Even though role-based access control (RBAC) can tremendously help us minimize the complexity in administering users, it is still needed to realize the notion of roles at the reso...
The design of ubiquitous and embedded computers focuses on cost factors such as area, power-consumption, and performance. Security and trust properties, on the other hand, are oft...
— The recent advances of distributed hash tables (DHTs) facilitate the development of highly scalable and robust network applications and services. However, with applications and...
Recent secure code-update protocols for sensor networks have been based on asymmetric-crypto primitives such as digital signatures. Our approach, Castor, explores the feasibility ...
Wireless Sensor Network (WSN) deployed in hostile environments suffers from severe security threats. In this paper, we propose a Secure Message Percolation (SMP) scheme for WSN. We...
