This work presents security solutions related to multi-sensor closed-loop artificial pancreas (AP) systems. The proposed AP system is built on a heterogeneous platform incorporating a smartphone, activity sensors, a glucose monitor, an insulin pump, a laptop hosting the multi-variable control algorithm and a cloud server. Developing a secure AP system is essential for mass adoption among diabetes...
Data aggregation is a significant issue for marine wireless sensor networks. However, marine sensors are always deployed far away from the security monitoring. Thus, the secure data aggregation for marine sensor networks emerges and attracts the researchers and engineers. Multi-signature enables the data aggregation with a single signature to authenticate the message under different signers. However,...
The heterogeneous Internet of things bridges together multiple devices with different capabilities, functionalities, configurations, platforms, varieties and multiple users with different roles advocating its ubiquity and thereby, exposing the security risks faced by devices and users. Security is paramount for the safe, reliable operations of IoT connected devices and it is the foundational enabler...
Wireless body area networks (WBANs) are expected to act as an important role in monitoring the health information and creating a highly reliable ubiquitous healthcare system. Since the data collected by the WBANs are used to diagnose and treat, only authorized users can access these data. Therefore, it is important to design an access control scheme that can authorize, authenticate, and revoke a user...
In Wireless Senor Networks the use of multiple encryption keys is adopted to provide resilience against compromised encryption keys. The keys are either pre distributed or generated post deployment. Key pre distribution causes redundancy and limits scalability and link establishment. Key generation via computation requires processor intensive operations and the network might still be prone to serious...
The anticipated proliferation of smart devices, the "Internet of Things" (IoT), is one of the motivations for some large-scale research efforts aiming to design a new Internet architecture. One such effort is Named-Data Networking (NDN) - a "future internet architecture" research project in the Information-Centric Networking (ICN) area that emphasizes efficient, scalable and secure...
In this paper, we study the problem of secure key management for smart grid. Since existing key management schemes are not suitable for deployment in smart grid, in this paper, we propose a novel key management scheme which combines symmetric key technique and elliptic curve public key technique. The symmetric key scheme is based on the Needham-Schroeder authentication protocol. We show that the known...
This paper describes the design, implementation and performance of a security and privacy framework for SenSearch, which is a sensor-based search and rescue system for people in emergency situation in wilderness areas. A key obstacle in a wide deployment of search and rescue systems such as SenSearch is vulnerability to users' security and privacy. Support for security and privacy for SenSearch has...
Wireless Sensor Networks (WSNs) is a very attractive technique to support Ubiquitous Pervasive Computing (UPC) due to many merits such as compact form, low-power, and potential low cost. However, the more the number of sensor node is increased, the more difficult the manager monitors WSNs individually. And faults of the sensing value are common due to the artificial attacker and the lack of physical...
This paper develops an authentication framework for heterogeneous wireless sensor networks. We introduce a novel concept, called k-security, in order to thwart the impact of false alerts emanating from malicious sensor nodes. The proposed technique relies on elliptic curve cryptography and threshold signature. The major novelty of our approach is that an intermediate verification of the alert messages...
Pervasive computing environment is viewed as an incorporated space comprised of mobile users, system services, system resources, and sensors embedded in physical environment. Users can access resources and obtain services anytime, anywhere. Trust is crucial to secure interaction among previously unknown principals. Traditional trust solutions normally depend on centralized trust certification authorities,...
While symmetric-key schemes are efficient in processing time for sensor networks, they generally require complicated key management, which may introduce large memory and communication overhead. On the contrary, public-key based schemes have simple and clean key management, but cost more computational time. The recent progress of elliptic curve cryptography (ECC) implementation on sensors motivates...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
Huge interest and demand on information superhighway have pressed various telecommunications research fronts and lead to a new form of future Internet consisting of wired and wireless segments where resource-constrained devices such as palm pilots and sensors may become integral parts of the Internet rather than access-only platforms. One of the key design problems is the security in such heterogeneous...
