ABSTRACT

With the rapid development in the technology industry, electronic information has gradually become one of the most essential means of human interaction (Gu & Yao, 2003). People today frequently exchange information electronically at all security levels and therefore, the security protection of electronic information shares a close relationship with a country’s politics, economics, military and diplomatic affairs, as well as an individual’s personal life. While electronic information makes modern life more convenient, there are also many underlying risks, such as illegal and stolen data, interception and copying. Therefore, electronic information security is irreplaceable in protecting the value of information and has been a research topic that scholars have focused on the most (Zhang, 2005).
