    This paper focuses on the design and implementation of the online auction of university's text book and the way to promote trustworthy of using it. The paper considers three main problems such as no stop center to collect and resell the second hand text book among universities in Malaysia, inappropriate price of second hand text book and not enough information about second hand text book. The interesting problem is lack of trustworthy in using online auction among Malaysian. The research examines cryptography technology to establish a new auction model which verifies every step of the auctioneer. Analysis results demonstrate that the proposed model satisfies various requirements included fairness and privacy

    Integration of Blockchain and Auction Models: A Survey, Some Applications, and Challenges

    Get PDF
    In recent years, blockchain has gained widespread attention as an emerging technology for decentralization, transparency, and immutability in advancing online activities over public networks. As an essential market process, auctions have been well studied and applied in many business fields due to their efficiency and contributions to fair trade. Complementary features between blockchain and auction models trigger a great potential for research and innovation. On the one hand, the decentralized nature of blockchain can provide a trustworthy, secure, and cost-effective mechanism to manage the auction process; on the other hand, auction models can be utilized to design incentive and consensus protocols in blockchain architectures. These opportunities have attracted enormous research and innovation activities in both academia and industry; however, there is a lack of an in-depth review of existing solutions and achievements. In this paper, we conduct a comprehensive state-of-the-art survey of these two research topics. We review the existing solutions for integrating blockchain and auction models, with some application-oriented taxonomies generated. Additionally, we highlight some open research challenges and future directions towards integrated blockchain-auction models

    The evolution of the auction market has been on the upswing throughout the years as technology evolves at an accelerating rate. With the advanced technology nowadays, digital transformation has been applied to the auction markets as a means of transferring goods or services in an online form. Electronic auctions enable sellers to reach a broader range of prospective bidders and participate in the auctions anywhere-anytime. Nevertheless, the security aspects of the e-auction system have become the main concerns for the parties involved. Hence, a secure cryptographic electronic auction system is proposed by employing the underlying cryptographic schemes as the building blocks, namely, asymmetric encryption, digital signature scheme, and hash functions. The proposed e-auction system fulfills the security requirements, encompassing anonymity, correctness, confidentiality, privacy, integrity, and fairness. Performance analysis has also been performed on our proposed e-auction system
