Study of session based dynamic light weight schemes with elliptic curve cryptography for secure e commerce system

Abstract

E-commerce is the systems that use the web or electronic media for online commercial activities that includes services and goods buying and selling, procurement on agreement of terms, comparison for best choice, placing order and authentication, inventory processing, shipment and rapport of customer by electronic payment system. The transaction related to commercial activities will occur in different ways such as business to business, business to consumer, consumer to consumer, peer to peer transaction or in consumer to business manner. newlineThe privacy and anonymity are considered as an important factor, while communicating over publicly in the platform like web. To ensure a high level of security, streamlined random and padding scheme in session portion of internet usage along with crypto system are used that grants high security for small bits of key size. Elliptic Curve Cryptosystem (ECC) uses smaller keys for equivalent strength compared to traditional public- key cryptosystems, the difference in key size increases as security desires to increase. The proposed work is carried out in three phases. newlineDuring the first phase, session based light weight cryptography to improve the performance of web service security is proposed. In this method, at each session the values for ECC is initialized and sent to the user during the starting of the session. Whenever the user access the web service, the method randomly selects the point from the given key set which is used as an encryption key to produce the request. The generated XML file is sent to the server side which identifies the key from the received point. From that point, the proposed method identifies the key being used to perform decryption. Using the identified key, the method extracts the original content to perform the required operation. newline
