non-repudiation

Non-repudiation refers to the assurance that a person cannot deny having performed a particular action, such as sending a message or making a transaction. It ensures that digital communications and transactions are genuine and that the sender cannot later deny their involvement. This is achieved through methods like digital signatures and secure logs, which verify the identity of the parties involved and record the details of the transaction. Non-repudiation helps establish trust and accountability in digital interactions, protecting both the sender and receiver from disputes.
