Digital bimodal function: An ultra-low energy security primitive
Teng Xu, James B. Wendt, Miodrag Potkonjak · 2013
We have developed a new security hardware primitive named digital bimodal function (DBF) that enables ultra low energy security protocols. DBF allows the computation of legitimate communicating sides to be compact and low-energy while it requires any attacker exponential computational effort and energy expense. Our new approach is competitive with the energy efficiency of traditional security key cryptographic security technique (e.g., AES) while more than three orders of magnitude more energy efficient than RSA. The implementation is demonstrated using the Xilinx FPGA platform.
