Self-synchronous circuit designs, SSFPGA and SSRSA for low voltage autonomous control and tamper resistivity

We have been working for asynchronous control with fine-grain pipeline circuits, namely, self-synchronous circuits. We have demonstrated self-synchronous FPGA (SS-FPGA) designs with autonomous gate-level power gating to reduce energy consumption at the energy minimum operating point. We have also demonstrated self-synchronous RSA crypt-engine (SS-RSA) to realize high throughput in nominal operating voltage and low energy in low operating voltage, without any information leakage against various tampering attacks such like SPA, DPA and HO-DPA.
