Example Embodiment

[0025] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other if there is no conflict. Hereinafter, the present invention will be described in detail with reference to the drawings and in conjunction with the embodiments.

[0026] In the present invention, the constructed network environment includes buyers, auctioneers and auction agents. The auctioneer sells spectrum resources to buyers through auction; the buyer will use the spectrum resources obtained from the auction to provide services to users; the auction agent is responsible for assisting the auctioneer to complete the privacy protection of buyer information. The auctioneer here can be a computing server; a buyer can be a client host or server, providing services to customers; and an auction agent can be an assisting server.

[0027] First, the auctioneer and the auction agent collaborate to perform a series of secure interaction operations to group b...

Abstract

The invention discloses a privacy protecting heterogeneous spectrum allocation method which comprises the following steps: performing initialization; submitting quotation; perfomring safe grouping; calculating an interference pattern, displacing the interference pattern, double encrypting the quotation information and sending the encrypted quotation information to the auction broker by the auctioneer; executing a grouping algorithm, encrypting the buyer identity after displacement for each group of members, randomizing all double-encrypted quotation information, and sending the grouped safe operation result to the auctioneer by the auction broker; decrypting the outer-layer encryption of the randomized double-encrypted quotation information by the auctioneer; performing winner selection, namely generating an encryption circuit corresponding to the auction algorithm, wherein the circuit realizes group pricing and winner selection function, and sending the encryption circuit to the auctioneer by the auction broker; receiving the encryption circuit by the auctioneer, secretly sharing the buyer pricing information and buyer identity with the auction broker, and calculating the encryption circuit; and performing final pricing. In the invention, no information related to quotation except the auction result is disclosed in the auction process.

Description

technical field [0001] The invention relates to the technical field of network and information security, in particular to a privacy-protecting heterogeneous frequency spectrum allocation method based on encryption circuits and homomorphic encryption technology. Background technique [0002] Wireless spectrum is a limited resource. With the wide application of various wireless communication technologies, people's demand for spectrum resources is increasing day by day, and the problem of scarcity of spectrum resources is becoming more and more prominent. With the help of an appropriate auction mechanism, dynamic spectrum auction reallocates the idle frequency bands of original users to new users, improves the utilization efficiency of spectrum resources, and alleviates the problem of spectrum scarcity. It has gradually become an effective spectrum allocation method. [0003] At present, most dynamic spectrum auction mechanisms consider the homogeneous spectrum auction problem...
