Practical ID-based Encryption for Wireless Sensor Network

In this paper, we propose a new practical identitybased encryption scheme which is suitable for wireless sensor net work (WSN). We call it Receiver-Bounded Online/Offtine Identity-based Encryption (RB-OOIBE). It splits the en cryption process into two parts - the offiinc and tie on line part. In the offine part, all heavy computations are done without the knowledge of the receivers identity and the plaintext message. In the online stage, only light com putations such as modular operation and symmetric key en cryption arc rcquired, together with the receivers identity and the plaintext message. Moreover, since each ofttine ci phertext can be re-used for the samc receiver, the number of offline ciphertexts the encrypter holds only confines the number of receivers instead of the number of messages to be encrypted. In this way, a sensor node (with limited computa tion power and limited storage) in WSN can send encrypted data easily: A few offline ciphertexts can be computed in the manufacturing stage while the online part is light enough for the sensor to process.
