In Secure Electronic Transaction, the purpose of Dual Signature is to link two messages that are intended for two different recipients. Discuss these two messages that are intended for two different recipients along with the need of linking. Also discuss if this purpose is fulfilled if we use KUc instead of KRc in the given model. Justify your answer with appropriate discussion.

The analysis of the question is summarized in the following explanation.

Explanation:

The dual signature would be intended as a connector for both signals, we can clearly distinguish between the transmit antennas by delivering each statement with such a separate signing, thus making the linkage of certain messages possible via the World wide web.No violation of the records allows data easily accessible to a third party so we can improve the safety of 2 statements linking, because nobody can identify how the data have been authenticated as well as how the text could be decrypted to gather intelligence.
