In this paper, we consider user authentication (UA) for wireless sensor networks. UA is a
fundamental issue in designing dependable and secure systems. Imagine that a wireless …

Over the last few years, many researchers have paid a lot of attention to the user
authentication problem. However, to date, there has been relatively little research suited for …

One of the most commonly used two-factor user authentication mechanisms nowadays is
based on smart-card and password. A scheme of this type is called a smart-card-based …

Wireless sensor networks (WSNs) are considered due to the ubiquitous nature, ease of
deployment, and wide range of possible applications. WSNs can be deployed in unattended …

Wireless sensor networks (WSNs) are getting popular for their deployment in unattended
environments, where a registered user can log in to the network and access data collected …

In this paper, we propose a new user authentication (UA) scheme based on one-time
password (OTP) protocol using smart cards for home networks. The proposed scheme is to …

Wireless sensor networks (WSNs) are vulnerable to security attacks due to their deployment
and resource constraints. Considering that most large-scale WSNs follow a two-tiered …

Owing to the ubiquitous nature, ease of deployment, and wide range of potential
applications, wireless sensor networks (WSNs) have received a lot of attention recently …

Abstract In 2004, Wu-Chieu proposed improvements to their original authentication scheme
in order to strengthen it to withstand impersonation attacks. In 2005, Lee-Lin-Chang …

Access control is a critical security service in Wire-less Sensor Networks (WSNs). To prevent
malicious nodes from joining the sensor network, access control is required. On one hand …
