VLSI implementation of advance encryption algorithm using index technique

Symmetric algorithm is a popular encryption algorithms. The proposed algorithm is a class of symmetric algorithm providing an advance security because unlike other symmetric algorithms, the key is not available for users, it is covered and fixed inside the lookup table (LUT) as a part of the FPGA, the design has a fixed operation of encryption created on FPGA device using VHDL language. The paper shows the results of performance and hardware utilization.
