Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the operations (or steps) as a sequential process, many of the operations can be performed in parallel, concurrently or simultaneously. In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1 is a schematic flowchart of a method for burning a key according to an embodiment of the present invention, where the method is applicable to burning a key, and in particular, the method is applicable to reducing the time for burning a key on a digital television board. The method can be executed by a device for burning the secret key, wherein the device can be realized by software and/or hardware and is generally integrated on a digital television board card, and in the embodiment, the digital television board card can be regarded as a printed circuit board in a digital television and can be used for controlling the operation of digital television hardware and various functional applications.
It can be understood that the key burning device can also be integrated on any terminal device, such as a computer, which needs to perform key burning. In this embodiment, taking the scenario that the method for burning the key is applied to the digital television board for key burning as an example, a person skilled in the art can determine the specific means for burning the key of other terminal devices according to the specific means adopted when the digital television board burns the key.
Before the digital television leaves a factory, an operator can burn keys corresponding to all the functional applications on the digital television board card, and the keys corresponding to all the functional applications need to be burnt to the digital television board card manually and sequentially by the operator at present, so that the time consumption is long. The invention provides a method for burning a key, which can effectively improve the time for burning the key on a production line.
As shown in fig. 1, a method for burning a key according to an embodiment of the present invention includes the following steps:
s101, burning a reference key acquired through an external interface, wherein the reference key is selected from a key set to be burned.
In this embodiment, the external interface may be understood as an external interface used for manually completing key burning in the digital television board card. Different burning means can correspond to different external interfaces, such as an operator burning a secret key through the external interfaces such as a USB or a serial port.
The reference key can be understood as a key used as a reference in the keys burned by the digital television board card at this time. And determining a key which needs to be automatically burnt in the digital television board card which is burnt at this time based on the reference key.
The key set to be burned can be understood as a set of keys required to be burned by each digital television board card to be subjected to key burning. For example, the key set to be burned may include key sets to be burned corresponding to the same batch of digital television boards, and it is not limited which digital circuit board corresponds to which key set to be burned, as long as each digital circuit board burns different key sets to be burned.
The key set to be burned can include all keys required to be burned by one digital circuit board card. Each digital television board card can have a unique key, each digital television board card can store a key set to be burned, and one key set to be burned can be selected for burning when the key of each digital television board card is burned.
The storage form of the key to be burned for each digital television board card in the key set to be burned is not limited, and only the corresponding key can be obtained when the key is burned. For example, each key may be stored in a key set to be burned in a matrix form, and the keys in different rows are keys required to be burned on different digital television boards. Each key in the key set to be burned can be stored in different addresses separately.
In the process of burning the key, the reference key obtained through the external interface can be burned firstly in the step, namely the reference key is burned through the external interface in a manual mode on a production line. Specifically, when burning the reference key, the step may be based on the specific function corresponding to the reference key, and burn the reference key into the corresponding key directory.
The method for burning the reference key acquired through the external interface is not limited, and a person skilled in the art can select a corresponding manual burning method for burning according to actual conditions. In the step, only the reference key obtained through the external interface is burnt, and the keys except the reference key do not need to be obtained and burnt through the external interface, so that the time for burning the key on a production line is reduced.
In addition, the step does not limit how to select the reference key from the key set to be burned. For example, a person skilled in the art can randomly select a key from keys required to be burned on the digital television board card as a reference key; and a key with the minimum key size in all keys required to be burned by the digital television board card can be selected as a reference key, so that the time for burning the reference key on a production line is further reduced.
After the reference key is burned, the key required to be automatically burned of the digital television board card can be determined based on the reference key so as to finish burning of the key of the digital television board card.
S102, determining a local storage path of the residual key corresponding to the reference key in the key set to be burned.
In this embodiment, the remaining key may be understood as a key, except for the reference key, of the keys that need to be burned in the digital television board at this time. The local storage path can be understood as the address of the remaining key stored in the digital television board card.
After the reference key is burned, the digital television board card can automatically burn the residual key. Specifically, in this step, a local storage path of the remaining key to be burned on the digital television board card may be determined first. The specific means for determining the local storage path of the residual key based on the reference key is not limited herein, and the specific means for determining the local storage path of the residual key based on the reference key may be determined based on the content pre-stored in the digital television board card for burning the key.
For example, the digital television board card may pre-store the key set to be burned and a key number association table formed by numbers corresponding to the keys to be burned. The key set to be burned can include all keys required to be burned by the digital television board card. The key number association table may store an association relationship between a reference key number corresponding to each digital television board card requiring key burning and a remaining key number corresponding to each digital television board card, and the key number association table may represent a storage address of each key in the digital television board.
The digital television board card may also have a key number association table and a key to be burned in the key set to be burned, except for a reference key, pre-stored therein, where the reference key may refer to a reference key corresponding to a different digital television board card in the key set to be burned.
After the reference key is burnt, a key number association table is searched based on a reference key number corresponding to the reference key, a residual key number corresponding to the reference key number is determined, and a local storage path of the corresponding residual key is determined based on the residual key number.
It can be understood that the remaining key number may include a local storage path of the corresponding remaining key, and after the remaining key number is determined, the corresponding local storage path may be directly read. The remaining key number may also be named directly with the local storage path of the remaining key. The remaining key numbers may also only serve as numbering, and the corresponding local storage path is determined based on the correspondence between the number and the corresponding local storage path.
It should be noted that the reference key burned in S101 may be predetermined or determined during burning. If the key set is determined during burning, the key set to be burned can be prestored in the digital television board card; if the reference key is predetermined, the digital television board card may pre-store the key to be burned in the key set to be burned, except the reference key, or may directly pre-store the key set to be burned.
And S103, acquiring and burning the corresponding residual key according to each local storage path.
After the local storage path of each residual key is determined, the residual keys can be directly obtained and burned in the step. Different residual keys can be stored in different addresses, corresponding residual keys are directly read based on the determined local storage path and then burnt to corresponding key directories, and compared with the method of burning keys through an external interface, the method is faster.
The burning means in this step can refer to the specific means for burning the reference key, and the difference is that the burning through the external interface is manual when the reference key is burned. The residual key burnt in the step is prestored in the digital television board card, burning is automatically completed by the digital television board card, and the digital television board card can be considered to burn the residual key which is locally prestored to the corresponding key directory respectively, so that the time for burning the key by the digital television board card is saved, the efficiency of a production line is improved, and the productivity of the digital television board card is improved.
The method for burning the key comprises the steps of firstly burning a reference key acquired through an external interface, then determining a local storage path of a residual key corresponding to the reference key from a key set to be burnt by taking the reference key as a reference, and burning the corresponding residual key under the local storage path. According to the technical scheme, only one reference key is burnt on the production line, the burning of the rest keys is automatically completed by the digital television board card, manual burning through an external interface on the production line is not needed, the time for burning the keys on the production line is effectively saved, the efficiency on the production line is improved, and the capacity of the digital television board card is improved.

