation instruction is acquired, the appropriate time can be waited to convert the operation instruction into a working state after acquiring a section of complete data from the key security equipment; and the data acquisition from the key security equipment can be stopped in an interruption mode, and the key security equipment is instantly switched to a working state.
Step S130, if the first data includes the data block required by the operation instruction, executing the operation instruction according to the corresponding data block in the first data.
For example, when the terminal device is in an idle state, the first data acquired from the key security device includes a complete electronic signature file, and data required by an operation instruction is also the electronic signature file, so that the terminal device can execute the operation instruction according to the electronic signature file in the first data, such as performing an operation of identity authentication and the like.
In a preferred embodiment, the operation instruction includes a read data command, for example, an operation instruction includes a command for reading data of an electronic signature file.
As a preferred embodiment, the terminal device is provided with a program for interacting with the key security device, the program comprising a driver layer for establishing a connection with the key security device, and an application layer for processing specific instructions.
As a preferred implementation manner, step S130 executes the operation instruction according to the corresponding data block in the first data, specifically, the application layer executes the operation instruction according to the corresponding data block in the first data.
According to the key security equipment interaction method provided by the embodiment of the invention, the first data is obtained from the key security equipment in advance in the idle state, so that the data block in the first data is used by a subsequent operation instruction; therefore, when the operation instruction needs to use the first data, the first data acquired from the key security device when the terminal device is in the idle state can be directly utilized, and the data does not need to be read from the key security device in a low-speed Bluetooth communication mode, so that the execution time of the operation instruction and the waiting time of a user are reduced, and the interactive experience of the user in the process of using the key security device is improved.
As a preferred embodiment, the key security device interaction method further comprises the following steps:
step S140, if the data required by the operation instruction includes the second data, acquiring the second data from the key security device. The second data is data that is required by the operation instruction and is not acquired from the key security device in an idle state.
In the present embodiment, the second data represents data acquired from the key security device when the terminal device is not in the idle state. Since the terminal device has a limited time in the idle state, sometimes the first data acquired from the key security device may not include data necessary for the operation instruction.
For example, when the terminal device is in an idle state, the first data acquired from the key security device does not include an electronic signature file, that is, the second data, and the data required by a certain operation instruction is the electronic signature file; therefore, the terminal device still needs to obtain the required data, i.e. the second data, such as the electronic signature file, from the key security device at this time. For another example, when the terminal device is in an idle state, the first data acquired from the key security device only includes one part of the electronic signature file, and the other part which is not acquired is the second data; therefore, when the terminal device needs the electronic signature file according to an operation instruction, another part of the electronic signature file, namely the second data, is acquired from the key security device.
In a preferred embodiment, the operation instruction includes a read data command, for example, an operation instruction includes a command for reading data of an electronic signature file.
And step S150, executing the operation instruction according to the second data.
After the terminal device acquires the required second data from the key security device, the terminal device may execute the operation instruction, such as identity authentication, according to the second data, such as the electronic signature file.
As a preferred implementation manner, step S150 executes the operation instruction according to the second data, specifically, the application layer executes the operation instruction according to the second data.
As a preferred embodiment, the key security device interaction method further comprises the following steps:
step S160, if the data required by the operation instruction includes the corresponding data block and the second data in the first data, acquiring the second data from the key security device. The second data is data that is not obtained from the key security device in the idle state.
In the present embodiment, the second data represents data acquired from the key security device when the terminal device is not in the idle state. Since the time during which the terminal device is in the idle state is limited, sometimes the first data acquired from the key security device may not completely include data necessary for the operation instruction. For example, the first data acquired from the key security device by the terminal device in the idle state only includes the first data block, and the data required by the operation instruction includes not only the first data block but also a second data block, which is the second data. The first data block and the second data block may be different data segments in one file, or may be different files.
For example, the first data acquired by the terminal device from the key security device in the idle state includes only a first data block of an electronic signature file, and the electronic signature file includes the first data block and a second data block; the data required by an operation command is an electronic signature file, so the terminal device still needs to obtain the required data, i.e. the second data, such as the second data block of the electronic signature file, from the key security device at this time.
And step S170, executing the operation instruction according to the data block in the first data and the second data.
As a preferred embodiment, when the first data block and the second data block in the first data are different data segments in one file, the first data block and the second data block need to be merged first, that is, the first data block and the second data block are merged first, and then corresponding operation instructions are executed.
