Border Gateway Protocol (BGP) is the de facto inter-domain routing protocol. There have been many incidents of IP prefix hijacking by BGP protocol in the Internet. Attacks may hijack victim's address space to disrupt network services or perpetrate malicious activities such as spamming and DoS attacks without disclosing identity. The relation on prefix hijacking and the Internet hierarchy is presented in this paper. The Internet is classified into three hierarchies based on the power-law and commercial relations of autonomous systems. The relation of network topology and prefix hijacking influence is presented for all sorts of hijacking events in different layers. The result shows that the hierarchical nature of network influences the prefix hijacking greatly. © 2012 IEEE.

While many process mining algorithms have been proposed recently, there exists no widely-accepted benchmark to evaluate these process mining algorithms. As a result, it can be difficult to compare different process mining algorithms especially over different application domains. This paper presents our attempt in building such a benchmark by empirically evaluating process mining algorithms using reference models, in which the quality of a discovered model is measured by the behavioral and structural similarities with its reference model. In addition to artificial reference models extracted from academic papers and SAP suites, real-life processes from a major boiler manufacturer in China are added into the benchmark. © 2012 Authors.

In response to Internet emergencies, Internet resiliency is investigated directly through an autonomous system (AS) level graph inferred from policy-compliant BGP paths or/and traceroute paths. Due to policy-driven inter-domain routing, the physical connectivity does not necessarily imply network reachability in the AS-level graph, i.e., many physical paths are not visible by the inter-domain routing protocol for connectivity recovery during Internet outages. We call the invisible connectivity at the routing layer, which can be quickly restored for recovering routing failures by simple configurations, as the potential routing diversities. In this paper, we evaluate two kinds of potential routing diversities, which are recognized as Internet eXchange Points (IXPs) participant reconnection and peering policy relaxation. Using the most complete dataset containing AS-level map and IXP participants that we can achieve, we successfully evaluate the ability of potential routing diversity for routing recovery during different kinds of Internet emergencies. Encouragingly, our experimental results show that 40% to 80% of the interrupted network pairs can be recovered on average beyond policy-compliant paths, with rich path diversities and a little traffic shifts. Thus, this paper implies that the potential routing diversities are promising venues to address Internet failures. © 2004-2012 IEEE.

In this paper, we investigate the problem of controlling node sleep intervals so as to achieve the min-max energy fairness in asynchronous duty-cycling sensor networks. We propose a mathematical model to describe the energy efficiency of such networks and observe that traditional sleep interval setting strategy, i.e., operating sensor nodes with identical sleep intervals, or intuitive control heuristics, i.e., greedily increasing sleep intervals of sensor nodes with high energy consumption rates, hardly perform well in practice. There is an urgent need to develop an efficient sleep interval control strategy for achieving fair and high energy efficiency. To this end, we theoretically formulate the Sleep Interval Control (SIC) problem and find it a convex optimization problem. By utilizing the convex property, we decompose the original problem and propose a distributed algorithm, called GDSIC. In GDSIC, sensor nodes can tune sleep intervals through a local information exchange such that the maximum energy consumption rate in the network approaches to be minimized. The algorithm is self-adjustable to the traffic load variance and is able to serve as a unified framework for a variety of asynchronous duty-cycling MAC protocols. We implement our approach in a prototype system and test its feasibility and applicability on a 50-node testbed. We further conduct extensive trace-driven simulations to examine the efficiency and scalability of our algorithm with various settings. © 2012 IEEE.

The ability to efficiently retrieve data in their encrypted form is important for the cloud to become a truly secure and practical data sharing platform. Although this field has attracted tremendous research attention in the past a few years, most existing solutions do not support efficient searches with complex query conditions. Also, there has been little work to explore various comparison methods to specify complex query conditions. In this paper, we propose a framework of multi-keyword secure data retrieval to meet the needs of secure data retrieval with complex query support by leveraging recent development in attribute-based encryptions. Moreover, we propose a novel cryptographic comparison method based on forward and backward deviation functions (FDF/BDF). This method supports dual range comparisons and tree-oriented keyword search, as well as almost constant complexity for large size of integer range. We also provide several authentication mechanisms for preventing unpermitted access and verifying validity of protocol output. We implement a prototype system and our experimental results demonstrate its efficiency for practical usage. © 2012 IEEE.

Workflow testing is an important method of workflow analysis in design time. A challenging problem with trace-oriented test data generation in particular and trace-based workflow analysis in general is the existence of infeasible traces for which there is no input data for them to be executed. In this paper we build on the theory of workflow nets and introduce workflow nets where transitions have conditions associated with them. We then demonstrate that we can determine which execution traces, that are possible according to the control-flow dependencies, are actually possible taking the data perspective into account. This way we are able to more accurately determine in design time the infeasible traces caused by the correlation between transition conditions along this trace. Finally, we provide a solution to automatically detecting the shortest infeasible trace.