It can be understood that the at least two digital television board cards can select respective corresponding reference keys from the key set to be burned to determine respective corresponding remaining keys. Because the reference key is burned by an operator through an external interface, the step only needs to temporarily store the key and the key number association table when the data required by burning the key is prestored. The temporary storage key comprises keys to be burned in the key set to be burned except the reference keys corresponding to the digital television board cards, namely the remaining keys corresponding to the digital television board cards.
The key number association table may be understood as a table for characterizing the local storage path of the key. Such as a table characterizing the remaining key local storage path. The key number association table may store an association relationship between the reference key number corresponding to each digital television board card and the remaining key number corresponding to each digital television board card. After the reference key number corresponding to the reference key is determined, the corresponding residual key number can be uniquely determined by searching the key number association table, so that the corresponding local storage path is determined.

The digital television board card 1 to-be-burned key may include: hdcp key, mac key, windows key and planeady key; the key to be burned of the digital television board card 2 may include: mac key, miracast key, hdcp key, and windows key.
Before production line production, the reference key of the digital television board 1 can be selected as hdcp key, and the reference key of the digital television board 2 can be selected as mac key. Then, a mapping relationship is established between the keys to be burned remaining on each digital television board card and the respective corresponding reference keys, for example, the mapping relationship established by the digital television board card 1 is as follows: hdcp0001- > mac 0001- > widine 0001- > planeand 0001, if the rest keys are included, the subsequent keys are analogized in turn. In the mapping relationship, the number corresponding to each key may be composed of a corresponding function and a local storage path of the key corresponding to the function, which is not limited herein, as long as the corresponding local storage path can be determined based on the information in the mapping.
And similarly, constructing the mapping relation of the digital television board card 2. The mapping relations of the digital television board card 1 and the digital television board card 2 are combined to form a key number association table. Based on the key label table and the reference key, the keys required to be burned by the digital television board 1 and the digital television board 2 can be respectively determined.
When burning the key, the temporary storage key and the key number association table can be locally stored in the set directory in the step, the specific position of the set directory is not limited, and people in the field can select the temporary storage key and the key number association table according to actual conditions, so long as the corresponding key can be read in the set directory when burning the key.

S203, acquiring a reference key number of the reference key.
In the present embodiment, the reference key number may be understood as a number of the reference key stored in the key number association table. The corresponding remaining key number can be determined based on the reference key number.
After the reference key is burned, the reference key number of the reference key can be read in the step, and the reference key number can be carried when the reference key is burned.
S204, searching the reference key number from the key number association table corresponding to the key set to be burned, and obtaining the residual key number corresponding to the reference key number.
In this embodiment, the key number association table may be a table that is constructed based on the key set to be burned and used for determining the local storage path of the key. The key number association table stores the association relationship between the reference key number corresponding to each digital television board card and the residual key number corresponding to each digital television board card. After the reference key number is obtained, the local storage path of the remaining key can be further determined. Specifically, in this step, the reference key number may be searched from the key number association table, and after the reference key number is found, the remaining key number corresponding to the reference key number is determined. If the reference key number is found to be: hdcp0001, corresponding to the remaining key number: mac 0001, windows 0001, and planeady 0001. So that the corresponding local storage path can be further determined.
S205, obtaining the local storage path corresponding to each residual key from the preset number address association table.
In this embodiment, the number address association table may be understood as an association table of key numbers and corresponding local storage paths. Based on the number address table, the local storage path corresponding to the remaining key number can be determined.
After the residual key number is obtained, the local storage path corresponding to the residual key number in the number address association table is searched and obtained.
S206, after monitoring that the burning of the residual keys correspondingly stored in each local storage path is completed, deleting the temporary storage keys and the key number association table stored in the set directory.
In this embodiment, in order to enable the digital television board to automatically complete the burning of the remaining keys, the temporary storage key and the key number association table are stored in the set directory. Therefore, after the burning of the remaining keys correspondingly stored in each local storage path is completed, the temporary storage keys and the key number association table stored in the set directory need to be deleted to increase the storage space.
The monitoring means for whether the key burning is completed or not is not limited herein, and those skilled in the art can determine the key burning by adopting different monitoring means. For example, it can be found whether a burned key exists in the corresponding key directory.
And S207, obtaining the corresponding stored residual key from each local storage path.
When the corresponding remaining keys are obtained and burned according to the local storage paths, the step may first obtain the corresponding stored remaining keys from the local storage paths for burning. Here, the acquisition timing of each remaining key is not limited, and the remaining keys may be acquired in parallel or may be acquired sequentially.
