A decentralized public key management system for named data networks based on blockchain, which solves the Compromised Certificate Authority (CA) Problem. The system divides the power of an individual CA among multiple Public Key Miners (PKMiners) that maintain the public key blockchains. The majority rule in name-principal validation allows the present invention to tolerate compromised PKMiners without causing any damage.

Blockchain-based decentralized public key management system

A Forwarding Information Base (FIB) caching system and scheme that selects and generates a minimal number of non-overlapping prefixes for the FIB cache to improve computer-based network communications and operations efficiency, accuracy and speed. Because the cached prefixes do not cover any longer prefixes in the full FIB, the present invention thus avoids cache-hiding issues. The system further comprises a FIB caching updating component that systematically handles cache misses, cache replacement, and routing updates.

Efficient forwarding information base caching system and method

A system for detecting object movement including a sensory network having at least one sensory device using modulated radar for detecting an object in proximity to the sensory network. The sensory network including wireless transmission means and a base station having computer processing means located remote from the sensory network and including wireless transmission means to communicate with the sensory network. The base station having computer readable program code means for causing the computer processing means to analyze data received from the sensory network to determine motion characteristics of the object in proximity to the sensory network.

Surveillance and tracking system and method

A system for detecting object movement including a sensory network having at least one sensory device using modulated radar for detecting an object in proximity to the sensory network. The sensory network including a wireless transmission system and a base station having a computer processing system located remote from the sensory network and including a wireless transmission system to communicate with the sensory network. The base station having a computer readable program code for causing the computer processing system to analyze data received from the sensory network to determine motion characteristics of the object in proximity to the sensory network.

Networking devices and methods for forwarding information base (FIB) aggregation are provided. A networking device includes a processor operable to access entries in a FIB, and aggregate the FIB entries to produce an aggregated FIB with strong forward correctness. In aggregating the FIB entries, the processor is operable to: (a) associate the FIB entries with nodes (n) in a patricia trie; (b) traverse the patricia trie depth-first in post-order and determine for each node a next-hop set, without expanding the trie, by merging what would be the next-hop sets of its imaginary children nodes if there is a complete binary tree; and (c) traverse the patricia trie depth-first in pre-order, select for the root node a next-hop from its next-hop set and include the FIB entry associated with the root node in the aggregated FIB, for each node having a selected next-hop that appears in its child's next-hop set, select that next-hop for the child as its next-hop and exclude the FIB entry associated with the child node from the aggregated FIB, and for each child node which does not have in its next-hop set the selected next-hop of its parent, select a next-hop from its next-hop set and include the FIB entry associated with the child node in the aggregated FIB.
