The invention discloses a method for realizing an encrypted call on a mobile terminal. The method comprises the following steps: a user sends call information to a third-party encryption server; calltransmission data is encrypted based on the mobile terminal by adopting an SIP encryption method; the database cluster manages database node information; the CIN-MS server and the CIN-AS server are ina session; the CIN-MS server manages the call information; the CIN-MS server sends a recording notification to the user according to the instruction information, and collects information dialed by the user; the CIN-AS server acquires and processes the error information; encryption is completed. By applying the method in development, unified security access, identity authentication, data encryption, access control, user behavior auditing and other security functions based on a national cryptographic algorithm are provided for mobile terminal call system application, an SDK tool is provided, seamless butt joint with a conventional application system can be achieved, and the security of VoIP calls is improved.
Description
technical field [0001] The invention relates to the technical field of communication encryption, in particular, to a method for implementing encrypted calls on a mobile terminal. Background technique [0002] Mobile office is becoming more and more popular in enterprises, governments and other units. While improving office efficiency, the security issues of mobile phone calls are also becoming more and more prominent. Identity authentication is fragile, data transmission in plain text, which brings dragging attacks, credentialing attacks, and data interception by hackers. , tampering and other security issues occur from time to time. Due to the high technical threshold, there are relatively few anti-call monitoring products at home and abroad, and the existing more mature products also have some major limitations, such as the cost of shielding rooms is too expensive, and anti-eavesdropping earphones cannot be realized under concealed conditions. Recording masking. Content...
