Protecting the environment from many threats has become a priority worldwide. The existing sensor technology enables the continuous monitoring of various parameters related to environment status, such as air quality and many others. In this paper we propose a secure architecture based on cellular networks to collect such sensors' information in real time. The cell phones can interact with the cellular...
The IP-based Internet of Things refers to the interconnection of smart devices in a Low-power and Lossy Network (LLN) with the Internet by means of protocols such as 6LoWPAN or CoAP. The mechanisms to protect the LLN from attacks from the Internet and provisioning of an end-to-end (E2E) secure connection are key requirements for functionalities ranging from network access to software updates. Interconnecting...
By enabling users to allocate computing resources on demand, cheaply, and in an elastic manner, Cloud Computing has made large computation resources available to small and medium size organizations. However, using the Cloud requires users to place their computations, data, or both in a shared data center own by an outsider. This sharing has raised many security concerns. Such concerns are much apparent...
A new project called the Server-Based Internet-Of-Things Architecture (SBIOTA) is introduced. The aim is to develop architectures, protocols, algorithms and services, based on a gateway server, which allow networked devices with extremely limited computation and communications capabilities to participate in the future Internet effectively, efficiently and securely. Key features are the use of a gateway...
In this paper, we propose a secure system model for interconnection between P2PSIP and IMS domains. The interworking solution is based on P2P-IMS GateWay (PIGW), which acts as a normal peer in P2PSIP network and a 3rd party IMS Application Server (AS) in IMS network. The security is achieved by implementing Chord Secure Proxy (CSP) and enhanced with subjective logic based trust model. We also implement...
Aiming at the security requirement of the Intranet that is different from Internet, an security architecture for Intranet is proposed. In physical layer and data link layer, based on network switch the intranet is divided into several parts separated from each other as required. In network layer, making use of the NAT gateway integrated in virtual server the intranet or its part is hidden to ensure...
In recent years, the agricultural information network construction has made a great progress in China. With the level of network openness improved, the probability of network attacked is increasing. So, it needs a higher demand for network stability and security. Through analyzing the status quo of agricultural information network security and network security defensive strategy architecture, this...
Wireless mesh network is emerging as a new generation of wireless network architecture, attracting much research on MAC, routing, application, etc. Widen applied in wide areas, there will produce massive data storage requirements. The paper presents a Hierarchical Storage System on wireless mesh network, with high availability, scalability, self-heal, self-organizing, load balanced. Key technologies...
A current trend in the web services community is to define coordination mechanisms to execute collaborative tasks involving multiple organizations. Following this tendency, this work presents a dependable (i.e., intrusion-tolerant) infrastructure for cooperative web services coordination that is based on the tuple space coordination model. This infrastructure provides decoupled communication and implements...
Fieldbus networks have significantly improved flexibility and management in classic building automation domains. However, the costs of such installations are still greatly affected by the commissioning efforts needed to bring them up and running. The dedicated cabling, initial engineering efforts and sophisticated binding and configuration tools often prevent home owners from investing in such networks...
