To resolve the more and more serious problems of sensitive data transmission for Android smartphone,a method for secure data transmission was studied and presented by adopting secure computation environment of secure digital key(SDKEY).Firstly,a kind of dual-authentication scheme for login using SDKEY and personal identification number(PIN)was designed.Secondly,a solution on transparent encryption storage and transmission for sensitive SMS was proposed.Finally,a method of transparent encryption transmission between Android smartphones was presented,and several kinds of key mechanism for different scenarios were designed to implement key exchange.In this paper a prototype system based on the above solution was developed,its performance verified by the experimental tests,and its security analyzed in detailed.The final results show that the security of prototype system with high performance can be improved by adopting SDKEY.
