This paper examines the performance of a periodic rekeying technique for the key management of groups that exhibit bursty behaviour. Experimental results demonstrate that this technique costs far fewer key generations than existing approaches, and is therefore more efficient in terms of computation. When the pre-processing of joining members can be performed during the rekeying period, this technique reduces the rekeying time at the end of the rekeying period to the lower bound","PeriodicalId":202819,"journal":{"name":"Fourth European Conference on Universal Multiservice Networks (ECUMN'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130877599","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}

Our method includes three components: feature extraction, feature discretization and key generation.

Then, in the feature discretization stage, a discretization process is introduced to generate a stable binary string from the fused feature vectors.

We design the E2E tunnel state model running on the packet data gateway (PDG) using the CAMEL concept, and introduce the mobility server to re-establish sessions with third party call control (SPCC). The mobility server is triggered to provide the terminal mobility service from the PDG by detecting the state transition of E2E tunnel state model that represents the occurrence of a handover. This mechanism can advance the time to re-establish sessions. That is, our approach can provide smaller handover delay than SIP mobility; moreover, it can handle mobility without additional support from the mobile host. In addition, the handover missing problem (messages lost) might happen when the MH moves under communication. With the help of the mobility server, the lost messages are re-sent, and the handover missing problem, including simultaneous movement, is therefore solved","PeriodicalId":202819,"journal":{"name":"Fourth European Conference on Universal Multiservice Networks (ECUMN'07)","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127397711","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 separate the publish and subscribe functions into different protocols as it is not necessary for a given device to support both. The publication protocol is designed for management systems in which nodes take readings from a sensor and transmit them to monitoring applications while the subscription protocol is for actuating systems in which the state of certain nodes is changed by control applications. The protocols use cross-layer optimization techniques for reducing transmissions within the messaging layer of the sensor-network. We show that the path characteristics of such network are highly variable leading to frequent topology changes motivating our description of the protocols which can function even over fluctuating network topologies. Finally, we use simulation to compare the actuation protocol with an epidemic approach, showing that our protocol is more efficient when the topics that the nodes are interested in are non-uniform","PeriodicalId":202819,"journal":{"name":"Fourth European Conference on Universal Multiservice Networks (ECUMN'07)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125237974","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}

As MANETs have limited resources, it is important to reduce the number of control packets which consume bandwidth. We propose a AODV-based protocol which uses a backbone network to reduce control packets. The destination location is given by GPS and transmitted to the source by the backbone network. Our routing algorithm limits the route search to zones smaller than those used by the original AODV (ad hoc on-demand distance vector) protocol, thus reducing the number of control packets. This routing algorithm represents a significant improvement of our previous work on AODV (D. Espes and Z. Mammeri, 2006).

If not targeted at the beginning, information system security became rapidly a key challenge for professionals and strong security solutions emerged on the market mainly for professionals. Internet security is thus today two-speed: pretty strong security for professionals or private individuals anxious to protect their computer equipments and no security for professionals or private individuals who can not afford security products and do no have sufficient technical expertise to set up cheap solutions by themselves. In this context, this paper targets the provision of a minimum security level within internet by defining a PKI solution based on LDAP and DNS (extended with DNSSEC).
