Abstract:
1. A system for tamper-resistant communication in a network node, comprising: a log capture system residing in a tamper-resistant communication layer storing message statistics and message data including node communication activity data with other nodes in a network passing through the tamper-resistant communication layer in a data memory device disposed between a network layer and a link layer of a network protocol stack; a log query system residing in the tamper-resistant communication layer, and electronically requesting node communication activity data from the log capture system, the log query system determines whether a query by other node in the network is related to the node communication activity data stored in the log capture system; a log reply system residing in the tamper-resistant communication layer, and electronically transmitting node communication activity data in response to a query by the log query system, the log reply system determines whether transmission of the node communication activity data is responsive to the query; a multi-hop forwarding system residing in the tamper-resistant communication layer, and detecting whether the message data has been dropped by one or more intermediate nodes in the network; and a route error management system residing in the tamper-resistant communication layer, and analyzing a route error message generated by a routing protocol, and forwarding the route error message to one or more nodes in the network.
