ikkerepudierbar

ikkerepudierbar is a neologism used in Norwegian-language discussions to describe the quality of being not repudiable; that is, something that cannot be denied, rejected, or renounced with credible justification. The term is formed from the negation 'ikke' (not) and 'repudierbar' (capable of repudiation), itself derived from the verb 'repudieren/répudier' meaning to disown or renounce. As such, ikkerepudierbar characterizes arguments, evidence, or artifacts that are considered incontrovertible or irrefutably attributable.

In practice, the term is mostly encountered in theoretical or linguistic contexts rather than formal law or standard cybersecurity terminology. It is closely related to the English concept 'non-repudiable' or 'non-repudiation.' In information security, non-repudiation describes a property where a party cannot credibly deny a transmitted message or action, typically achieved through cryptographic signatures and audit trails. The Norwegian coinage serves to discuss the edge cases or hypothetical extremes where denial would be deemed impossible.

Usage examples may include: a digitally signed contract with verifiable cryptographic evidence and tamper-evident logging that makes denial impractical; a public record corroborated by independent witnesses.

Critics note that in practice very few artifacts are truly ikkerepudierbare, since all claims can be challenged under some criteria or new evidence.
