When securing such a network, it is important that we minimize the number of computationally expensive security operations without compromising on the security. This talk deals with the test-bed implementation of our end to end secure data aggregation algorithm. Unlike previous algorithms which required separate phases for secure aggregation and integrity verification, ours does not require an additional phase for verification. This saves energy by avoiding additional transmissions and computation overhead on the sensor nodes. We have implemented our secure data aggregation algorithms on mica2 motes. To sum up our objectives as follows: 1. An encryption algorithm for data confidentiality which will allow us to aggregate encrypted data in a wireless sensor network. 2. An aggregate digital signature algorithm to preserve data integrity which allows us to aggregate digital signatures. 3. An implementation of these algorithms which is efficient in computational and communicational aspects in energy constrained environments.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126128479","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 long-term research question is how best to support beneficial uses while preserving individual privacy. Presence systems are an emerging class of applications that support collaboration. These systems leverage pervasive sensors to estimate end-user location, activities, and available communication channels. Because such presence data are sensitive, to achieve wide-spread adoption, sharing models must reflect the privacy and sharing preferences of the users. To reflect users' collaborative relationships and sharing desires, we introduce CollaPSE security, in which an individual has full access to her own data, a third party processes the data without learning anything about the data values, and users higher up in the hierarchy learn only statistical information about the employees under them. We describe simple schemes that efficiently realize CollaPSE security for time series data. We implemented these protocols using readily available cryptographic functions, and integrated the protocols with FXPAL's myUnity presence system.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126843305","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}

We investigated scenarios in which users integrated their online interactions with offline activities. We found that Facebook heightened the visibility of social identities, but that these identities are multifaceted and dynamically modulated by context. We found that Facebook broadly facilitated offline activities from proposing and planning through to report and commenting. We found that people use Facebook features differentially as they maintain strong and weak ties. Finally we discussed how social identities, social engagements, and social ties are mutually reinforcing and cultivating with the affordances of Facebook.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125207025","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}

We propose a new principle for the design of such systems: the delegation of executable behavior. This principle leads to an alternative framework in which the operation environment, rather than XML messaging, is standardized. The operation environment can then execute remotely delegated behavior. Such delegation is achieved in three classes of web systems: dynamic script delegation systems, plug-in delegation systems, and ontology exchange systems. Examples of each class are presented here. An application of the proposed principle to use cases of web crawlers and software agents is discussed and an analysis of the advantages and disadvantages for the different types of system architectures is included. While the class of traditional web services is populated very well with existing systems, the three classes of executable behavior delegation systems are under-populated. However all the presented examples of executable behavior delegation systems have significant advantages over traditional web services. Thus it is expected that future trends in web system architectures will be seen as a migration from the class of traditional web services to the three classes of systems with executable behavior delegation.","PeriodicalId":426543,"journal":{"name":"2011 International Conference on Collaboration Technologies and Systems (CTS)","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131827753","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}

Recent abundance of sharing tool choices and disruption of practices makes for a lack of agreement and coherence in the use of information sharing tools. At work, email remains the primary way for sharing information, despite years of knowledge management research. We examine the design of a system for lightweight organizational sharing called Mail2Tag, which augments email by utilizing existing email sharing practices to help gather content, implicitly organize that content, and evolve both the shared content and the groups of people interested in that content.
