proof of origin

The Proof of Origin belongs to the security services and ensures the protection of the recipient of a message. And it does so in the case when the sender denies being the originator of the message.

Proof of origin is a security service that goes beyond" authentication of the origin of the data". With the authentication of the origin of the data, the recipient can only verify that the data originated from the assumed origin, while the proof of origin enables the recipient to objectively prove, in a way that can be understood by third parties, that the data was generated by a specific originator. The proof of origin is the basis for a legally binding transfer of information.

With asymmetric encryption, in which the plaintext is first encrypted with the secret key and the subsequent decryption is performed with a public key, clear proof of origin is possible.
