Abstract
Η εφεύρεση αναφέρεται σε μία συσκευή και σε μία μέθοδο για την επιλεκτική κρυπτογράφηση τμημάτων δεδομένων που στέλνονται μέσω ενός δικτύου μεταξύ ενός διακομιστή και ενός πελάτη. Η συσκευή περιλαμβάνει ένα μέσο συντακτικής ανάλυσης που διαχωρίζει ένα πρώτο τμήμα των δεδομένων από ένα δεύτερο τμήμα των δεδομένων, ένα μέσο κρυπτογράφησης που κρυπτογραφεί μόνο το πρώτο τμήμα των δεδομένων και ένα συνδυαστικό μέσο που συνδυάζει το κρυπτογραφημένο πρώτο τμήμα των δεδομένων, με το δεύτερο τμήμα των δεδομένων, όπου το δεύτερο τμήμα των δεδομένων δεν είναι κρυπτογραφημένο. Η συσκευή περιλαμβάνει επίσης ένα μέσο αποκρυπτογράφησης, το οποίο είναι εγκαταστημένο στον πελάτη, ώστε να αποκρυπτογραφεί το κρυπτογραφημένο τμήμα των δεδομένων. Η συσκευή έχει ανεξαρτησία υπολογιστικού περιβάλλοντος, όσον αφορά τον μορφότυπο των μέσων και το πρωτόκολλο δεδομένων. Η μονάδα κρυπτογράφησης κρυπτογραφεί τα δεδομένα με διαφάνεια προς τον πελάτη με βάση τον μορφότυπο των μέσων. Η συσκευή της εφεύρεσης υλοποιείται ως αντικείμενο εφαρμογής και πρόσθετου προγράμματος. Η μέθοδος για την επιλεκτική κρυπτογράφηση τμημάτων δεδομένων, τα οποία διαφέρουν μεταξύ τους ως προς τουλάχιστον ένα χαρακτηριστικό και στέλνονται μέσω ενός δικτύου μεταξύ ενός διακομιστή και ενός πελάτη, περιλαμβάνει την συντακτική ανάλυση των δεδομένων σε ένα πρώτο και σε ένα δεύτερο τμήμα και την αποστολή του πρώτου κρυπτογραφημένου τμήματος και του δεύτερου τμήματος των δεδομένων στον πελάτη μέσω του δικτύου. Η μέθοδος περιλαμβάνει περαιτέρω την λήψη δεδομένων από τον διακομιστή, τον καθορισμό αν έχει δημιουργηθεί ρεύμα δεδομένων μεταξύ του διακομιστή και του πελάτη και τη
