Abstract—In this paper, we summarize the basic schemes of attribute based encryption and analyze the differences and relationships of their structures. Further, we point how to add new functions to these basic ABE schemes, such that new functions can be combined into basic algorithms. Then we introduce and analyze some existing ABE schemes with functions of hidden policy, multi-authority, and traitor tracing. We analyze the characteristic of these schemes and show their embedded methods in detail.

Index Terms—Attribute based encryption, hidden policy, multi-authority, traitor tracing.
