Lightweight Anonymous Communication Model Based on Anonymous IBE

Abstract

With increasing application of big data technology, a large amount of personal information is stored and processed on the Internet, which makes people have a greater demand for privacy. In addition, the development of mobile Internet and cloud computing requires the communication model to be as efficient and low-bandwidth as possible on the basis of security. In order to achieve the goal of protecting users’ data privacy, this paper firstly presents a new anonymous Identify-Based Encryption (IBE) scheme, and designs a new lightweight anonymous communication model by introducing the proposed anonymous IBE scheme into an anonymous communication model. This model effectively guarantees the anonymity of system users and the security of messages in the communication process. Performance analysis shows that our communication model can effectively resists node eavesdropping, traffic analysis attacks, and finally achieve communication security and anonymity. Compared with other anonymous communication systems, our scheme has significant advantages in efficiency and relatively low cost. In the future, it has good application prospects.
