Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an encryption method, an encryption device and a mobile terminal for a mobile terminal. Background technique [0002] At present, with the rapid development of mobile communication technology, network operators require that certain networks or frequency bands of SIM cards of non-cooperating operators cannot be registered and used for the protection of their own interests. In addition, equipment manufacturers, in order to reduce production and maintenance costs, uniformly use multi-band and multi-mode production for mobile phone motherboards during production. However, some operators only need some frequency bands, and usually use software to shield them, but this may cause malicious flashing and cause losses to equipment manufacturers. [0003] Therefore, it is necessary to adopt an encryption method to solve the problems of operators and equipment manufacturers. In...
