LARGE-SCALE SIMULTANEOUS DIGITAL SIGNATURE SERVICE SYSTEM BASED ON HASH FUNCTION AND METHOD THEREOF
First Claim
1. A system for a large-scale simultaneous digital signature service based on a hash function, comprising:
- a plurality of digital signature target terminals;
a plurality of digital signature service provision servers for providing a large-scale simultaneous digital signature service based on distributed processing of a hash chain of a hash tree in response to a request to generate a digital signature from each of the digital signature target terminals;
a digital signature service configuration server for constructing the hash tree having a hierarchical structure that is preset in order to perform parallel distributed processing for generating a large-scale digital signature according to a digital signature service performance right based on unique authentication information provided by each of the digital signature service provision servers; and
a digital signature service relay server for enabling access to any one digital signature service provision server, selected from among currently available digital signature service provision servers, in response to a request for accessing the digital signature service from each of the digital signature target terminals.

Abstract
Disclosed are a system and method of a large-scale simultaneous digital signature service based on a hash function. According to the system and method, the main agent that requires the generation of a digital signature does not itself generate the digital signature, and digital signatures may be simultaneously and stably generated for large-scale data such as multiple electronic documents and digital data, using a hash function and a hash tree, which are known as a simple and secure method, to guarantee the integrity of the data in a digital signature-based structure based on multiple servers.

9. A method of performing a large-scale simultaneous digital signature service based on a hash function, using a system including a plurality of digital signature target terminals, a plurality of digital signature service provision servers, and a digital signature service relay server, the method comprising:
-
(a) constructing, by the digital signature service configuration server, a hash tree having a hierarchical structure that is preset in order to perform parallel distributed processing for generating a large-scale digital signature according to a digital signature service performance right based on unique authentication information provided by each of the digital signature service provision servers; (b) relaying, by the digital signature service relay server, a connection in order to enable access to any one digital signature service provision server, selected from among currently available digital signature service provision servers, in response to a request for accessing a digital signature service from each of the digital signature target terminals; and (c) providing, by the digital signature service provision server selected in step (b), a large-scale simultaneous digital signature service based on distributed processing of a hash chain of the hash tree constructed in step (a) in response to a request to generate a digital signature from each of the digital signature target terminals. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)
