视频解密方法及装置Video decryption method and device
本申请要求于2016年6月1日提交中国专利局、申请号为2016103797429、发明名称为“视频解密方法及装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。The present application claims the priority of the Chinese Patent Application, the entire disclosure of which is hereby incorporated by reference.
技术领域Technical field
本发明涉及计算机技术领域，尤其涉及一种视频解密的方法及装置。The present invention relates to the field of computer technologies, and in particular, to a video decryption method and apparatus.
背景技术Background technique
随着技术的飞速发展，用户常常利用高清电视观看视频，当用户需要利用高清电视观看视频时，高清电视需要从服务器中获取用户需要观看的视频的原始视频数据。With the rapid development of technology, users often use HDTV to watch video. When users need to watch video on HDTV, HDTV needs to obtain the original video data of the video that the user needs to watch from the server.
其中，服务器在向高清电视发送原始视频数据时，需要先将原始视频数据利用HDCP(High-bandwidth Digital Content Protection，高带宽数字内容保护技术)加密协议进行加密得到加密视频数据，然后再通过HDMI(High Definition Multimedia Interface，高清晰度多媒体接口)向高清电视发送加密视频数据。高清电视通过HDMI接收服务器发送的加密视频数据，然后利用HDCP解密协议对加密视频数据解密得到原始视频数据，进而在高清电视上播放原始视频数据，如此用户就可以在高清电视上观看视频。The server needs to encrypt the original video data by using the HDCP (High-bandwidth Digital Content Protection) encryption protocol to obtain the encrypted video data, and then pass the HDMI (in the case of transmitting the original video data to the HDTV). High Definition Multimedia Interface, which sends encrypted video data to HDTV. The HDTV receives the encrypted video data sent by the server through HDMI, and then decrypts the encrypted video data to obtain the original video data by using the HDCP decryption protocol, thereby playing the original video data on the HDTV, so that the user can watch the video on the HDTV.
其中，高清电视在出厂的时候，技术人员会在高清电视中内置一个解密协议，当高清电视通过HDMI接口接收到服务器发送的加密视频数据时，会利用内置的解密协议对加密视频数据解密。Among them, when the HDTV is shipped from the factory, the technician will build a decryption protocol in the HDTV. When the HDTV receives the encrypted video data sent by the server through the HDMI interface, it will decrypt the encrypted video data by using the built-in decryption protocol.
然而，当前，服务器对原始视频数据加密时能够利用的加密协议有多个，也即，服务器可以从多个不同的加密协议中选择一个加密协议，并利用选择的加密协议对原始视频数据加密；其中，每一个加密协议都与一个解密协议匹配。However, currently, there are multiple encryption protocols that the server can utilize when encrypting the original video data, that is, the server can select one encryption protocol from a plurality of different encryption protocols, and encrypt the original video data by using the selected encryption protocol; Among them, each encryption protocol matches a decryption protocol.
当利用一个加密协议对原始视频数据加密得到加密视频数据之后，如果需要对加密视频数据解密，必须利用与该加密协议相匹配的解密协议对加密视频数据解密，这样才能对加密视频数据解密成功，进而得到原始视频数据；如果利用与该加密协议不匹配的解密协议对加密视频数据解密，就会对加密视频数据解密失败，也就无法得到原始视频数据。 After encrypting the original video data to obtain the encrypted video data by using an encryption protocol, if the encrypted video data needs to be decrypted, the encrypted video data must be decrypted by using a decryption protocol matching the encryption protocol, so that the encrypted video data can be decrypted successfully. Further, the original video data is obtained; if the encrypted video data is decrypted by using a decryption protocol that does not match the encryption protocol, the decryption of the encrypted video data fails, and the original video data cannot be obtained.
因此，如果高清电视中内置的该一个解密协议与对原始视频数据加密得到加密视频数据所利用的加密协议不匹配，则高清电视就无法对加密视频数据解密成功，也就无法得到原始视频数据，进而无法播放原始视频数据，导致用户无法在高清电视上观看视频。Therefore, if the one decryption protocol built in the HDTV does not match the encryption protocol used to encrypt the original video data to obtain the encrypted video data, the HDTV cannot decrypt the encrypted video data successfully, and the original video data cannot be obtained. In turn, the original video data cannot be played, making it impossible for users to watch the video on the HDTV.

具体实施方式detailed description
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。 Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. The following description refers to the same or similar elements in the different figures unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with aspects of the invention as detailed in the appended claims.
图1是根据一示例性实施例示出的一种视频解密方法的流程图，如图1所示，该方法用于终端中，该方法包括以下步骤。FIG. 1 is a flowchart of a video decryption method according to an exemplary embodiment. As shown in FIG. 1 , the method is used in a terminal, and the method includes the following steps.
在步骤S101中，接收通过HDMI传输给终端的加密视频数据，加密视频数据是对原始视频数据加密得到的；In step S101, the encrypted video data transmitted to the terminal through the HDMI is received, and the encrypted video data is obtained by encrypting the original video data;
在本发明实施例中，终端可以为高清电视等用于播放高清视频的终端。In the embodiment of the present invention, the terminal may be a terminal for playing high-definition video such as a high-definition television.
