The invention discloses a software protection method and a software application method of an android system, and related devices. The software protection method comprises the steps of acquiring a first code corresponding to to-be-protected software; replacing a function code of an application programming interface (api) in the first code with an api character string code for api call through a character string way, so as to obtain a second code corresponding to the to-be-protected software; performing code derangement on the character string in the api character string code in the second code through a derangement processing program, so as to obtain a third code corresponding to the to-be-protected software; and packaging the third code and a derangement recovery program corresponding to the derangement processing program, so as to obtain a newest android package (apk) of the to-be-protected software. Compared with the prior art, the method increases the difficulty in reverse analysis of apk, so that the apk is protected to a greater extent.
Description
technical field [0001] The present invention relates to the field of information security, in particular to a software protection method for an Android system, a software application method and related devices. Background technique [0002] With the rapid development of the mobile Internet, there are more and more smart mobile terminals, among which the Android (Android) system occupies a large proportion of the mobile terminal systems. The mainstream development language of the software installation package (apk, AndroidPackage) on the Android system is Java. Compared with other software development languages, the Java language is easier to decompile and reversely modify. Therefore, the attacker embeds malicious code by decompiling the apk , Cracking the billing point of paid software, embedding spam plug-ins, etc., may lead to user information leakage, information loss, and bring losses to users. On the other hand, the copyright of the software cannot be guaranteed, bringi...
