THIS: THreshold security for Information aggregation in Sensor networks
Message aggregation can be used to reduce the communication overhead in a network where many messages have the “same” content. However, it may make the network less secure bec...

Dynamic access control: preserving safety and trust for network defense operations
We investigate the cost of changing access control policies dynamically as a response action in computer network defense. We compare and contrast the use of access lists and capab...

Secure hierarchical in-network aggregation in sensor networks
In-network aggregation is an essential primitive for performing queries on sensor network data. However, most aggregation algorithms assume that all intermediate nodes are trusted...
