Secure Control Model of Sensitive Information Based on Dynamic Trust Measurement
Rong Zeng · Computer Technology and Development · 2012
With the rapid development of information technology,the size of sensitive information handled by computer systems is growing.To ensure the security of sensitive information becomes very important.In this paper,the traditional multi-level security model BLP model is analyzed and pointed out its lack of integrity protection of sensitive information which is security risks.Against the security risks,a secure control model of sensitive information based on the dynamic trust measurement(DTMSISCM) is designed in this paper and a framework for its implementation is also given.DTMSISCM implements sensitive information control through trust degree and it maintains the same confidentiality as BLP model.Furthermore,it can ensure the integrity of sensitive information and improve the system availability of sensitive information security controls.
