| Abstract | To resolve the more and more serious problems of sensitive data leakage from Android systems, a kind of method of data protection on encryption storage and encryption transmission is presented in this paper by adopting secure computation environment of SDKEY device. Firstly, a dual-authentication scheme for login using SDKEY and PIN is designed. It is used for login on system boot and lock screen. Secondly, an approach on SDKEY-based transparent encryption storage for different kinds of data files is presented, and a more fine-grained encryption scheme for different file types is proposed. Finally, a method of encryption transmission between Android phones is presented, and two kinds of key exchange mechanisms are designed for next encryption and decryption operation in the following. One is a zero-key exchange and another is a public key exchange. In this paper, a prototype system based on the above solution has been developed, and its security and performance are both analyzed and verified from several aspects. |