As a preferred embodiment, step S170 executes the operation instruction according to the data block and the second data in the first data, specifically, the application layer executes the operation instruction according to the data block and the second data in the first data.
Therefore, according to the key security device interaction method provided by the embodiment of the present invention, when the data acquired from the key security device does not include the data required by the operation instruction in the idle state of the terminal device, the required data is acquired from the key security device through bluetooth connection with the key security device, so that the problem of how to realize interaction with the key security device when the first data acquired from the key security device does not include the data required by the operation instruction due to the limited time of the terminal device in the idle state is solved.
Illustratively, an implementation procedure of the key security device interaction method of the present embodiment is as follows:
1. carrying out Bluetooth connection with the key safety equipment;
2. judging whether an operation command is received, if so, executing 4, otherwise, executing 3;
3. reading data from the key security device and caching the data in the memory, and executing step 2;
4. and if the operation command is judged to be a data reading command, reading uncached data from the key safety equipment according to the cached data, merging and returning, and executing step 2. For example, if the cached data block 1 and the data block 2 are read in advance, and the operation command needs to read the data block 2 and the data block 3, the data block 3 is read to the key security device and merged with the cached data block 2 and returned.
Example two
The key security device interaction method as shown in fig. 2 includes the following steps:
step S210, in an idle state, acquiring first data from the key security equipment; the first data includes at least one data block.
As a preferred implementation manner, in this embodiment, the length of the data block in the first data acquired from the key security device in the idle state is not greater than a preset length, such as 256 bytes.
Because the time that the terminal device is in the idle state is limited, the length of the data block in the first data is limited, that is, the length of the data block acquired from the key security device at one time in the idle state is not greater than the preset length. After a data block with the length not greater than a preset length is obtained, whether an operation instruction is obtained or not is inquired; therefore, the situation that the terminal device reads the first data in advance to influence the execution of the operation instruction and cause inconvenience to the use of a user is avoided.
Step S220, if the operation instruction is obtained, the operation state is changed to the working state.
Step S230, if the first data includes the data block required by the operation instruction, executing the operation instruction according to the corresponding data block in the first data.
Steps S220 and S230 correspond to S120 and S130 in the first embodiment, respectively, and are not described again.
In this embodiment, the key security device interaction method further includes the following steps:
step S240, if the operation instruction is not obtained within the preset time, obtaining a new data block from the key security device, where the new data block is a data block that is not obtained from the key security device in the idle state.
For example, the terminal device goes to an idle state within 50ms of acquiring the first data from the key security device, or the terminal device does not acquire a new operation instruction within 50ms of executing a certain operation instruction, and acquires a new data block from the key security device.
The obtained new data block may be from a different segment of the same file as the data block in the first data obtained in the previous stage, or from a different file.
The new data block represents a data block that has not been acquired from the key security device in the previous idle state, but was acquired from the key security device in the current idle state. For example, a first data block of the electronic signature file is a first data, and a second data block of the electronic signature file is a new data block.
Because the time that the terminal device is in the idle state is limited, the length of the data block in the first data is limited, namely the length of the data block acquired from the key security device at one time in the idle state is not more than the preset length; the other data block is obtained in the later idle state, so that the situation that the execution of the operation instruction is influenced when the terminal device reads the data block of the first data in advance and inconvenience is caused to the use of a user can be avoided, and the terminal device can cache more data of the key safety device for the subsequent operation instruction to use the cached data block; therefore, when the operation instruction needs to use the data, the data acquired from the key security device when the terminal device is in the idle state can be directly utilized, and the data does not need to be read from the key security device in a low-speed Bluetooth communication mode, so that the execution time of the operation instruction and the waiting time of a user are reduced, and the interactive experience of the user in the process of using the key security device is improved.
Illustratively, an implementation procedure of the key security device interaction method of the present embodiment is as follows:
1. carrying out Bluetooth connection with the key safety equipment, and initializing the current state into an idle state;
2. judging whether an operation command is received, if so, executing 5, otherwise, executing 3;
3. judging whether the current state is an idle state, if so, executing 4, otherwise, judging whether an operation command is received within 50ms, if so, executing 5, otherwise, setting the current state to be the idle state, and executing 4;
4. reading a data block from the key security device and caching the data block in a memory, wherein the data length of the read data block is 256 bytes, and executing 2;
5. and setting the current state as a working state, judging whether the operation command is a read data command, if so, reading the uncached data block from the key safety equipment according to the cached data block, otherwise, processing the operation command, and executing step 2.
