✦ Synopsis

In this paper, a dynamic user hierarchy me~ based on key pairs is proposed. Through careful design of keys, we get an economic integer key ~ for each nser. In our scheme, the relationship between two users can be easily revealed by performing s simple formula to the key pair. Furthermore , by applying our scheme, whenever a new user is inserted into the user hierarchy system, the corresponding key pair can be determined quickly without changing any existing key pairs.
