Abstract
A system and method of performing cooperative non-repudiated message exchange from a first system to a second system in a computer network comprises checking for discrepancies between a current system time in the second system with an actual time; performing a time synchronization process to match the current system time with the actual time; exchanging public encryption keys between the first and second systems; sending a digitally signed message from the first system to the second system; decoding the digitally signed message; sending a digitally signed acknowledgment message from the second system to the first system; decoding the digitally signed acknowledgment message; and committing text of the digitally signed message to an official transcript on the first system.
