Non-repudiation
Definition
Non-repudiation is the property of an electronic signature that makes it impossible for the signatory to deny having performed the action (signing, sending, accepting). It is ensured by the combination of the cryptographic signature (irrefutable technical link), the timestamped audit trail and strong authentication. A qualified signature (QES) offers the strongest non-repudiation recognised by European law.
