Sensor networks are composed of a large number of low power sensor devices. For secure communication among sensors, secret keys are required to be established between them. Considering the strict resource constraints of sensors, key infection has been proposed by Anderson, Chan, and Perrig. However, because the communication keys are broadcasted in plaintext in key infection, some of them may be eavesdropped...
Based on the simulation paradigm, Acs et al proposed a formal model tailored to the security analysis of on-demand source routing protocols in MANET, and a new routing protocol, called endairA, was proven secure in the model. We indicate the improper manipulations such as mergence of the adjacent adversarial nodes, the improper definition of secure route in the model, and the flaw in the proof for...
We consider the problem of group key agreement among n parties communicating over an insecure ad hoc network. Firstly, we analyze the state and the problem of existing group key management schemes, and then present a secure, efficient and contributory group key management scheme, which is based on elliptic curve cryptosystems (ECC). The security of our scheme relies on the hardness of elliptic curve...
Available WLAN Mesh network access protocols and trusted network connect protocols can not satisfy the performance and security requirements of WLAN Mesh networks in trusted environment. A provably secure trusted access protocol MN-TAP for the WLAN Mesh Networks is proposed. Such protocol will achieve authentication and key confirmation among the access requestor, policy enforcement point and policy...
Security and privacy of wireless sensor networks are key research issues recently. Most existing researches regarding wireless sensor network security consider homogenous sensor networks. To achieve better security and performance, we adopt a heterogeneous wireless sensor network (HWSN) model that consists of physically different types of sensor nodes. This paper presents a secure message distribution...
Sensor networks are resource-constrained, which makes developing efficient key distribution scheme a challenging problem. In general, many key distribution techniques are designed to address the trade-off between limited resources and security, no key distribution technique is ideal to all the scenarios where sensor networks are used. In this paper, we primarily focus on storage requirements of several...
