Abstract

Along with the recent developments in technology and the widespread use of the Internet, an urgent need has arisen for consumers to be fully protected and to have access to reliable safety services, especially when the Internet is used for selling or buying products and other money-related transactions. With this in mind we devised development strategies that ensure privacy in buying and selling transactions. This work focuses on one particular type of transaction, the online sealed-bid auction. This work presents a review of the secret sharing scheme and how this type of cryptography can help to increase security in the environment of the online cloud. The review is followed by an illustration of the ways in which the secret sharing scheme can be used by a cloud provider to create a self-organizing environment and an elucidation of how sealed-bid auctions can be conducted while providing security from attackers.
