Data path credentials for high-performance capabilities-based networks

Capabilities-based networks present a fundamental shift in the security design of network architectures. Instead of permitting the transmission of packets from any source to any destination, routers deny forwarding by default. For a successful transmission, packets need to positively identify themselves and their permissions to the router. The analysis of the data path credentials data structure that we propose shows that as few as 128 bits are sufficient to reduce the probability of unauthorized traffic reaching its destination to a fraction of a percent.
