Referring to fig. 1, a broadcast data interaction apparatus 10 according to a first embodiment of the present invention is provided, where the broadcast data interaction apparatus 10 includes: a broadcast data server 11, and a broadcast terminal 12 connected to the broadcast data server 11.
The broadcast data server 11 may be communicatively coupled to one or more broadcast terminals 12 via a network for data communication or interaction. The broadcast data server 11 may be a web server, a database server, or the like. In this embodiment, the broadcast data server 11 is configured to acquire broadcast data input by a user, encrypt and generate signature data corresponding to the broadcast data according to the broadcast data, and send both the broadcast data and the signature data to the broadcast broadcasting terminal 12.
The broadcast terminal 12 may be an integrated circuit device with signal processing and amplification capabilities, and the broadcast terminal 12 may be at least one. The broadcast terminal 12 can obtain the signature data and the broadcast data sent by the broadcast data server 11, and then the broadcast terminal 12 broadcasts the broadcast corresponding to the broadcast data according to the signature data and the broadcast data.
Referring to fig. 2, the broadcast data server 11 includes: the device comprises an acquisition module 111, an encryption module 112 connected with the acquisition module 111, and a sending module 113 connected with the encryption module 112.

A determining module 121, configured to determine whether the signature data matches the broadcast data.
A playing module 122, configured to play the broadcast corresponding to the broadcast data according to the broadcast data when the determination of the determining module is yes.
Second embodiment
Referring to fig. 3, a second embodiment of the present invention provides a broadcast data interaction method, which is applied to a broadcast data interaction device. The broadcast data interaction method comprises the following steps: step S100, step S200, and step S300.
Step S100: the broadcast data server obtains broadcast data.
When a user needs to broadcast a data interaction device to send an emergency broadcast, the emergency broadcast may be a broadcast with strong urgency and importance. The user may operate at his/her mobile terminal or directly at the broadcast data server to generate broadcast data to the broadcast data server through the operation, and the server may acquire the broadcast data input based on the user's operation.
Step S200: and the broadcast data server encrypts and generates signature data corresponding to the broadcast data according to the broadcast data, and sends the broadcast data and the signature data to the broadcast broadcasting terminal.
After the broadcast data is acquired, the broadcast data server needs to analyze the broadcast data, so as to determine whether the broadcast data needs to be encrypted through analysis, and perform subsequent broadcast.
And when the broadcast data server judges that the broadcast data is the broadcast data which needs to be encrypted, the broadcast data server generates signature data corresponding to the broadcast data according to a preset private key encryption program. After encryption, the data obtained by the broadcast data server are respectively signature data and broadcast data, and then the broadcast data server sends both the signature data and the broadcast data to the broadcast broadcasting terminal.
Step S300: and the broadcast broadcasting terminal broadcasts the broadcast corresponding to the broadcast data according to the signature data and the broadcast data.
Correspondingly, after the broadcast data server sends both the signature data and the broadcast data to the broadcast broadcasting terminal, the broadcast broadcasting terminal correspondingly acquires the signature data and the broadcast data. At this time, to further ensure security, the broadcast broadcasting terminal needs to verify the signature data and the broadcast data to prevent the possibility of data forgery, for example, the signature data being forged by a hacker.
Specifically, the broadcast broadcasting terminal decrypts the signature data by using a public key decryption corresponding to the private key encryption, and correspondingly analyzes the broadcast data. And then, the broadcast broadcasting terminal matches the decrypted signature data with the analyzed broadcast data and judges whether the signature data is matched with the analyzed broadcast data. And if the broadcast terminal judges that the signature data and the broadcast data are not matched, the security of the signature data and the security of the broadcast data are problematic, and both the signature data and the broadcast data are deleted. If the broadcast broadcasting terminal judges that the signature data and the broadcast data are matched, the signature data and the broadcast data are safe, and then the broadcast data server can broadcast the broadcast corresponding to the broadcast data according to the broadcast data.
Referring to fig. 4, in a broadcast data interaction method according to a second embodiment of the present invention, a method sub-process of step S200 includes: step S210 and step S220.
Step S210: and the broadcast data server judges whether the acquired broadcast data meets a preset standard.
The broadcast data server acquires data that needs to be encrypted. Therefore, after the broadcast data server acquires the data, the broadcast data first judges whether the data meets a preset standard. If yes, the data is the broadcast data which needs to be encrypted, if not, the data is other data, and other operation processing is carried out. It can be understood that after the broadcast data server obtains the broadcast data, the broadcast data server also needs to perform corresponding judgment.
