Cloud computing is an emerging computing paradigm in which resources of the computing infrastructure are provided as services over the Internet. As promising as it is, this paradigm also brings forth many new challenges for data security and access control when users outsource sensitive data for sharing on cloud servers, which are not within the same trusted domain as data owners. To keep sensitive...
Recent advances in distributed in-network data storage and access control have led to active research in efficient and robust data management in wireless sensor networks (WSNs). Although numerous schemes have been proposed this far, most of them do not provide enough attention towards exploiting user hierarchy and sensor heterogeneity, which is quite a practical issue especially when deploying WSNs...
Access control in content distribution networks (CDNs) is a long-standing problem and has attracted extensive research. Traditional centralized access control approaches, such as reference monitor based approach, do not suit for CDNs as such networks are of large scale and geographically distributed in nature. Current CDNs usually resort to cryptographic-based distributed approaches for better fulfilling...
Recently, multi-hop wireless mesh networks (WMNs) have attracted increasing attention and deployment as a low-cost approach to provide broadband Internet access at metropolitan scale. Security and privacy issues are of most concern in pushing the success of WMNs for their wide deployment and for supporting service-oriented applications. Despite the necessity, limited security research has been conducted...
