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.
