Linear feedback shift register and integer theory: a state-of-art approach in security issues over e-commerce

Abstract

Electronic commerce is the buying and selling of goods and services, or the funds transfer between independent organizations and/or persons over an electronic wireless network, primarily the Internet. It focuses on the use of ICT to enable the external activities and relationship among the business and individuals, groups and other business. These business transactions occur in many formats such as business-to-business, business-to-consumer, consumer-to-consumer or consumer-to-business. It is the one type of trading in products or services using wireless networks like Internet or online social media networks etc. Here the computers, telephones, fax machines, barcode readers, credit cards, debit cards, ATM etc. are used for conducting business in e-commerce system. E-commerce includes the activities such as order entry, transaction processing, online payment, authentication, order fulfillment, inventory control, shipment, and customer support. At present most of the people are participating in e-commerce. In E-commerce system privacy and security of user’s information is the most crucial issue at present. Electronic record related to organization or person is sensitive in nature so, it is very significant to impose an advanced security protocol, technical solutions in the system. E-commerce security is the protection of e-commerce assets from unauthorized access, use, alteration, or destruction. In this paper we have focused on security issue like technical safeguards for e-commerce. Our technique proposes an LFSR, pell’s method and Linear congruence based security model for data security in e-commerce. Here two types of keys i.e., intermediate key, session key are used for encryption-decryption and authentication purpose. This new approach of key generation provides extra robustness in our technique. The different types of experiments on this technique and their results conforms that our technique is very secure and efficient for e-business, e-commerce.
