The recipient of asigned message has proof that the message originated from the sender. This qualityis stronger than mere authentication (where the recipient can verify that the messagecame from the sender); the recipient can convince a “judge” that the signer sent themessage. To do so, he must convince the judge that he did not forge the signedmessage himself! In an authentication problem the recipient does not worry aboutthis possibility, since he only wants to satisfy himself that the message came from thesender.", "sig": "363f54dadd4f15de226045d2a99f9f7c3cfa7c1ccbb99f2bb1434a3a2076aedd55f44e4ae31a8e28298338faa908e8b55d332c4b7b90b2048509ea88f7b6f928" }
