Secure Logistic Regression for Vertical Federated Learning

He, Daojing (author), Du, Runmeng (author), Zhu, Shanshan (author), Zhang, Min (author), Liang, K. (author), Chan, Sammy (author)

Data island effectively blocks the practical application of machine learning. To meet this challenge, a new framework known as federated learning was created. It allows model training on a large amount of scattered data owned by different data providers. This article presents a parallel solution for computing logistic regression based on...

Biases in security risk management: Do security professionals follow prospect theory in their decisions?

de Wit, J.J. (author), Pieters, Wolter (author), Jansen, S.J.T. (author), van Gelder, P.H.A.J.M. (author)

Security professionals play a decisive role in security risk decision making, with important implications for security in organisations and society. Because of this subjective input in security understanding possible biases in this process is paramount. In this paper, well known biases as observed and described in prospect theory are studied in...

Identifying common grounds for safety and security research: a comparative scientometric analysis focusing on development patterns, similarities, and differences

Li, Jie (author), Goerlandt, Floris (author), van Nunen, K.L.L. (author), Reniers, G.L.L.M.E. (author)

Safety and security are often considered in complimentary or opposing terms. Discussions on their conceptual meaning have been put forward, and calls for an increased integration of these domains have been made. Nevertheless, there is currently no high-level empirical comparison of the development and contents of these research domains. In this...

A Control Method for Converter-interfaced Sources to Improve Operation of Directional Protection Elements

Yang, Zhe (author), Liu, Zhou (author), Zhang, Qi (author), Chen, Zhe (author), de Jesus Chavez, Jose (author), Popov, M. (author)

The traditional fault control strategy of converter-interfaced renewable energy sources (CIRESs) may bring about a lower sensitivity level or misoperation of fault component-based directional elements. To overcome this problem, a new control scheme is proposed to adjust sequence impedance angles of CIRESs by computing suitable current...

Anonymous and Verifiable Reputation System for E-commerce Platforms based on Blockchain

Li, Meng (author), Zhu, Liehuang (author), Zhang, Zijian (author), Lal, C. (author), Conti, M. (author), Alazab, Mamoun (author)

E-commerce platforms incorporate reputation systems that allow customers to rate suppliers following financial transactions. Existing reputation systems cannot defend the centralized server against arbitrarily tampering with the supplier’s reputation. Furthermore, they do not offer reputation access across platforms. Rates are faced with privacy...

On McEliece-Type Cryptosystems Using Self-Dual Codes With Large Minimum Weight

Mariot, L. (author), Picek, S. (author), R Yorgova, R.A. (author)

One of the Round 3 Finalists in the NIST post-quantum cryptography call is the Classic McEliece cryptosystem. Although it is one of the most secure cryptosystems, the large size of its public key remains a practical limitation. In this work, we propose a McEliece-type cryptosystem using large minimum distance error-correcting codes derived from...

Using the combined LADM-IndoorGML model to support building evacuation

Alattas, A.F.M. (author), van Oosterom, P.J.M. (author), Zlatanova, S. (author), Hoeneveld, D. (author), Verbree, E. (author)

During an incident, many people that are located in indoor environments require to follow emergency evacuation procedures. The ‘emergency evacuation’ term has been defined as ‘a critical movement of people from a dangerous area due to the risk or an incident of a tragic event’ (Bonabeau, 2002). An emergency evacuation could be needed in a...

Investigating the effect of security and privacy on IoT device purchase behaviour

Ho-Sam-Sooi, Nick (author), Pieters, W. (author), Kroesen, M. (author)

Given the significant privacy and security risks of Internet-of-Things (IoT) devices, it seems desirable to nudge consumers towards buying more secure devices and taking privacy into account in the purchase decision. In order to support this goal, this study examines the effect of security and privacy on IoT device purchase behaviour and...

Bayesian network model to distinguish between intentional attacks and accidental technical failures: a case study of floodgates

Chockalingam, S. (author), Pieters, W. (author), Teixeira, André (author), van Gelder, P.H.A.J.M. (author)

Water management infrastructures such as floodgates are critical and increasingly operated by Industrial Control Systems (ICS). These systems are becoming more connected to the internet, either directly or through the corporate networks. This makes them vulnerable to cyber-attacks. Abnormal behaviour in floodgates operated by ICS could be caused...

Practical Threshold Multi-Factor Authentication

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...
