Multicast Authentication Framework for Hierarchical Networks using Chinese Remainder Theorem

Broadcast Authentication for Wireless Sensor Networks Using Nested Hashing and the Chinese Remainder Theorem

Secure broadcasting is an essential feature for critical operations in wireless sensor network (WSNs). However, due to the limited resources of sensor networks, verifying the authenticity for broadcasted messages is a very difficult issue. μTESLA is a broadcast authentication protocol, which uses network-wide loose time synchronization with one-way hashed keys to provide the authenticity verifi...

The Chinese Remainder Theorem

Hierarchical Scalable Group Key Management Based on Chinese Remainder Theorem

In this paper, we present a new group key management protocol based on the Chinese Remainder Theorem (CRT), which is developed based on our previous paper [29]. By shifting more computing load onto the key server we optimized the number of re-key broadcast message, user-side key computation and number of key storages. Our protocol, Hierarchical Chinese Remaindering Group Key (HCRGK) Protocol, o...

Framework for Multicast in Hierarchical Networks

We propose a framework for the creation and maintenance of multicast trees in hierarchical ATM networks. This framework aims at coping with an inherent difficulty of topology aggregating in such networks. The main idea of the proposed framework is to distribute the tree topology information among a set of hierarchical Multicast Group Servers (MGSs) nominated for each multicast tree, while keepi...

Robustness in Chinese Remainder Theorem

Chinese Remainder Theorem (CRT) has been widely studied with its applications in frequency estimation, phase unwrapping, coding theory and distributed data storage. Since traditional CRT is greatly sensitive to the errors in residues due to noises, the problem of robustly reconstructing integers via the erroneous residues has been intensively studied in the literature. In order to robustly reco...