当用户需要利用终端观看视频时，如果终端本地未存储有该视频的原始视频数据，则终端需要从服务器中获取该视频的原始视频数据。其中，终端需要向服务器发送用于视频的视频数据的获取请求；该获取请求携带该视频的视频标识；When the user needs to use the terminal to watch the video, if the terminal does not locally store the original video data of the video, the terminal needs to obtain the original video data of the video from the server. The terminal needs to send an acquisition request for the video data of the video to the server; the acquisition request carries the video identifier of the video;
当服务器接受到该获取请求之后，服务器从该获取请求中提取出该视频标识，根据该视频的视频标识获取该视频的原始视频数据；为了避免原始视频数据在传输给终端的过程中被不法分子窃取，服务器需要利用加密协议对原始视频数据加密得到加密视频数据，然后通过HDMI向终端发送加密视频数据；终端通过HDMI接收服务器发送的加密视频数据。After the server receives the acquisition request, the server extracts the video identifier from the acquisition request, and obtains the original video data of the video according to the video identifier of the video; in order to prevent the original video data from being passed to the terminal in the process of being transmitted to the terminal Stealing, the server needs to encrypt the original video data by using an encryption protocol to obtain encrypted video data, and then send the encrypted video data to the terminal through HDMI; the terminal receives the encrypted video data sent by the server through the HDMI.
在步骤S102中，确定对原始视频数据加密得到加密视频数据所利用的加密协议；In step S102, determining an encryption protocol used to encrypt the original video data to obtain encrypted video data;
在本发明实施例中，可以通过如下两种方式来确定出对原始视频数据加密得到加密视频数据所利用的加密协议，包括：In the embodiment of the present invention, the encryption protocol used to encrypt the original video data to obtain the encrypted video data may be determined in the following two manners, including:
第一种方式：获取加密视频数据中预设加密字段；其中，当服务器在利用加密协议对原始视频数据加密得到加密视频数据之后，会在加密视频数据中的预设加密字段中存储利用的该加密协议的协议标识，协议标识可以为加密协议的版本号或者加密协议的生成时间等，加密协议的生成时间为技术人员创建出加密协议的日期。因此，当获取到加密视频数据中预设加密字段时，终端可以获取预设加密字段中存储的内容并作为加密协议的协议标识；并将该协议标识对应的加密协议确定为对原始视频数据加密得到加密视频数据所利用的加密协议。The first method: obtaining a preset encryption field in the encrypted video data; wherein, after the server encrypts the original video data by using the encryption protocol to obtain the encrypted video data, the server stores the used encrypted field in the encrypted video data. The protocol identifier of the encryption protocol. The protocol identifier can be the version number of the encryption protocol or the generation time of the encryption protocol. The generation time of the encryption protocol is the date when the technician creates the encryption protocol. Therefore, when the preset encryption field is obtained in the encrypted video data, the terminal may obtain the content stored in the preset encryption field and use the protocol identifier as the encryption protocol; and determine the encryption protocol corresponding to the protocol identifier to encrypt the original video data. Obtain the encryption protocol utilized by the encrypted video data.
第二种方式，在本发明另一实施例中，服务器在向终端发送加密视频数据之前，会先向终端发送加密视频数据的属性信息；属性信息至少携带对原始视频数据加密得到加密视频数据所利用的加密协议的协议标识。因此，终端可以判断是否接收到加密视频数据的属性信息；当接收到该属性信息时，从该属性信息中提取出对原始视频数据加密得到加密视频数据所利用的加密协议的协议标识。In a second mode, in another embodiment of the present invention, before sending the encrypted video data to the terminal, the server first sends the attribute information of the encrypted video data to the terminal; the attribute information carries at least the encrypted video data obtained by encrypting the original video data. The protocol identifier of the encryption protocol utilized. Therefore, the terminal can determine whether the attribute information of the encrypted video data is received. When the attribute information is received, the protocol identifier of the encryption protocol used to encrypt the original video data to obtain the encrypted video data is extracted from the attribute information.
在步骤S103中，获取与该加密协议相匹配的目标解密协议； In step S103, acquiring a target decryption protocol that matches the encryption protocol;
其中，在本发明实施例中，不同的加密协议匹配不同的解密协议。在相互匹配的一组加密协议和解密协议中，加密协议的协议标识和解密协议的协议标识相同。Wherein, in the embodiment of the present invention, different encryption protocols match different decryption protocols. In a set of encryption protocols and decryption protocols that match each other, the protocol identifier of the encryption protocol is the same as the protocol identifier of the decryption protocol.
当技术人员创建出一个加密协议时，技术人员就会创建出与该加密协议相匹配的解密协议，如此，当利用创建出的该加密协议对原始视频数据加密得到加密视频数据之后，如果要还原得到原始视频数据，需要利用创建出的与该加密协议相匹配的解密协议对加密视频数据解密，才能得到原始视频数据。When the technician creates an encryption protocol, the technician creates a decryption protocol that matches the encryption protocol. Thus, when the original video data is encrypted using the created encryption protocol, the encrypted video data is obtained. To obtain the original video data, the encrypted video data needs to be decrypted by using the created decryption protocol matching the encryption protocol to obtain the original video data.
