FPGAs are used in various applications like aero-space, automotive, military etc. which require them to operate in different types of environments. Security of FPGA based system is a big concern as the system developed after lot of research can be stolen very easily. Now-a-days, a lot of research is going on, considering various security aspects of FPGAs as the primary concern. Several cryptographic systems are available which can be used to protect FPGA bit-streams. Cryptographic techniques are used to encrypt the FPGA bit-streams.
