Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] A UMTS mobile terminal circuit domain voice encryption communication technology implementation method, comprising the following steps:
[0028] S1. System hardware architecture design: The hardware architecture of the terminal system used adopts the structure of AP+CP (application processor + communication processor). Since the CP (communication processor) runs an independent mobile TEE (trusted execution environment) operating system, The system is controllable, credible, and safe. In order to ensure the credible and safe storage and processing of voice sources, TPM (Trusted Platform Module) is used as the peri...
