ENCRYPTION IMPLEMENTATION OF ROCK CIPHER BASED ON FPGA

Information security systems must provide high levels of correctness, and reliability. The presented implementation is an application for symmetric encryption algorithm which developed by using two keys to encrypt an input block consist of 128 bit. This implementation is developed for the purpose of producing a powerful encryption data. The operation of encryption and decryption required to insert two keys together so it well done correctly. Each key is used randomly in each round of encryption. The design is based on Field Programmable Gate Array (FPGA) and used VHDL code to implement the design. The simulation results are considered reliable and completely correc
