They would like to share and use the personal information and industry secure information safely in the Internet of Things environments. In particular, large amounts of data collected through the sensor may be personal confidential information. Therefore, it is very important to share this safely. There is a CP-ABE as a method for share data safely on the cloud server. This method uses the approach policy that reflects the static attribute in order to share data safely. However, this approach is difficult to reflect the dynamic attributes that change with time. Accordingly, we provide a design approach structure that reflects the dynamic characteristics of the sensing data attributes. In other words, we will try to design the access structure of a new approach that takes into account the sensitive data. And according to a new approach structure, we are trying to reconfigure the existing sensing policy such as decrypt policy that can present by conditional tree. We will analyze the dynamic situation of the sensing data using the Bayesian network statistical method that based on context service reasoning model, because we want to design attribute based Re-encrypt method according to new sensing policy. Our new attribute based re-encrypt scheme may be more secure against CP-ABE about data diversity and secure data share ability.
