Embedded Device Security and Access Control of Quadcopter with a Taser through Encryption
V Mekaladevi, D. Ram Kumar Reddy, N. Mohankumar · 2018
Security is one of the major problems which have to be acknowledged, the problem of information security and security in defense is being taken into primary consideration in this paper. Securing any device through remotely controlling its access is the need of the hour. A triple fold access control of Quadcopter mounted with a Taser gun is proposed here. As a primary solution to security and for preventing any misuse, the quadcopter's access is controlled through an access code. An adversary may attempt to decode the access code, in order to gain access. This is denied by the proposed asymmetric shift based ciphering; a form of encrypting the access code in unique way which provides a second level of security. A time efficient encryption/decryption algorithm is developed and used which will be executed with the help of the GSM shield and the Arduino board and its response time is found to be less than one second, since Huffman data compression method is used for reducing the size of the file transmitted. GSM shield is also providing a third level of security by accepting the encrypted access code through a GSM number specified by the user. The GSM module is then deployed to invoke a web based URL to send and store data on the privately authorized cloud, which can be retrieved when necessary for further analytics.
