SECURED PAYMENT ON BLOCKCHAIN FOR OUTSOURCING SERVICES IN CLOUD COMPUTING

Abstract

Cloud computing has revolutionized outsourcing services, yet concerns about online payment security and mutual distrust persist. Existing solutions often rely on trusted third parties, limiting their applicability. To address this, we introduce BPay, a novel framework leveraging blockchain technology to enable a payment system that is both secure and equitable.for outsourcing services without intermediaries. We introduce the system framework, adversary model, and objectives of BPay, emphasizing its compatibility with Bitcoin and Ethereum blockchains. Security and compatibility analyses demonstrate BPay's robustness and efficiency. Cloud computing has revolutionized the manner in which outsourcing services are delivered and accessed, offering unprecedented scalability, flexibility, and cost-effectiveness. However, despite its numerous benefits, concerns about the security of online payments and the lack of trust between users and service providers continue to pose significant challenges. Traditional payment systems often rely on trusted third parties to facilitate transactions, which can introduce vulnerabilities and increase the risk of fraud or data breaches. These limitations hinder the broader adoption of cloud computing in various industries and applications.
