Study of cryptography-based cyberspace data security

The definition of cyberspace, characteristics of cyberspace data and the security risks are analyzed firstly. The cyberspace data security assurance architecture is then elaborated. On the basis of that, cryptography-based cyberspace data security reference model is designed. According to this model, the basic procedure and key technology of cyberspace data protecting are researched through data generation, data transmission, data storage, data usage and data destruction of the full lifecycle. In this paper, we study the cyberspace data security from a perspective of technological framework, looking forward to make a useful attempt at solving this problem.
