EMBEDDED SYSTEM BASED ENCRYPTION AND DATA ACQUISITION ON FPGA FOR DEFENSE APPLICATION.

Recent developments in defense technology have changed the warfare scenario. The systems are more intelligent, robust and ruggedized. Defense technology demands high accuracy, precision and consistency. A major and important requirement in the field of defense technology is the security and confidentiality of data and information. The most adopted technique for securing the data or information is encryption of the data. The encrypted information can be later decrypted for safe application. In this paper the author has developed a secure data acquisition and Encryption system based on FPGA for defense application. The system consists of two stages, first is the data acquisition stage where the data will be acquired from real world and will be converted in digital form. In the second stage the acquired data will be encrypted and stored in FPGA memory. Later this encrypted data is decrypted to retrieve the original data. The input data chosen for this system is analog signals, as the concept behind this study is mainly for acquiring data from sensors which can be part of any missile or rocket. The data can be pressure, acceleration, temperature etc. which can be recorded from sensors mounted on intelligent systems.
