A Secure and Fair Double Auction Framework for Cloud Virtual Machines

Blog Article

Double auction is one of the most promising solutions to allocate virtual machine (VM) resources in two-sided cloud markets, which can increase the utilization rate of VM resources.However, most cloud auction mechanisms simply assume that the auctioneer is fully trusted while ignoring bid-privacy preservation and trade fairness in the process of auction.Previous studies have indicated apac1/60/1/cw that some cryptographic tools can be used to resolve the above issues, but the poor performance makes those techniques difficult to practice.In this paper, we propose a Secure and Fair Double AuCtion framework (named SF-DAC) for cloud virtual machines, which performs cloud auction efficiently while guaranteeing both bid privacy and trade fairness.

We design secure 3-party computation protocols that support secure comparison and secure sorting, which enable us to construct a secure double auction scheme that outperforms all prior comparable solutions.Furthermore, we iphone 14 price miami propose a fair trading mechanism based on smart contracts to prevent the bidders from halting the auction without financial penalties.The extensive experiments demonstrate that SF-DAC achieves an order of magnitude reduction in computation and communication costs than prior arts.
