non-repudiation

1. General: Intent to accept one's obligation under a contract and be bound for its performance.

2. Electronic commerce: Intent to accept responsibility of submitting or receiving an electronic message and be bound by its substance. Non repudiation protects a sender against the false assertion of the receiver that the message has not been received, and a receiver against the false assertion of the sender that the message has been sent. An essential element of secure electronic commerce, non repudiation is generally established by the protocol (such a public key infrastructure or EDIFACT) used in data transfer, and includes legal and security criteria of authentication and report integrity.
