Abstract

The invention provides a security device which is independent of a calling terminal and is connected with the calling terminal through a communication interface. The security device comprises a security chip, an output module and a prompt module; the security chip is used for obtaining a digital certificate of a target security device and performing verification on the digital certificate of the target security device through a root certificate in the security device; the target security device is a security device of a target calling terminal, wherein a voice call is performed between the target calling terminal and the calling terminal; the output module is used for outputting the identification information of the digital certificate of the target security device after the verification of the digital certificate of the target security device passes; the prompt module is used for prompting the confirmation on the identification information of the digital certificate of the target security device.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a safety device. 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 technical problem to be solved u...
