Provably Secure APK Redevelopment Authorization Scheme in the Standard Model
M. X. Luo, Dao-Feng Li, Bowen Zhao, Xianghong Che · 2018
The secure issues of APK are very important in Android applications. In order to solve potential secure problems and Copyrights issues in redevelopment of APK files, we propose a new APK redevelopment mechanism (APK-SAN) which is based on the sanitizable signature scheme in this paper. By exploring unique properties of sanitizable signature technology, APK-SAN allows the original developer to authorize specified modifier who may redevelop the designated source code of APK files. Our scheme does not require interactions between developer and modifier. It can reduce the communication overhead and computational overhead for developers. Especially, the signature of redeveloped APK files is valid and maintains Copyrights. The proposed APK-SAN signature can effectively protect the security of the redeveloped APK files and Copyrights of developer and modifier.
