Design and application of encryption system using FPGA for secure communication

In this study, an encryption system has been made in order to obtaininformation security and confidentiality independent from the transmissionmedia. "The hardware-design" has been selected as the encrypting method andan application has been done on a FPGA-VHDL element. Mostly, softwareencryption is sufficient for daily communications, but for the areas where youneed high security hardware-encryption is preferred due to its fast and moresecure capabilities. Advanced Encryption Standard (AES) has been preferredfor the reasons that its security was tested for each kind of attacks and it isapproved by NIST (National Insitute of Standards and Technologies). CodeFeedback method (CFB) has been preferred as the encryption method and as anhardware element SPARTAN (a poduct of XILINX) has been used.
