Abstract:

The existing role based access control (RBAC) is a kind of static access control method. A user can only be mapped to a fixed role, and can’t meet the dynamic relationship between user and role in this method. This paper, according to the characteristics of mobile Internet, introduces the location state and time state, gives the access control method based on dynamic trust in mobile Internet environment. The same user has different roles in different location states and time states, and has different access permissions. At the same time, user trust degree is no longer immutable, user’s trust will increase or decrease with access to different resources, and user’s trust degree will decreasing with the passage of time. By dynamically adjusting the user’s trust degree, it overcomes the shortcomings of the current access control in the mobile Internet environment, and effectively controls the user’s access permission in different conditions. Experiments show that the method is correct and effective.

Key words: mobile Internet, dynamic trust degree, access control
