Practical ID-Based Encryption for Wireless Sensor Network

Free registration required

Executive Summary

In this paper, the authors propose a new practical identity-based encryption scheme which is suitable for Wireless Sensor Network (WSN). The authors call it Receiver-Bounded Online/Offline Identity-based Encryption (RB-OOIBE). It splits the encryption process into two parts - the offline and the online part. In the offline part, all heavy computations are done without the knowledge of the receiver's identity and the plaintext message. In the online stage, only light computations such as modular operation and symmetric key encryption are required, together with the receiver's identity and the plaintext message.
