Abstract

A fault-tolerant failsafe computer voting system includes a switch module that generates a first copy of a first data packet and a second copy of the first data packet and that communicates the first copy and the second copy. The system also includes a first voting module that generates a first packet signature based on the first copy and communicates the first packet signature. The system further includes a second voting module that generates a second packet signature based on the second copy and communicates the second packet signature.
