A secure information flow architecture for public web service

Cyber hacking has been increased every year and it has resulted in severe damages and losses to companies to the extent that it may lose whole business. Recent trend of hacking shows that aims of hacking is to get personal information profile as many as possible, such as ID, residential registration number, password, etc, and to use it for other purposed. The prominent target of hacking is the database of company. This thesis aims to suggest one way data transmission method as one of network partition solutions for the purpose of protecting database where critical information is stored, even when server is attacked and damaged by hacking. The suggested architecture reduced transmission time for data exchange, a problem in existing architectures, for example between web server and Database, to enable real-time safe transmission of even large-scale data.
