Embodiment Construction

[0050] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0051]The present invention proposes a kind of code all-encompassing encryption method based on RC4 algorithm, the Html, Javascript, Css source code encryption method based on standard RC4 symmetric encryption algorithm, mainly used in the field of mobile application (APP) development. The present invention encrypts the Html, Javascript, and Css codes of the APP on the server side, encrypts the abstract of the digital certificate of the APP, and compiles the APP installation package; when the mobile terminal user installs and star...

Abstract

The invention provides an RC4 algorithm-based code full-packet encryption method. The method comprises the steps of subjecting the codes of an APP to encryption treatment by a server based on an RC4 algorithm; after the APP is started to run, extracting an MM1 and an SS2, and restoring the MM1 and the SS2 to a global ciphertext secret key M1 and an abstract ciphertext S2 based on a secret key private algorithm; obtaining an abstract secret key M3 from the abstract of the M1, and adopting the M3 as a secret key to encrypt the digital certificate signature digest S3 of the APP based on the RC4 algorithm so as to obtain a certificate abstract ciphertext S4; judging whether the certificate abstract ciphertext S4 is consistent with the abstract ciphertext S2 or not; and decrypting the code encryption file of the APP by a client. According to the invention, based on the combination of a standard RC4 symmetric encryption algorithm and a private key generation algorithm, the effects of high efficiency and good safety are achieved at the same time.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an RC4 algorithm-based all-inclusive code encryption method. Background technique [0002] Since the birth of HTML5 technology, the encryption protection of Html, Javascript, and CSS codes is still a huge problem. Mobile APP developed based on HTML5 cross-platform technology, by decompressing its installation package, you can use any code editor to directly view the source code, resulting in product ideas being copied, core code stolen, private data leaked, and intellectual property rights violated And a series of problems, serious ones even affect the security of the server. [0003] Well-known cross-platform APP development technology providers at home and abroad, such as Phonegap, Appcelerator, etc., have no good countermeasures for the encryption and protection of Html, Javascript, and Css codes. Simple protection, but the code is still readable plain text, does no...
