In principle any network that has been engineered without taking into account the presence of unwanted traffic might experience troubles during periods of massive exposure to it, e.g. large-scale infections. A concrete example was provided by the spreading of Code-Red-II in 2001, which caused several routers crashes worldwide. Similar events might take place in 3G networks as well, with further potential complications due to the functional complexity and the scarcity of radio resources. In this explorative paper, we show that unwanted traffic is present also in GPRS/UMTS, mainly due to the widespread use of 3G connect cards for laptops. Based on a mixture of real-world measurements and theoretical speculations, we investigate the potential impact of such traffic onto the underlying network. We show that under certain hypothetical network configuration settings unwanted traffic, and specifically scanning traffic from infected mobile stations, can cause large-scale wastage of logical resources, and in extreme cases starvation. We urge the research community and network operators to consider the issue of 3G robustness to unwanted traffic as a prominent research area. The goal of this paper is to trigger interest and at the same time move a first pioneering step in this direction","PeriodicalId":174651,"journal":{"name":"Second International Workshop on Security, Privacy and Trust in Pervasive and Ubiquitous Computing (SecPerU'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129275419","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This information might be unclassified, such as environmental data, or private, such as the location of an important asset. In the latter case, security mechanisms might be essential to ensure the confidentiality of the location of the information source. Such mechanisms might exploit light cryptographic systems, such us elliptic curve, to authenticate and cipher the information that is relayed towards the sink. On the other hand, the static configuration of WSNs might simplify the apocalypses of the information source. An eavesdropper might use reverse packet-routing engineering to expose the location of the sensor that captured and reported the phenomenon. To deal with this issue, we have introduced a novel approach, called iHIDE - information hiding in distributing environments, to enable source-location privacy in WSNs. iHIDE adopts a non-geographical, overlay routing method for packet delivery. This paper introduces the architecture, and assesses its performance through simulation experiments, providing comparisons with relative approaches","PeriodicalId":174651,"journal":{"name":"Second International Workshop on Security, Privacy and Trust in Pervasive and Ubiquitous Computing (SecPerU'06)","volume":"283 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116092182","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the fact that most information sources are visited only occasionally by the same client, and thus, direct own experience rarely suffices. The accuracy of trust inference for unknown information sources may considerably deteriorate due to \"noise\" or to the intervention of malicious nodes producing and propagating untrustworthy referrals. In this paper, we describe an innovative approach for trust inference in the semantic Web and in trust networks in general, referred to as FACiLE (faith assessment combining last edges). Unlike all other approaches, FACilE infers a trust value for an information source from a proper combination of only the direct trust values of its neighbours. We evaluate the efficiency of our approach by means of a series of simulation experiments run for a wide variety of mixes of sources of untrustworthy information. FACiLE outperforms other trust-inference approach in the most interesting cases of population mixes","PeriodicalId":174651,"journal":{"name":"Second International Workshop on Security, Privacy and Trust in Pervasive and Ubiquitous Computing (SecPerU'06)","volume":"303 11","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113959044","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
