Design and implementation of Enhancing the security and performance of Business-to-Business E-Commerce using a Hybrid Model
Electronic commerce is a modern platform that allows buyers and sellers to transact online through an electronic wire without traveling long distances through crossing boundaries. It enables the sellers to penetrate the huge global market by providing goods and services to potential buyers and initiating the buyer to purchase goods and services. Electronic commerce cannot be realized without strong security procedures which guarantee the buyer and seller that they are transacting in a safe environment where unauthorized users do not interfere with their communication. The primary essence of this thesis is to create a more reliable and efficient security environment for the electronic market in general and specifically for the Business-to-Business kind of commerce. Various researches are made e-commerce security using Symmetric and Asymmetric cryptographic algorithms, but only a few papers were done on reducing the execution time of the algorithm without compromising the strength of security. This thesis was done to fill the gap in reducing the execution time of the AES algorithm from 10 iteration rounds to 8. There were no papers done on this aspect and this thesis use the standard AES algorithm and reduced the number of iteration from 10 to 8 to avoid the limitation of the AES algorithm on the key exchange between the sender and receiver by decrypting the encryption key using the MD5 hashing algorithm to ensure more security. This thesis employed experimental research methods and measured the execution time of the standard AES algorithm and the MRRA algorithm on selected sample files of Text, PDF, and Audio files of 100KB and 1MB using Java crypto until the result indicates that the MRRA reduced the execution time of the standard AES algorithm by 4%.
