Objectives: Vedic mathematics contains 16 formulae or Sutras. Employing these shortcut formulae in the computations of Elgamal cryptographic algorithm will reduce the logic elements, layout area and power consumption. Methods/Statistical Analysis: Simulation programming for the paper has been done through Verilog HDL code in MODELSIM software and performance parameters like speed, power etc., using XILINX software. Findings: In this paper, when employing these Vedic formulae, lesser number of logic elements are consumed when compared with conventional method. Improvements/ Applications: By investigating the various Sutras in Vedic mathematics, it has been observed that speed is increased and layout area is minimized.
