How do you ensure non-repudiation?
There are two types of security mechanisms for generating non-repudiation evidence: secure envelopes and digital signatures. A secure envelope provides protection of the origin and the integrity of a message based on a shared secret key between communication parties.
What is non-repudiation example?
Nonrepudiation is the property of agreeing to adhere to an obligation. More specifically, it is the inability to refute responsibility. For example, if you take a pen and sign a (legal) contract your signature is a nonrepudiation device.

non repudiation in a sentence
- The main motivation was the use of low-performance mobile devices for creating digital signatures, considering that such devices could be too slow for creating ordinary public-key digital signatures, such as non repudiation purposes.
- It’s difficult to see non repudiation in a sentence .
