Most of these fields can be anonymized in multiple ways providing trade-offs between security and utility. This is the first tool the authors are aware of that supports many levels of anonymization and is the only NetFlow anonymizer of which we are aware ¿ besides a previous, less advanced tool they developed.

As an important component to achieve Internet QoS, explicit signaling schemes for resource reservation have been proposed, which deal with admission, installation and refreshment of QoS reservation state information. To be useful, any QoS signaling protocol should provide a capability for authentication and authorization of the QoS requests, especially in environments where the end points are not trusted by the network nodes. However, existing protocols for QoS signaling encounter a number of authentication and authorization issues, which limit their application scenarios. The advent of NSIS QoS Signaling Layer Protocol (QoS-NSLP) offers the prospect to overcome some of these issues. After describing the overall design of QoS-NSLP, we present an approach to support advanced authentication and authorization capabilities by using the Extensible Authentication Protocol (EAP). In comparison with existing approaches, this approach, combined with the support for effective interaction with the Authentication, Authorization and Accounting (AAA) infrastructure, provides flexible and extensible authentication and authorization methods for the QoS signaling.","PeriodicalId":382662,"journal":{"name":"Workshop of the 1st International Conference on Security and Privacy for Emerging Areas in Communication Networks, 2005.","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127495083","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}

There is no hierarchy within the network, all nodes being given equal authority. No channel to nodes outside of the peer network is assumed to exist. In this untraditional environment we must provide traditional security properties and assure fairness in order to enable the secure, collaborative success of the network. One solution is to form a Trusted Domain, and exclude perceived dishonest and unfair members. Such solutions have previously been intolerant of masquerading, and have suffered from a lack of precise control over the allocation and exercise of privileges within the Trusted Domain. We introduce a model based on the work of Yang et. al. 2002 and Narasimha et. al. 2003 that provides granular control over privileges, and guards against masquerading. Continued good behavior is rewarded by an escalation of privileges, while requiring an increased commitment of resources. Bad behavior results in expulsion from the Trusted Domain. In colluding with malicious nodes, well behaved nodes risk losing privileges gained over time; collusion is thereby discouraged.","PeriodicalId":382662,"journal":{"name":"Workshop of the 1st International Conference on Security and Privacy for Emerging Areas in Communication Networks, 2005.","volume":"26 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133002703","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}

The infrastructure-less nature of MANETs renders trust establishment a rather complex issue. Many solutions using public key cryptography and digital certificates have been proposed in this direction. However, the problem of certificate revocation and certificate status information distribution in MANETs has not yet been fully addressed. ADOPT (Ad-hoc Distributed OCSP for Trust) proposes the deployment of a lightweight, distributed, on-demand scheme based on cached OCSP responses, which can efficiently provide up-to-date certificate status information. As accurate and current revocation information is critical for any application based on public key certificates, ADOPT's caching mechanism should ensure that cached responses are updated regularly. This paper discusses caching issues and time parameters concerning ADOPT and proposes various alternatives that fit into different scenarios.","PeriodicalId":382662,"journal":{"name":"Workshop of the 1st International Conference on Security and Privacy for Emerging Areas in Communication Networks, 2005.","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115586458","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}

Middleware systems have started to appear that aim at facilitating coordination among these devices, without the user even thinking about it, thus receding technology into the background. However, faced with overwhelming choice, additional support is required for applications to decide who can be trusted among this plethora of interacting peers. In this paper we propose a coordination model that exploits trust groups in order to promote safe interactions in the ubiquitous environment. Trust groups are asymmetric, that is, each device has its own view of the groups it belongs to, and long-lived, that is, their lifetime spans an extended period of time, despite group membership being dynamically handled. The dynamics of trust group creation, evolution and termination are described, based on the history of interactions of the device and on the ontology used to encode the context of trust. The programmer efforts required to reason about trust groups when coordinating mobile ad-hoc systems are discussed.","PeriodicalId":382662,"journal":{"name":"Workshop of the 1st International Conference on Security and Privacy for Emerging Areas in Communication Networks, 2005.","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124822405","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}

From the view point of preserving personal privacy, the simplest approach would be for users not to reveal any kind of private information at any time while keeping the number of available services unrestricted. Meanwhile, from the service provider's point of view, though this has been not clearly stated so far, their service logics should also be hidden from others because those logics may leak their know-how. This paper presents an ubiquitous service provisioning mechanism that gives more opportunities for users to get available services while preserving the secrecy of users' and providers' sensitive information. The basic idea of this mechanism is to share service execution procedures between the service provider and the user by exchanging converted service logic described in the form of Bayesian decision networks. This paper describes the proposed mechanism and the conversion algorithm for the Bayesian networks, and details the system architecture and implementation.","PeriodicalId":382662,"journal":{"name":"Workshop of the 1st International Conference on Security and Privacy for Emerging Areas in Communication Networks, 2005.","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129267799","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}

Ylitalo, Yki Kortesniemi","doi":"10.1109/SECCMW.2005.1588297","DOIUrl":"https://doi.org/10.1109/SECCMW.2005.1588297","url":null,"abstract":"In online communities, the users typically do not meet personally, and, thus, they have to estimate the trustwor- thiness of the other parties using other means. To assist these estimations, various reputation systems have been developed. But collecting the required reputation information, which, essentially, is information about the user's past, also creates privacy con- cerns. In this paper, we examine how the distribution of reputation management using P2P networks deals with the privacy concerns of processing reputation information. We analyze the distributed reputation management from three angles: how the requirements of fair use practices should be reflected on the system design, what classes of information is leaked and, finally, how to manage the risks related to the social and technical issues. I. INTRODUCTION In online communities, people are typically strangers to each other and do not meet face to face. Consequently, estimating the trustworthiness of the other parties is more difficult than in every day life. To assist users in their trust decisions and to reduce the related risks, various reputation systems are being developed. These systems collect reputation information about the the users' past behavior, and have a mechanism to provide trustworthiness estimates based on the information. Characteristically, many of the current online communities manage the reputation information in a centralized manner. One of the most analyzed examples is the eBay's feedback forum (12). In this type of a centralized solution, one benefit is that the trusted third party (in this case: eBay) can play an important role in trust evaluations. In contrast, fully distributed peer-to-peer (P2P) networks have no centralized trusted third parties and the actual interactions happen directly between the peers. The peers, e.g., provide storage capacity to the community and they have to be able to evaluate other peers' trustworthiness on their own. Although the reputation information is useful in trustwor- thiness estimation (33), (23), collecting this information also presents privacy problems. In reputation management, the privacy problems arise when large amounts of the information is easily available and the user can be identified. In particu- lar, the identifiable information enables undesired tracing of the user's past behavior and preferences. And these threats increase along with the current trend of boosting data storage and processing capacity, which allows the possible malicious peers more capacity for monitoring others. In this paper, we examine how the decentralization of reputation management in P2P networks deals with the privacy concerns of processing reputation information. Fundamentally, the reputation information itself has to be public at least within the target community to be of any use. This means that the users, who have agreed to being evaluated by the reputation system, have also willingly given up some of their privacy.
