| Summary: | 碩士 === 中國文化大學 === 資訊管理學系 === 98 === The data must keep security in the computer system. We collect all data (news) and broadcast them to all users. We avoid the data to be modified by attacker and broadcast the wrong message. We propose the method to collect the news and store them in computer system in security. We encrypt the news and store the encrypted news in the encrypted news database. Before we want to broadcast, we decrypt the encrypted news.
In this study, we set encryption data table and use it to encrypt the news file to encrypted news data. All news have different location code in the news information database. We use location code to insert encryption data table to encrypted news and store the encrypted news to encrypted news database. In this paper, we propose the method of verification to check the encrypted news is modified or not. When we install these algorithms in the computer system to process, it is more secure.
