Wang, Ruizhi (author), Liang, Yansong (author), Du, S. (author)An ultra-low-startup-voltage thermoelectric energy harvesting system assisted by a piezoelectric generator (PEG) is presented in this paper. When the energy harvesting system is implemented in a place where there is mechanical vibration, the associated PEG can generate a stable clock signal and drive the boost converter to start from the cold...conference paper 2022

(author), Han, Daoyang (author), Liu, Kun (author), Li, Mingliang (author), Liang, Yi (author), Yao, Meng (author), Wang, Hailong (author), Zhang, Rui (author), Shao, Gang (author)Temperature sensors that can operate in high-temperature and harsh environments are highly desired. However, this is a great challenge for sensing materials to operate under extreme working conditions because of oxidation and/or corrosion at high temperature. In this study, polymer-derived SiAlCN ceramics were prepared as sensing materials to...journal article 2022

Xie, Jiahong (author), Cheng, Haibo (author), Zhu, Rong (author), Wang, Ping (author), Liang, K. (author)To date there are few researches on the semantic information of passwords, which leaves a gap preventing us from fully understanding the passwords characteristic and security. We propose a new password probability model for semantic information based on Markov Chain with both generalization and accuracy, called WordMarkov, that can capture the...conference paper 2022

Xu, J. (author), Wang, R. (author), Koffas, S. (author), Liang, K. (author), Picek, S. (author)Graph Neural Networks (GNNs) are a class of deep learning-based methods for processing graph domain information. GNNs have recently become a widely used graph analysis method due to their superior ability to learn representations for complex graph data. Due to privacy concerns and regulation restrictions, centralized GNNs can be difficult to...conference paper 2022

Wang, Xingkai (author), Cao, Zhenfu (author), LIU, Z. (author), Liang, K. (author)Gordon et al. (TCC 2015) systematically studied the security of Multi-client Verifiable Computation (MVC), in which a set of computationally-weak clients outsource the computation of a general function f over their private inputs to an untrusted server. They introduced the universally composable (UC) security of MVC and proposed a scheme...conference paper 2022

Zheng, Yubo (author), Xu, Peng (author), Wang, Wei (author), Chen, Tianyang (author), Susilo, Willy (author), Liang, K. (author), Jin, Hai (author)Many practical secure systems have been designed to prevent real-world attacks via maximizing the attacking cost so as to reduce attack intentions. Inspired by this philosophy, we propose a new concept named delay encryption with keyword search (DEKS) to resist the notorious keyword guessing attack (KGA), in the context of secure cloud-based...conference paper 2022

He, Xiaoxi (author), Cheng, Haibo (author), Xie, Jiahong (author), Wang, Ping (author), Liang, K. (author)Passwords have been widely used in online authentication, and they form the front line that protects our data security and privacy. But the security of password may be easily harmed by insecure password generator. Massive reports state that users are always keen to generate new passwords by reusing or fine-tuning old secrets. Once an old...conference paper 2022

Ma, Yunjian (author), Liang, Hongjing (author), Zhao, Zexin (author), Wu, Bin (author), Lan, Dongming (author), Hollmann, F. (author), Wang, Yonghua (author)Unspecific peroxygenases (UPOs, EC 1.11.2.1) are promising oxyfunctionalization catalysts because of their unique stereoselectivity. However, so far only a few UPOs have been reported. In this study, gene mining was used to identify a gene from Galerina marginata that coded for a novel UPO (GmaUPO). GmaUPO was expressed in Pichia pastoris X...journal article 2022

Tjiam, Kevin (author), Wang, R. (author), Chen, H. (author), Liang, K. (author)Smart contracts on Ethereum enable billions of dollars to be transacted in a decentralized, transparent and trustless environment. However, adversaries lie await in the Dark Forest, waiting to exploit any and all smart contract vulnerabilities in order to extract profits from unsuspecting victims in this new financial system. As the...conference paper 2021

Li, Wenting (author), Cheng, Haibo (author), Wang, Ping (author), Liang, K. (author)Multi-factor authentication (MFA) has been widely used to safeguard high-value assets. Unlike single-factor authentication (e.g., password-only login), t-factor authentication (tFA) requires a user always to carry and present t specified factors so as to strengthen the security of login. Nevertheless, this may restrict user experience in...journal article 2021

Liang, Danni (author), de Jong, Martin (author), Schraven, D.F.J. (author), Wang, Lili (author)Many local governments engaging in sustainable urban development also have a growing interest in becoming inclusive too, brand themselves as such and develop policies to become inclusive cities. However, knowing what exactly this entails and how it can be achieved is not always quite straightforward and requires thorough theoretical and...journal article 2021

Liang, Hongqin (author), Liu, Pengfei (author), Wang, Tianlong (author), Wang, Haoyu (author), Zhang, Kailong (author), Cao, Yunqiang (author), An, Dong (author)For a heavy-haul locomotive within a wheel repairing period, wheel polygonal wear with different operating mileages is obtained by field testing. The test results show that the maximum radial runout of the wheel can increase to 0.87 mm and accompany with the typical damage of wheel tread shelling. Taking the wheel polygons as input excitation...journal article 2020
