FPGA Implementation of Elliptic-Curve Diffie Hellman Protocol

This paper presents an efficient crypto processor architecture for key agreement using ECDH (Elliptic-curve Diffie Hellman) protocol over . The composition of our key-agreement is expressed in consisting the following: (i) Elliptic-curve Point Multiplication public generation (DESIGN-I) and (ii) integration DESIGN-I with two additional routing multiplexers a controller shared (DESIGN-II). arithmetic operators used DESIGN-II contain adder, squarer, multiplier inversion. A simple shift add multiplication method employed to retain lower hardware resources. Moreover, essential inversion operation operated Itoh-Tsujii algorithm similar resources squarer units. proposed implemented Verilog HDL. implementation results are given on Xilinx Virtex-7 FPGA (field-programmable gate array) device. For , utilized Slices 3983 4037, time compute one secret 553.7 μs 1170.7 (iii) consumed power 29 μW 57 μW. Consequently, achieved area optimized reduced show that suitable alternative (to generate secret) applications require low consumption.
