Anonymous Communication via Anonymous Identity-Based Encryption and Its Application in IoT

Abstract EN

Under the environment of the big data, the correlation between the data makes people have a greater demand for privacy.

Moreover, the world has become more diversified and democratic than ever before.

Freedom of speech is considered to be very important; thus, anonymity is also a very important security demand.

The research of our paper proposes a scheme which can ensure both the privacy and the anonymity of a communication system, that is, the protection of message privacy while ensuring the users’ anonymity.

It is based on anonymous identity-based encryption (IBE), by which the users’ metadata are protected.

We implement our scheme in JAVA with Java pairing-based cryptography library (JPBC); the experiment shows that our scheme has significant advantage in efficiency compared with other anonymous communication system.

Internet-of-Things (IoT) involves many devices, and privacy of devices is very significant.

Anonymous communication system provides a secure environment without leaking metadata, which has many application scenarios in IoT.
