Abstract

Παρέχεται ένα σύστημα και μια μέθοδος για την παραγωγή ενός ψηφιακού πιστοποιητικού όπου λαμβάνεται μια νέα ψηφιακή εγγραφή και εκχωρείται μια τιμή ακολουθίας. Παράγεται μια πρώτη σύνθετη ψηφιακή τιμή με την εφαρμογή μιας πρώτης προσδιοριστικής συνάρτησης στις ψηφιακές εγγραφές που έχουν αποθηκευτεί σε έναν χώρο αποθήκευσης. Η τιμή ακολουθίας και η πρώτη σύνθετη ψηφιακή τιμή περιλαμβάνονται σε ένα πρώτο πιστοποιητικό. Μετά την προσθήκη της ψηφιακής εγγραφής στον χώρο αποθήκευσης, παράγεται μια δεύτερη σύνθετη ψηφιακή τιμή με την εφαρμογή μιας δεύτερης προσδιοριστικής συνάρτησης στις ψηφιακές εγγραφές στον χώρο αποθήκευσης. Αυτή η δεύτερη σύνθετη ψηφιακή τιμή, και μια σύνθετη τιμή ακολουθίας, δημοσιεύονται. Μια ψηφιακή τιμή διαστήματος η οποία βασίζεται στην πρώτη και δεύτερη σύνθετη ψηφιακή τιμή, και η τιμή ακολουθίας, περιλαμβάνονται σε ένα δεύτερο πιστοποιητικό το οποίο συνεπώς επαληθεύει την αυθεντικότητα και τιμή ακολουθίας της ψηφιακής εγγραφής.
