Blockchain based Confidentiality and Integrity Preserving Scheme for Enhancing E-commerce Security

In recent years, Electronic Commerce (E-commerce) applications are attracting many users and merchants to conduct their daily business online which includes payment of bills, online banking, buying tickets and purchasing goods etc. E-commerce transaction security is a major concern for E-commerce websites along with its customers. The basic requirements for any E-commerce transaction are privacy, authentication, integrity and non-repudiation. In this paper, a transaction processing system (TPS) for E-commerce by using a Blockchain technology, zero-knowledge proof and modified elliptic curve cryptography encryption is proposed. Also a denial of service attack detection model for the E-commerce system is proposed which take care of the DoS attack during E-commerce transactions.
