Scope

Scope: This document specifies the digital signature format specifications, digital signature object specifications, and digital signature data structure specifications for applications based on the Android operating system. This document is applicable to all parties involved in Android applications who need to standardize the use of the Android application digital signature format. It can be used to guide professional institutions, system developers, security vendors, and electronic certification service providers in developing and building APP signature service systems. Main technical content: Android application authentication and signing use public key cryptography to ensure the integrity of the application and the non-forgeability and non-deniability of its behavior. In practical applications, Android applications need to go through multiple stages such as development, testing, and distribution during their life cycle, and each stage has requirements for integrity, non-forgeability, and non-deniability. Therefore, Android applications need to be signed multiple times and leave traces. This document, as Part 3 of the Android application authentication and signing technical specifications, aims to guide all parties involved in Android applications to adopt the same data format for signing Android applications during their development, testing, and distribution, so as to facilitate the mutual recognition of signatures at different stages of the Android application life cycle.
