Cyberspace security

With rapid development and wide application of information technology, mankind is entering into an information age. The world where people live and work has been changed to a brand new triple-dimensional space that consists of the physical world, the human society and the cyberspace. It is well known that the cyberspace is an essential environment of human existence and development and it is the set of all information systems. So the cyberspace security should be guaranteed. In the current cyberspace, a serial of new information systems such as cloud computing, cyber physical systems, smart home systems, and big data systems bring many new security requirements. Meanwhile, the new computing models such as quantum computing and DNA computing are challenging traditional information security. All of the above foster a worldwide hot research focus on cyberspace security.
