IP-based Wireless Sensor Networks (IP-based WSNs) combine IPv6 technology with WSNs to create a global sensor network infrastructure. However, wireless radio access and Internet connectivity make end-to-end security urgently needed by security critical WSN applications. Transport Layer Security (TLS) is considered as a suitable solution to ensure such security. However, the certificate-based mechanism...
It is worth noting that securing group communication in Wireless Sensor Networks (WSNs) has recently been extensively investigated. Although many works have addressed this problem, they have considered the concept of grouping differently. In this paper, we consider a group as being a set of nodes sensing the same type of data and we alternatively propose an efficient secure group communication scheme...
Security is a challenging issue in Wireless Sensor Networks (WSNs) due to the dual impact of their inherent constraints and their operation in open and harsh environments. The problem of securing a WSN becomes even more complex when considering group communications. In this paper, we address this problem and propose a new security mechanism for group communications in cluster-tree WSNs. We define...
Key management is an important cryptographic primitive upon which other security services are built. Most of the existent pairwise key management protocols consider homogenous ad hoc sensor networks. However, recent researches have demonstrated the limitation of this architecture in terms of performance and scalability. Therefore, this paper focuses on proposing a pairwise key management protocol...
Key management in wireless sensor networks is still a challenging problem. Most existing research considers symmetric cryptosystems to achieve key agreement assuming homogenous network architecture. However, these solutions suffer from performance bottleneck and poor scalability. Recently, deployed sensor network systems are increasingly following heterogeneous designs. In this paper, we propose a...
Wireless sensor networks (WSN) are the subject of widespread deployment in commercial and military environments that call for security. Since sensor networks pose unique challenges, traditional security techniques used in traditional networks cannot be directly applied. A previous work defines TinySec, a link layer security protocol for TinyOS to provide integrity and confidentiality of messages for...
