Research On The Code Protection Technology Of Smart Watch

With the development of mobile technology, many traditional electronic products have begun to increase the function of mobile. Smart watch is equipped with embedded system, used to enhance the timekeeping function based on wrist watches, which similar to a personal digital assistant.Pebble is a smart watch. You can connect Pebble with i Phone or Android phone via Bluetooth and using the App Store to download Pebble applications. In addition, developers can also use Pebble official SDK to write their own watch applications.The format of the Pebble smart watch application documents for the pbw is actually a zip file, through decompression can access to the bin format executable file, the attacker by disassemble the software can disassemble the key part of the program’s code.This paper do a more in-depth study on these issues and put forward a Pebble smart watch application code protection scheme. Through the research of Pebble applications development mechanism, using its built-in bluetooth module to transmit data with Android applications. First, make the key part code of the Pebble smart watch applications encrypted and stored in the Android smart applications. Then during the execution of a program, transmit the data to Pebble watch and decrypt it and dynamic loading. Through this scheme, it can protect the Pebble smart watch applications program code.In this paper, we first introduce the backgr ound, purpose and significance of the research, and describe the structure of the thesis.then introduce the Pebble smart watches and Android platform architecture. Then propose a Pebble smart watch application code protection scheme, and then make a detail ed description of the implementation process of the proposed code protection scheme. At the end of this paper, we summarize the work of the research.
