Server and Clients Node Capture Attacks

Abstract:

In this project, we addressed the mitigation of control channel jamming by malicious colluding

insiders and compromised system users as well as the identification of compromised users

without prior knowledge of the number of compromised users in the system. We mapped the

problem of control channel access that is robust to jamming by compromised users to the

problem of secure key establishment under node capture attacks. Based on the mapping, we

proposed a framework for control channel access schemes using random key assignment. We

proposed and evaluated metrics for resilience and delay which quantify the availability of control

messages under control channel jamming attacks. In future work, we will investigate

modifications to the adversarys jamming strategy and the effect on the availability of control

messages and the ability to identify compromised users.

Multi Server Communication In Distributed Management System

Abstract: This approach has the potential of both distributing the operation processing load

among the proxies and enabling clients to access the service by communicating with nearby

proxies rather than a potentially distant centralized server. However, achieving even just

serializability for operations executed at these proxies using standard replication approaches

requires that a proxy involve either a centralized server or other (possibly distant) proxies on the

critical path of each update operation. Our system implements a service with a designated server

and an unbounded number of proxies. We generically refer to the server and the proxies as

processes. To support the service, a proxy joins the service. In doing so, it is positioned within a

tree rooted at the server. All proxies in the subtree rooted at that child are said to disconnect. The

child (or, if the child failed, each uppermost surviving proxy in the subtree) can inform its

subtree of the disconnection. The subtree can stay put until the disconnection heals, or they

might reconnect via the server.

Abstract: This project presented a novel approach for reducing the spatial query access latency

by leveraging results from nearby peers in wireless broadcast environments. Significantly, our

scheme allows a mobile client to locally verify whether candidate objects received from peers are

indeed part of its own spatial query result set. The experiment results indicate that our method

can reduce the access to the wireless broadcast channel by a significant amount, for example, up

to 80 percent, in a dense urban area. This is achieved with minimal caching at the peers. By

virtue of its P2P architecture, the method exhibits great scalability: the higher the mobile peer

density, the more the queries answered by peers. Therefore, the query access latency can be

markedly decreased with the increase in clients.

requires that a proxy involve either a centralized server or other (possibly distant) proxies on the

critical path of each update operation. Our system implements a service with a designated server

and an unbounded number of proxies. We generically refer to the server and the proxies as

processes. To support the service, a proxy joins the service. In doing so, it is positioned within a

tree rooted at the server. All proxies in the subtree rooted at that child are said to disconnect. The

child (or, if the child failed, each uppermost surviving proxy in the subtree) can inform its

subtree of the disconnection. The subtree can stay put until the disconnection heals, or they

might reconnect via the server.

Intercity Search Query Processing

Abstract: This project presented a novel approach for reducing the spatial query access latency

by leveraging results from nearby peers in wireless broadcast environments. Significantly, our

scheme allows a mobile client to locally verify whether candidate objects received from peers are

indeed part of its own spatial query result set. The experiment results indicate that our method

can reduce the access to the wireless broadcast channel by a significant amount, for example, up

to 80 percent, in a dense urban area. This is achieved with minimal caching at the peers. By

virtue of its P2P architecture, the method exhibits great scalability: the higher the mobile peerdensity, the more the queries answered by peers. Therefore, the query access latency can be

markedly decreased with the increase in clients.

In this project, we addressed the mitigation of control channel jamming by malicious colluding

insiders and compromised system users as well as the identification of compromised users

without prior knowledge of the number of compromised users in the system. We mapped the

problem of control channel access that is robust to jamming by compromised users to the

problem of secure key establishment under node capture attacks. Based on the mapping, we

proposed a framework for control channel access schemes using random key assignment. We

proposed and evaluated metrics for resilience and delay which quantify the availability of control

messages under control channel jamming attacks. In future work, we will investigate

modifications to the adversarys jamming strategy and the effect on the availability of control

messages and the ability to identify compromised users.

Multi Server Communication In Distributed Management System

Abstract: This approach has the potential of both distributing the operation processing load

among the proxies and enabling clients to access the service by communicating with nearby

proxies rather than a potentially distant centralized server. However, achieving even just

serializability for operations executed at these proxies using standard replication approaches

requires that a proxy involve either a centralized server or other (possibly distant) proxies on the

critical path of each update operation. Our system implements a service with a designated server
