Application of E-Auction in University's Text Book Purchasement
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
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
Secure Cryptographic E-Auction System
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
