Nowadays, the demand for wireless spectrum resources is growing rapidly with the continuous development of wireless communication technology. However, the vast majority of available spectrums have been allocated, making the new demanders have difficulty to acquire their appropriate spectrums. In order to reallocate the scanty spectrum resources for new demanders, many spectrum auction schemes that are based on truthfulness are proposed. However, the insufficient protective measures been deployed in these schemes made the users private information be easily exposed during the process of the spectrum auction. By combining homomorphic encryption and garbled circuits technology, this paper proposes a secure and efficient collaborative spectrum auction scheme for redistributing the scarcity spectrum resources. Furthermore, the security of the protocol used in the scheme has been proved. The emulation experimental results have demonstrated that the proposed scheme can effective enhance the privacy information of the spectrum users while consume relatively lower computing and communicating overhead.
