It is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. example. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention.
- the basic idea of the present application is to partially encrypt the media data, so that the transmitted data is mixed with the encrypted data and the unencrypted data, and only the encrypted partial data is decrypted on the requesting side, thereby ensuring the media.
- system resource overhead is effectively reduced.
- a first embodiment of the present invention provides a method for implementing media data processing. As shown in FIG. 1 , the method includes: Step 110: A sender divides media data into a plurality of data blocks.
- the data segmentation generated by the sender to segment the media data may be a fixed length or an unfixed length; of course, those skilled in the art can easily understand that For the segmentation of the media data, other methods in the prior art may be used. This embodiment is not specifically limited, and details are not described herein again.
- Step 120 The sender selects a part of the data blocks in the plurality of data blocks for encryption by using a preset rule shared by the requesting party, and sends the encrypted partial data block and the unencrypted another part of the data to the block.
- the preset rule adopted by the sender must be the same as the preset rule adopted by the requester mentioned in the following steps, because the preset rule is for the sender and the request.
- the parties are the same, so they can serve as the secrets of both the sender and the receiver, just like the key; and the sending and receiving parties can share the preset rules in the following ways, but are not limited to this: the pre-prepared through the secure channel Setting a rule to the requesting party, or informing the requesting party of the preset rule in an open manner, or setting a rule identical to the requesting party in advance, or negotiating and determining the preset rule by performing information interaction with the requesting party. This article will not be described in detail herein.
- the requesting party will use a decryption device as an example for description.
- the number of partial data partitions selected from a plurality of data partitions in the embodiment must be smaller than the total number of the plurality of data partitions, thereby enabling partial encryption.
- the selection operation may be completed by using a preset rule in the following manner, but is not limited thereto:
- a random number generator may be used to implement the selection operation.
- the preset rule should include at least a random number generation algorithm, and may further include a random number to generate an initial value and the like;
- the random number generator has various implementation methods, which are not described herein as well-known methods. It should be noted that, in the embodiment, 0 and 1 in the 0-1 sequence are only two relative distinguishable indications, and any one of them can be used to indicate that the corresponding data partition should be Encrypted or not encrypted; and the 0 and 1 themselves are only examples of the two states in this embodiment, and the embodiment does not specifically limit this.
- the specific algorithm for performing data block selection needs to be determined first: For example, when the preset rule includes The three selection algorithms are: the identifier X represents the selection of the even number, the identifier y represents the selection of the odd number, and the identifier z represents the selection from the first data block to select every two data blocks; based on the preset rule, the identifier is first used. X determines that the selection algorithm is to select an even number, and then extracts all even data blocks from the media data to perform subsequent encryption operations. Work.
- the preset rule is not known, it cannot know which data block is encrypted. Specifically, if the content of the preset rule is not known, the correct data recovery cannot be performed, so the encryption is performed. In addition to the security of the media data can be further increased.
- Step 130 The requesting party receives the media data, and determines, by using a preset rule shared by the sender, the encrypted data block in the media data:
- the media data received by the requesting party includes partially encrypted data blocks and other unencrypted data blocks, and then the requesting party utilizes a pre-shared with the sender.

- the content preparation unit encrypts M data blocks in the N data blocks and distributes them to a server supporting the HTTP protocol; when the server receives the request from the client, the client is The requested segment is delivered to the client.
- the length L of the data block or the number N of encrypted data blocks is transmitted as a parameter to the requesting party.
- the content preparation unit in the embodiment uses a random number generator to randomly generate a 0-1 sequence, wherein the total number of the 0s and 1s in the 0-1 sequence is N, and the number of the 1 is M, and the ith data block corresponds to the i-th bit in the sequence. If the number corresponding to the i-th data block is 1, it indicates that the i-th data block should be encrypted, and the content preparation unit performs an encryption operation on the data block, and performs M data points.
