For mobile database, security is extremely important because of the mobility of the user, the portability of the device and wireless connectivity. Mobile devices used for mobile database applications are highly resource constraint in nature. Limited battery power, less memory capacity and low computing capability are some of the restrictions of mobile devices. Once the battery is drained, the data stored inside the mobile device cannot be accessed. Therefore there is a need to design a new light weight algorithm which can effectively encrypt the mobile database by considering the limitations of the mobile device. The main objective of this paper is to provide light weight cryptography, namely RSK algorithm, to secure the mobile database as well as to prove the efficiency of RSK by doing a comparative analysis with the existing symmetric key encryption algorithms. A new crypto hardware tool is designed along with a software and experiments are conducted using both hardware and software co-design. A comparative analysis is done between RSK and existing encryption algorithms to understand the performance of the newly designed RSK. Experiments are conducted at various levels by changing the inputs such as source file and key given to the encryption algorithms. It is found that RSK algorithm outperforms all the other algorithms, in all the experiments conducted, in terms of Power consumption and Time utilized by both encryption and decryption processes. Also it is proved that the throughput of RSK is higher than all the other algorithms. 收起