在历史过程中技术人员可能创建出了多个不同的加密协议，例如创建出v1.0版本的加密协议之后，对v1.0版本的加密协议升级得到v2.0版本的加密协议，对v2.0版本的加密协议升级得到v3.0版本的加密协议等等。同时，技术人员就会创建多出个不同的解密协议。During the history, the technician may have created a number of different encryption protocols. For example, after creating the v1.0 version of the encryption protocol, the v1.0 version of the encryption protocol is upgraded to obtain the v2.0 version of the encryption protocol, for v2. The 0 version of the encryption protocol is upgraded to obtain the v3.0 version of the encryption protocol and so on. At the same time, the technician will create a different decryption protocol.
每当技术人员创建出一个解密协议，终端就会将创建出的该解密协议的协议标识和创建出的该解密协议组成一条记录并存储在本地存储协议标识与解密协议之间的对应关系中。Whenever the technician creates a decryption protocol, the terminal composes the created protocol identifier of the decryption protocol and the created decryption protocol into a record and stores it in the correspondence between the local storage protocol identifier and the decryption protocol.
因此，在本步骤中，终端可以获取本地存储的协议标识与解密协议之间的对应关系；由于该加密协议的协议标识和与该加密协议相匹配的解密协议的协议标识相同，所以可以在该对应关系中查找与该加密协议的协议标识相对应的解密协议，并作为目标解密协议。Therefore, in this step, the terminal may obtain a correspondence between the locally stored protocol identifier and the decryption protocol; since the protocol identifier of the encryption protocol and the protocol identifier of the decryption protocol matching the encryption protocol are the same, A decryption protocol corresponding to the protocol identifier of the encryption protocol is searched for in the correspondence relationship and used as a target decryption protocol.
在本发明另一实施例中，终端本地存储了技术人员在历史过程中创建的与每一个加密协议相匹配的解密协议，因此，在本步骤中，终端可以在本地存储的多个不同的解密协议中查找与加密协议相匹配的目标解密协议；In another embodiment of the present invention, the terminal locally stores a decryption protocol that is created by the technician in the history process and matches each encryption protocol. Therefore, in this step, the terminal may store multiple different decryptions locally. Finding a target decryption protocol that matches the encryption protocol in the protocol;
在本发明又一实施例中，如果终端本地未存储技术人员在历史过程中创建的与每一个加密协议相匹配的解密协议，则在本步骤中，终端可以从服务器中获取与该加密协议相匹配的目标解密协议。In another embodiment of the present invention, if the terminal does not locally store the decryption protocol that is created by the technician in the history process and matches each encryption protocol, in this step, the terminal may obtain the encryption protocol from the server. Match the target decryption protocol.
在步骤S104中，利用目标解密协议对加密视频数据解密得到原始视频数据。In step S104, the encrypted video data is decrypted using the target decryption protocol to obtain original video data.
在本发明实施例中，接收通过HDMI传输给终端的加密视频数据，加密视频数据是对原始视频数据加密得到的；确定对原始视频数据加密得到加密视频数据所利用的加密协议；获取与该加密协议相匹配的目标解密协议；利用目标解密协议对加密视频数据解密得到原始视频数据。如此，无论加密视频数据是利用何种加密协议对原始视频数据加密得到的，当确定出对原始视频数据加密得到加密视频数据所利用的加密 协议时，获取与该加密协议相匹配的目标解密协议，其中，如果事先在本地存储了与该加密协议相匹配的目标解密协议，则可以直接从本地获取目标解密协议，如果本地未存储与该加密协议相匹配的目标解密协议，则可以从服务器中获取目标解密协议；最后利用目标解密协议对加密视频数据解密时一定能解密成功，一定能够得到原始视频数据，进而保证用户能够在终端上观看视频。In the embodiment of the present invention, the encrypted video data transmitted to the terminal through the HDMI is received, and the encrypted video data is obtained by encrypting the original video data; determining an encryption protocol used to encrypt the original video data to obtain the encrypted video data; acquiring and encrypting The protocol matching target decryption protocol; decrypting the encrypted video data using the target decryption protocol to obtain the original video data. Thus, regardless of which encryption protocol the encrypted video data is encrypted with, the original video data is encrypted, and the encryption used to encrypt the original video data to obtain the encrypted video data is determined. When the protocol is obtained, the target decryption protocol matching the encryption protocol is obtained, wherein if the target decryption protocol matching the encryption protocol is stored locally, the target decryption protocol may be directly obtained locally, if the local is not stored and The target decryption protocol matched by the encryption protocol can obtain the target decryption protocol from the server; finally, the decryption succeeds when decrypting the encrypted video data by using the target decryption protocol, and the original video data can be obtained, thereby ensuring that the user can watch on the terminal. video.
