Attribute-based encryption (ABE) has opened up a popular research topic in cryptography over the past few years. It can be used in various circumstances, as it provides a flexible way to conduct fine-grained data access control. Despite its great advantages in data access control, current ABE based access control system cannot satisfy the requirement well when the system judges the access behavior...
While more and more real-time applications are expected in wireless mesh networks (WMNs), Quality of Service (QoS) provision is of foremost importance in order to support such real-time applications. In this paper, we proposed QRBC (QoS Routing protocol with Bandwidth Consideration), a protocol using a bandwidth guaranteed routing metric towards enhancing QoS support for the real-time applications...
Location information has been found useful in the design of key predistribution schemes in wireless sensor networks (WSNs). In this paper, a novel key management scheme based on location is proposed to enhance the security of the wireless sensor networks. We get the idea from the previous location-based key (LBK) scheme but here the location of a sensor node is described by its neighbors' logical...
The key issue for WSN (wireless sensor network) is designing viable security mechanisms for the protection of confidentiality, integrity and authentication to prevent malicious attacks, but with nodespsila limited capabilities. Recently, Cheng proposed an efficient key distribution mechanism for large scale wireless sensor network based on hierarchical topology. In this paper, we show that Chengpsilas...
