Abstract

The invention discloses a short message encryption method based on an android operating system, an encryption interface code is added at a short message sending part of a Java framework layer of the android operating system, an encryption implementation code is added at a local framework layer of the android operating system and a first JNI interface is arranged between the encryption interface code and the encryption implementation code, the Java framework layer of the android operating system acquires a short message from an application layer of the android operating system, the encryption interface code is triggered to call the encryption implementation code through the first JNI interface to encrypt the short message, and an encrypted short message is generated; and the encrypted shortmessage is sent to a receiving party. Based on the method, short message encryption is solidified to be a part of the android operating system, potential safety hazards, such as being unloaded, beingdecompiled and being simulated, are removed, and universality is relatively higher. Moreover, the invention also discloses a decryption method corresponding to the encryption method, and the androidoperating system.

Description

technical field [0001] The present invention relates to the technical field of mobile communication encryption, more specifically, relates to a short message encryption and decryption method based on the Android operating system and the Android operating system. Background technique [0002] The short message is transmitted through the wireless channel, and the wireless channel is an open channel. Anyone with appropriate wireless equipment can illegally obtain the specific content of the short message by eavesdropping on the wireless channel. Therefore, the above-mentioned short message transmission method has great security. Hidden dangers can easily cause the specific content of the short message to be leaked, intercepted or tampered with. [0003] In the prior art, there are several methods for encrypting short messages, such as hardware, special SIM card, server and software. Among them, the hardware method is to modify the terminal and add a hardware module to realize ...
