A Compressive Integrity Auditing Protocol for Secure Cloud Storage

With the widespread application of cloud storage, ensuring the integrity of user outsourced data catches more and more attention. To remotely check the integrity of cloud storage, plenty of protocols have been proposed, implemented by checking the equation constructed by the aggregated blocks, tags, and indices. However, the verifier only has the knowledge of the indices of the audited blocks and tags, which thus requires the cloud to store both data blocks and tags for integrity verification. In this article, we present a compressive secure cloud storage protocol inspired by Goldreich-Goldwasser-Halevi (GGH) cryptosystem. Since the aggregated blocks can be reconstructed from the aggregated tags without the help of data indices, the cloud can only store data tags for providing the verifiable integrity proof. In this way, communication and storage costs can be hugely reduced and user private information can be hidden from the cloud. Furthermore, the proposed protocol only contains a few basic algebraic operations, making it highly efficient. We also provide formal security proof of the proposed protocol regarding forge, replay and replace attacks. In addition, we explore a new technique to support data dynamics. Furthermore, we establish a generic framework of compressive secure cloud storage protocols. Finally, we provide the theoretical analysis and experimental results, which further validate the effectiveness of the proposed protocol.

Transition from Legacy to Connectivity Solution for Infrastructure Control of Smart Municipal Systems

Abstract Collaboration between heterogeneous systems and architectures is not an easy problem in the automation domain. By now, utilities and suppliers encounter real problems due to underestimated costs of technical solutions, frustration in selecting technical solutions relevant for local needs, and incompatibilities between a plenty of protocols and appropriate solutions. The paper presents research on creation of architecture of smart municipal systems in a local cloud of services that apply SOA and IoT approaches. The authors of the paper have developed a broker that applies orchestration services and resides on a gateway, which provides adapter and protocol translation functions, as well as applies a tool for wiring together hardware devices, APIs and online services.

An Efficient Backbone Based Quick Link Failure Recovery Multicast Routing Protocol

Summary MANET is a set of independent mobile devices which communicate through constrained wireless links over a relative bandwidth. Due to the mobility of devices, the topology of the network may change rapidly and unpredictably over time, making multicast routing and route maintenance a very crucial task. Plenty of protocols have been proposed for the construction of virtual backbone, but they have limitations in terms of control overhead, delay, throughput, energy consumption and mobility. As a part of multicast routing, virtual backbone construction has been proposed and classified into three different techniques: tree-based virtual backbone, cluster-based virtual backbone and dominating set-based virtual backbone. Upon this classification, plenty of protocols are available, and each protocol has some limitations in terms of control overhead, delay, throughput, energy consumption and mobility. Besides this, no existing backbone protocol has the scope of recovery of link failures. In order to overcome the limitations of existing protocols, our proposed protocol An Efficient Backbone Based Quick Link Failure Recovery Multicast Routing Protocol, it is a four phase protocol: Group Formation, Backbone Construction, On-demand Route Discovery and Route Maintenance. The main aim of the proposed protocol is to construct an efficient robust backbone to overcome the limitations of existing protocols and to provide a mechanism for the quick recovery of link failures by generating an alternate path from the point of failure to the destination, which can be adoptable in any sort of environment.

An Adaptive Key Management Framework for the Wireless Mesh and Sensor Networks

Wireless sensor networks (WSNs) and wireless mesh networks (WMNs) are popular research subjects. The interconnection of both network types enables next-generation applications and creates new optimization opportunities. Currently, plenty of protocols are available on the security of either wireless sensor networks or wireless mesh networks, an investigation in peer work underpins the fact that neither of these protocols is adapt to the interconnection of these network types. The internal cause relies on the fact that they differ in terms of complexity, scalability and network abstraction level. Therefore, in this article, we propose a unified security framework with three key management protocols, MPKM, MGKM, and TKM which are able to provide basic functionalities on the simplest devices and advanced functionalities on high performance nodes. We perform a detailed performance evaluation on our protocols against some important metrics such as scalability, key connectivity and compromise resilience, and we also compare our solution to the current keying protocols for WSNs and WMNs.
