Dynamic current mode logic based flip‐flop design for robust and low‐power security integrated circuits
Jizhong Shen, Liang Geng, Fan Zhang · Electronics Letters · 2017
Side‐channel analysis (SCA) is a powerful technique to reveal the secrets using detectable physical leakages from logic elements, which brings severe security threats to modern circuits. To alleviate this problem, applying cell‐level countermeasure is usually a suitable solution, which is mainly implemented as dual‐rail precharge logic. Mace et al. has the proposed dynamic current mode logic (DyCML) scheme as a novel technology to resist SCA, whose power consumption is constant regardless of the data processed. However, the DyCML‐based sequential elements are still in blank field. So, we have implemented a novel flip‐flop compatible with DyCML, whose enhanced security has been proved by corresponding simulations.
