Abstract

The invention provides a data processing system for voice communication. The data processing system comprises a first security chip, a first output module, a first prompt module, a first transmission module, a second transmission module and a second security chip. The first security chip is used for obtaining and verifying a digital certificate of a second security device; the first output module is used for outputting identification information of the digital certificate of the second security device, the first prompt module is used for conducting prompting to confirm the identification information of the digital certificate of the second security device; the first security chip is further used for starting encryption and decryption operation of voice communication; the first security chip is further used for encrypting a communication secret key to obtain ciphertexts of the communication secret key and conducting signature processing on the ciphertexts of the communication secret key to obtain signature data; the first transmission module is used for transmitting the ciphertexts of the communication secret key and the signature data; the second transmission module is used for receiving the ciphertexts of the communication secret key and the signature data; the second security chip is used for decrypting the ciphertexts of the communication secret key to obtain the communication secret key when verification on the signature data is successful; the second security chip is further used for starting encryption and decryption operation of voice communication.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a data processing system for voice calls. Background technique [0002] In the prior art, voice calls between users may be monitored, so current voice calls have security risks. Aiming at security risks, the method adopted in the prior art is to encrypt the voice through the call key stored in the TF card on the mobile phone, so as to realize the protection of the voice call. However, in practical applications, if the call terminal is installed with malware, hackers can use the malware to steal the call key in the TF card, and then crack the encrypted voice information, resulting in the risk of voice data leakage of the call terminal. The voice encryption operation is a technical problem to be solved urgently; in addition, in the prior art, there is a possibility of being monitored in a voice call, so reducing the possibility of a voice call being monitored is also a technic...
