ECC coprocessor over a NIST prime field using fast partial Montgomery reduction

P Choi, MK Lee, DK Kim - … on Circuits and Systems I: Regular …, 2020 - ieeexplore.ieee.org
Montgomery reduction is a well-known optimization technique for modular reduction over
prime fields. However, it has rarely been used for national institute of standards and …

Architectural supports for block ciphers in a RISC CPU core by instruction overloading

P Choi, W Kong, JH Kim, MK Lee… - IEEE Transactions on …, 2021 - ieeexplore.ieee.org
We propose a novel computer architectural concept of instruction overloading to support
block ciphers. Instead of adding new instructions, we extend only the execution of some …

Lightweight ECC coprocessor with resistance against power analysis attacks over NIST prime fields

P Choi - IEEE Transactions on Circuits and Systems II: Express …, 2022 - ieeexplore.ieee.org
This brief proposes a compact and fast elliptic curve cryptography coprocessor using affine
coordinates. Although using affine coordinates requires compute-intensive modular …

A Single-ring-oscillator based True-random-numbergenerator with 3-edges Collapse

E Kim, JJ Kim - JOURNAL OF SEMICONDUCTOR TECHNOLOGY …, 2023 - dbpia.co.kr
This paper presents an all-digital ring oscillator (RO) based true random number generator
(TRNG) that harvests entropy as a jitter. The proposed TRNG constructs upon the collapsing …
