—Pervasive computing is fast becoming a reality with rapid advance in computing and networking technologies. It has the characteristics of scalability, invisibility, and the abse...
In this work we propose a new stream authentication scheme that is suitable for live packet streams distributed over a lossy channel, such as an IP-multicast group. Packets are si...
Many modern computing environments involve dynamic peer groups. Distributed simulation, multi-user games, conferencing and replicated servers are just a few examples. Given the op...
We investigate unconditional security for message authentication protocols that are designed using two-channel cryptography. We look at both noninteractive message authentication ...
