A method and device for implementing secure communication

Abstract

The invention discloses a method and a device for realizing safe communication. Wherein said method comprises: when detecting the phone call operation on the mobile terminal, judge whether the safe call function is opened; out, and decrypt the received voice data of the other party according to the encryption and decryption algorithm in the designated storage module. In this way, the voice data transmitted during the call is encrypted, which ensures the security of the call and can meet the confidentiality requirements of the enterprise.

Description

technical field [0001] The present invention relates to the field of information security, in particular to a method and device for realizing secure communication. Background technique [0002] With the maturity and popularization of mobile terminals, personal mobile terminals represented by mobile phones and tablet computers have gradually entered the enterprise field. This phenomenon is called Bring Your Own Device (BYOD). Compared with the traditional informatization model, there are three major security risks in the BYOD environment: first, it is connected through a mobile network link, which is naturally in an open network, while traditional important information systems are connected through the enterprise intranet. secondly, the usage environment is different from the traditional informatization model, most of the traditional time is in a fixed office, and the possibility of device loss is very small, while BYOD usually uses mobile terminals, which are more likely to ...

Compared with the traditional informatization model, there are three major security risks in the BYOD environment: first, it is connected through a mobile network link, which is naturally in an open network, while traditional important information systems are connected through the enterprise intranet. secondly, the usage environment is different from the traditional informatization model, most of the traditional time is in a fixed office, and the possibility of device loss is very small, while BYOD usually uses mobile terminals, which are more likely to be lost; thirdly, BYOD uses Many personal APPs are often installed on personal devices at the same time, and there are a lot of malware in the personal APP market, which puts corporate data at risk of security

[0003] Therefore, in the process of enterprise employees using mobile terminals to make calls, the content of the call may be monitored, resulting in the problem of leaking
