Abstract

The invention relates to a service signature method compatible with Android application. The service signature method compatible with Android application comprises the steps of S1 making a list of all of application program software package data files except developer signatures and finishing service signature operation compatible with the Android application; S2 performing verification on the service signatures compatible with the Android application by using a service self identification certificate or a certificate public key. The service signature method compatible with the Android application performs digital signature on the same Android application program package, does not conflict with a developer signature of an application program and can reserve user data when different release versions type application programs obtained through multi-party re-signature are updated and installed. In addition, service-side signature data are stored in catalogues related to service-side domain names and service names, different service-side signature data are not interfered, different service signatures are not influenced, and the problem that signature file names of a traditional application signature mechanism are easily bumped is fundamentally solved. The invention further discloses a service signature device compatible with the Android application.

Description

technical field

[0001] The present invention relates to the field of computer technology, in particular to a service signature method and device compatible with Android applications. Background technique

[0002] Digital signature is an information security technology based on message digest operation and asymmetric encryption operation to ensure the integrity, authentication and non-repudiation of information transmission. Digital signature technology has been widely used in social life, and the digital signature of Android applications is a typical application scenario of the above technology.

[0003] Specifically, the operation process of Android application digital signature at this stage is: use the digest algorithm to calculate each information file in the Android application package except the META-INF directory into a fixed-length hash value, and combine the hash value and the corresponding The file names are sequentially stored in the META-INF / MANIFEST.MF file; co...
