Assignee: PALITRONICA INC.
Field: Digital communication (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. A system for monitoring a local network having a plurality of device processors connected thereto, the system comprising:
a. at least one detector operable to generate a program trace signal from at least one side-channel of each device processor of the plurality of device processors;
b. a communication component to provide access to the local network; and
c. at least one monitoring processor in communication with the communication component and the at least one detector, the at least one monitoring processor being operable to:
i. detect a communication of a message on the local network;
ii. identify a device processor of the plurality of device processors as a purported transmitter of the message;
iii. analyze the program trace signal of each device processor of the plurality of device processors relative to the communication;
iv. classify each device processor of the plurality of device processors as being one of transmitting the message or not transmitting the message based on the respective program trace signal; and
v. in response to classifying the purported transmitter of the message as transmitting the message, authenticate the purported transmitter of the message.
