WebNon-repudiation is an active attempt to creat artifacts which may be used against an identified person who is denying that they are the origin of a communication or action. … WebIn cryptography, digital signatures are used to check for non-repudiation. This basically means that we are digitally signing a message or file. In this case, no type of encryption on the message is required since with the digital signature, an individual is in a position to verify that the message came from one and was not changes in the course.
