Most of the currently proposed authorization frameworks do not provide scalable, manageable, effective, and efficient mechanisms to support distributed systems with many interacting services. The advent of IoT will further increase the need for scalable and manageable solutions able to face the potentially unbound number of sensors, actuators and related resources, services and subjects. This is even more relevant if we take into account that IoT environments can envisage not only a greater number of resources to manage, but also a substantial increase of the interaction dynamics. This paper presents a capability based access control system that enterprises, or even individuals, can use to manage their own access control processes to services and information. The proposed mechanism supports rights delegation and a more sophisticated access control customization. The proposed approach is being developed within the European FP7 IoT@Work project to manage access control for some of the project's services deployed in the shop floor.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129358860","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}

However, accurately inferring what is the cause of routing instability and where it originate is very hard. In this paper, we present a novel approach to locate the origin of routing instability by analyzing the relationship of the closed loops formed by intersecting the all the paths in path exploration and the length variation of the paths received in a single vantage point. Then we demonstrate our approach using BGP data obtained by simulations and show that the method is quite effective. Once there is path exploration when a routing event triggering BGP updates, this approach can precisely identify whether the event is a link failure and pinpoint the right place where the event exactly happens if so. Otherwise the approach can deduce the candidate set of locations to a small size.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116162763","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}

According to such perspective computing, storage and sensing become complementary aspects to be coordinated. In this way innovative and value-added services can be implemented by bridging Clouds with the Internet of Things. Heterogeneous resources can be aggregated and abstracted according to tailored thing-like semantics, thus enabling a Things as a Service paradigm, a way to build a \"Cloud of Things\" (CoT). This paper mainly focuses on the implementation of the underlying infrastructure at the basis of the CoT. An ad-hoc architecture and some preliminary background of this challenging view are provided and discussed, identifying guidelines and future directions.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"194 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121741469","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}

Though Cloud Computing is very popular, cloud security could delay its adoption. Security of the cloud must provide data confidentiality and protection of resources. Such architecture seems to be vulnerable when confronted to distributed attacks also known as large-scale coordinated attacks. In this paper, we study the impact of large-scale coordinated attacks on Cloud Computing and its current security solutions. We experiment the open-source IDS Snort and a commercialized firewall using distributed port scan. Our results show that these security solutions are not designed to detect distributed attacks. Indeed, an attacker who controls about 32 hosts can easily achieve a distributed port scan without being detected.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125862028","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}

One of main aspect that can ensure the success in this operation is the correct integration and harmonization of the human factor with all remaining factors of a security system.

In recent years, several anti-collision protocols have been proposed in order to address this problem. However, the evaluation of these approaches is often based on simple models that consider only direct collisions among two readers. Instead, more complex models capture the total signal power emitted by each reader and assume that the power of each signal decays as distance grows. In this paper, the main models of the two families are described, and a comparison is presented, in order to investigate their effectiveness for the study and the evaluation of reader-to-reader collision.","PeriodicalId":290976,"journal":{"name":"2012 Sixth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127715421","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}

A framework for cognitive networks is presented and a novel cognition loop which is more consistent with human cognition is proposed.

It has provable security based on the computational hardness assumption. More specifically, the security of QUAD depends on hardness of solving non-linear multivariate system us over a finite field, and it is known as an NP-Hard problem. However, QUAD is slower than other stream ciphers, and an efficient implementation, which has a reduced computational cost is required. In this paper, we propose an efficient implementation of computing multivariate polynomial systems for multivariate cryptography on GPU and evaluate efficiency of the proposal. GPU is considered to be a commodity parallel arithmetic unit. Moreover, we give an evaluation of our proposal.
