The invention provides an audio data decryption method and device, and relates to the technical field of audio data processing. In the application, firstly, encrypted audio data sent by an audio acquisition device is obtained, and the encrypted audio data is obtained by encrypting multiple audio frames acquired by the audio acquisition device; secondly, first decryption processing is carried out on the encrypted audio data, a first data packet and a second data packet are obtained, the first data packet comprises decryption identification information, and the second data packet comprises multiple audio frames acquired by audio acquisition device; and then, based on decryption identification information included in the first data packet, a corresponding target decryption mode is determined, and based on the target decryption mode, decryption processing is performed on the second data packet to obtain a corresponding multi-frame audio frame, and the multi-frame audio frame is taken as to-be-processed audio data. Based on the method, the problem of low security of the audio data in the existing decryption mechanism can be improved.
Description
technical field [0001] The present application relates to the technical field of audio data processing, and in particular, to a method and device for decrypting audio data. Background technique [0002] There are many application fields of audio data. Therefore, after the audio data is collected based on the audio collection device, the audio data can be transmitted to the required device for application. Encryption, in this way, after the corresponding device obtains the audio data, it needs to perform decryption processing first. However, the inventors have found through research that, in the prior art, there is a problem that the security of audio data is not high based on the existing decryption mechanism. Contents of the invention [0003] In view of this, the purpose of this application is to provide a method and device for decrypting audio data, so as to improve the problem of low security of audio data existing in the existing decryption mechanism. [0004] In or...
