Filed: 2002-02-18
Abstract: <P>PROBLEM TO BE SOLVED: To enable an accepting means to permanently verify an authentication certificate without being restricted by the expiration date of the authentication certificate by a creating means.  <P>SOLUTION: A creating means 1 creates a document A including an electronic document 3 and an electronic signature 31 having a creator authentication certificate 311 (1), and issues a request to a certification authority 5 to certificate a fact that the electronic signature of the document A was done (2). The certification authority 5 verifies whether or not the authentication certificate 311 is valid at the time point of the certification using a PKI 6 (3) and (4); issues and sends a digital receipt 4 of the certification authority 5 including an authentication certificate 411 and a certification fact 42 having a verified result 422 to the creating means 1 (5). The creating means 1 creates a document B corresponding to an integrated combination of the document A and the digital receipt 4 (6), and sends the document B to an accepting means 2 (7). The accepting means 2 verifies the validity of the digital receipt 4 using the PKI 6 if the valid date is within the valid duration of he authentication certificate 411 (8) and (9); and if the valid date is out of the valid duration, verifies the electronic signature by the verification (10) and (11) using the certification authority 5.  <P>COPYRIGHT: (C)2003,JPO
