In this paper, a new hierarchy mechanism based on digital keys is proposed. The objective of the mechanism is that the relationships, such as Brother, Father-of, Son-of, and so on, between any two users can be revealed conveniently. This helps in determining whether a file owned by a user may be read, written, or executed by the other users. In our scheme, each user is given a 4-tuple of digital keys. Through careful design of keys, we can get economic keys for each user. Furthermore, the relationship between two users can be easily revealed by performing a simple algorithm. In addition, whenever a new user is appended into the user hierarchy system, the corresponding keys can be determined quickly without changing existing keys.
