# Utilizing Trusted Lightweight Ciphers To Support Electronic-Commerce Transaction Cryptography
## 1 Introduction  
The online shopping sector, commonly known as e-commerce, has grown dramatically in recent years as a result of technological advancements. More and more customers are choosing to utilize on-line shopping because of the quick advancement in information technology gadgets and Internet connectivity. The evolution of shopping mechanisms is influenced by a variety of social, technological, cultural, and psychological elements, which contribute to e-commerce's success. The most frequently utilized platform on the Internet is probably e-commerce websites, online auctions and mobile applications. Customers or buyers can order high-tech items, digital music files, books, services, etc., through e-commerce. Additionally, electronic apps provide a wide range of services and prospects, such as chances for developing payment invoices, buying and selling operations, and providing electronic services to customers and institutions via the Internet trade progress [1]. According to [2] in 2021, e-commerce sales increased dramatically at the level of countries; for example, the United Kingdom spent USD 169.02 million and the United States spent USD 843.15 million and USD 2779.31 million; this indicates that e-commerce has become a hugely influential economic factor around the world. Due to the rise in credit card theft and compromised client accounts, e-commerce security has lately been a major concern. Compromising of customers' account information and credit card fraud are the two most serious security issues that are known to affect e-commerce [3]. The usage of e-commerce has significantly developed over the past several decades, and as a result, there are now exponentially greater transactions and numbers of payments made on online platforms. E-commerce has sophisticated an explosion of development, leading to security risks that threaten the personal informationof users and attempt to detect private, public, and shared keys [4] in encrypting commercial and personal data/information [5]. Bitcoin, Litecoin, Freicoin, and Peercoin are among the currency-encryption approaches utilized in e-commerce applications. Some of these schemes apply cryptography algorithms to provide confidentiality and secrecy features [6]. It is common for e-commerce applications to be attacked (see Figure 1) by the types of common risks such as distributed denial of service (DDoS), phishing, wiretapping, brute force (BF), distributed guessing, financial fraud, sabotage, modification, ransomware, sniffer and zero-day. For instance, by producing a large number of malicious requests, a DDoS will crash the e-commerce applications and make them unusable for customers. Furthermore, e-commerce requests may be collected and modified through wiretapping on the transferred transaction encryption over the Internet. In addition, hackers use phishing attacks to capture the confidential information of customers through the creation of fake websites that are similar to real websites. Moreover, by using all possible combinations of characters, BF will crack passwords. Customers' private data and payment transactions have become major concerns [7]. Furthermore, financial fraud is committed through the theft of private information from credit cards when e-commerce platforms use this method to purchase services and products. Additionally, it occurs through false requests for credit returns through unauthorized transactions. A report published by [8] indicates that e-commerce attacks are constantly increasing; for example, from 2020 to 2021, there was an increase in credit card fraud attacks from 65% to 68%, BF from 11% to 11.5%, phishing from 56% to 71%, etc. This report also indicated that security-related incidents on Black Friday/Cyber Monday accounted for 17.5% of the total number of e-commerce requests. According to the report [9], 62% of attacks against e-commerce were automated. E-commerce transactions are exposed to various types of threats and attacks due to the rapid development of Internet websites; therefore, the system becomes unsafe.
