We propose a new cryptographic technique, Acknowledgment Compression, permitting senders of multicast data to verify that all interested parties have either received the data or l...
Signcryption is a new cryptographic primitive which simultaneously provides both confidentiality and authenticity. This paper proposes an improved signcryption scheme and a varia...
We propose a lightweight fault-tolerant multicast and membership service for real-time process groups which may exchange periodic and aperiodic messages. The service supports boun...
