nonrepudiation

   Also found in: Wikipedia 0.01 sec.
nonrepudiation
Not denying or reneging. Digital signatures and certificates provide nonrepudiation because they guarantee the authenticity of a document or message. As a result, the sending parties cannot deny that they sent it (they cannot repudiate it). Nonrepudiation can also be used to ensure that an e-mail message was opened (see e-mail tracker).