Specifically, after the broadcast data server obtains the broadcast data, the broadcast data server analyzes the broadcast data to obtain the identification data in the broadcast data. The identification data is used to identify the broadcast data, and may be, for example: any natural number of 0 or 1. The broadcast data server is preset with preset identification data and is provided with a corresponding relation between the preset identification data and the identification data. And the broadcast data server matches the acquired identification data with preset identification data to judge whether the identification data and the preset identification data meet the corresponding relation. For example, the identification data is 0, the preset identification data is 1, and the corresponding relationship is 0 and 1. It can be understood that, if the acquired data is not broadcast data, the identification data in the data cannot satisfy the corresponding relationship, and the data cannot satisfy the preset standard, so that the broadcast data server performs other operations on the data. If the acquired data is broadcast data, the broadcast data server can judge that the identification data in the broadcast data and the preset identification data meet the corresponding relation, the identification data is matched with the preset identification data, and the broadcast data further meets the preset standard.
Step S220: if the broadcast data server determines that the signature data is true, the broadcast data server encrypts and generates the signature data corresponding to the broadcast data based on the broadcast data.
When the broadcast data server judges that the broadcast data is the broadcast data, the broadcast data server performs an encryption operation based on the broadcast data. Specifically, the broadcast data server extracts the appointed data segment in the broadcast data through a preset SM3 algorithm (a sender middle 3, a cryptographic hash algorithm). The appointed data segment is used for generating signature data, and in an actual implementation process, the appointed data segment may be determined according to actual requirements, which is not specifically limited in this embodiment. The broadcast data server is also preset with a private key encryption algorithm of SM2, and after the broadcast data server acquires the appointed data segment, the broadcast data server encrypts the appointed data segment based on the private key encryption algorithm of SM2 to generate signature data corresponding to the broadcast data. Further, the broadcast data server sends the obtained signature data and broadcast data to the broadcast broadcasting terminal.
Referring to fig. 5, in a broadcast data interaction method according to a second embodiment of the present invention, a method sub-process of step S300 includes: step S310 and step S320.
Step S310: and the broadcast broadcasting terminal judges whether the signature data is matched with the broadcast data.
After the broadcast broadcasting terminal acquires the corresponding signature data and broadcast data, the broadcast broadcasting terminal needs to verify the signature data and the broadcast data to ensure the security.
Specifically, the SM3 algorithm is also preset in the broadcast terminal, and after the broadcast data is acquired, the broadcast terminal extracts the appointed data segment in the broadcast data through the SM3 algorithm. In addition, the public key decryption algorithm of the SM2 is also set in advance in the broadcast terminal. According to the public key decryption algorithm of the SM2, the broadcast terminal also decrypts the signature data accordingly, thereby obtaining the appointed data segment in the signature data. Further, the broadcast broadcasting terminal matches the appointed data segment in the broadcast data with the appointed data segment in the signature data.
Step S320: and the broadcast broadcasting terminal plays the broadcast corresponding to the broadcast data according to the broadcast data when judging that the broadcast is positive.
In the process that the broadcast broadcasting terminal matches the appointed data field in the broadcast data with the appointed data field in the signature data, the broadcast broadcasting terminal matches each data in the appointed data field of the broadcast data with each data in the appointed data field of the signature data in sequence. When any one of the data is not matched, the broadcast broadcasting terminal judges that the appointed data segment in the broadcast data is not matched with the appointed data segment in the signature data, the broadcast data and the signature data have a safety problem, and the broadcast data and the signature data are deleted. When each piece of data is matched, the broadcast broadcasting terminal judges that the appointed data segment in the broadcast data is matched with the appointed data segment in the signature data, namely the broadcast broadcasting terminal judges that the appointed data segment is matched with the appointed data segment in the signature data, the security is proved to be free of problems, and the broadcast data server can broadcast the broadcast corresponding to the broadcast data according to the broadcast data.
In summary, the embodiments of the present invention provide a broadcast data interaction method and apparatus. The broadcast data interaction method is applied to a broadcast data interaction device, and the device comprises the following steps: the broadcast data server is connected with the broadcast broadcasting terminal. The method comprises the following steps: the broadcast data server acquires broadcast data; the broadcast data server encrypts and generates signature data corresponding to the broadcast data according to the broadcast data, and sends the broadcast data and the signature data to the broadcast broadcasting terminal; and the broadcast broadcasting terminal broadcasts the broadcast corresponding to the broadcast data according to the signature data and the broadcast data.
The broadcast data server acquires the broadcast data, generates signature data corresponding to the broadcast data according to broadcast data encryption, then sends the broadcast data and the signature data to the broadcast broadcasting terminal, and then the broadcast broadcasting terminal broadcasts the broadcast corresponding to the broadcast data according to the signature data and the broadcast data. Since the encryption is performed by the broadcast data server to generate signature data corresponding to the broadcast data, the security of the encryption process is enhanced. And by updating the data of the broadcast data server, the mode of encrypting the signature data can be updated at any time, so that the application is flexible and the applicability is strong.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
