Study on the knowledge security architecture of enterprise Knowledge management

In the era of knowledge-based economy, instead of labor force and capital, knowledge has become the most important source and the core productive force for worth creation. Now, the number of scholars and executors attaching importance to knowledge is increasing. And then, Knowledge management (KM) is regarded as the efficient and effective management mode and means to improve or rebuild enterprise core competence. However, with the process that the meaning and significance of knowledge grows more and more apparent, there are more and more hackers, crackers or other destroyers (including some competitors), and the risk of knowledge security accident becomes bigger and bigger. In this paper, something about knowledge safe is introduced, firstly. And then, the knowledge security architecture is analyzed, designed and brought forward, which has three defenses: knowledge access control, knowledge steganography and knowledge encryption. Furthermore, the technical thought, theory and implementing mechanism of every defense mentioned above is widely and deeply analyzed and discussed. Simultaneously, some examples about the technique used are demonstrated and explained. All the work is expected to be helpful to strengthen and improve enterprise knowledge security.
