A Study Of Knowledge Security Access On Knowledge Dissemination

In the era of knowledge economy, position of knowledge is highlighted further. Now, knowledge is the main means of production and is the most source of enterprise core value. Differing from tangible resources, the application benefit of knowledge will be enlarged in knowledge communication and knowledge sharing. However, knowledge must be disseminated on premise that the process is safety; otherwise, the wider range knowledge is disseminated the more seriously negative effect. This paper puts forward a mechanism of knowledge security access aimed at knowledge security in knowledge dissemination.First of all, this paper analyses security threats and safety needs in knowledge dissemination, then the paper studies knowledge management theory, knowledge dissemination theory, trust evaluation theory and access control theory. Based on these theories, the author implements the architecture of knowledge security access mechanism in knowledge dissemination with social-technology perspective. In addition, this study interprets the working mechanism in-depth.Secondly, this study defines structure and function of ecological system, dynamic trust evaluation system and complete access control system of knowledge security access mechanism, Four components of ecological system are studied, the personnel security audit, knowledge safety assessment, knowledge security management and knowledge safety culture. Concept of trust is defined, based on this, factors and mechanisms of trust evaluation are studied; this paper implements three equation models of trust evaluation and interprets the usability of models. To study complete access control system, the author discusses the components, architecture, working mechanism, usability of complete access control system.At last, the above research results are employed in enterprise, ecological system and technological platform are designed. The main models and algorithms are tested.
