Abstract: The Block cipher AES is a symmetric key cryptographic standard used for transferring block of data in secure manner for server based communication networks, SCADA systems for Oil refinery, Oil and Gas Pipe Lines, and Smart Grids based applications. High level security of data transfer needs long key size i.e. 256 bits, analysis of certain ideas of round key expansion mechanisms from given key data are discussed and the same is implemented in FPGA configuration with 128 bits and 256 bits key size to achieve low latency, high throughput with high security.
