English Abstract

Criminal hackers find a target for their actions in the field of electronic transactions.

Credit card information, bank account passwords, and other personal information is being stolen from Websites that deal with E-commerce.

An ECommerce defense system made from multiple levels of security is needed to fend of these attacks.

Such a strategy sees security of E-commerce as the vital process of detecting the unauthorized use of an organization's ID, Web site, E-mail information and preventing it to defend the company, its employees and customers.

This work proposes secure system to protect E-Commerce application over the Internet and the proposed system is concerned with the following suggestions.

First of all, building immune Website for E-Commerce according to the principles of Web engineering, second, the proposed system builds a huge secure E-commerce and E-bank databases and that is done by encrypting each transaction using the proposed modified Twofish encryption method and each transaction uses different key for encryption in order to increase the security of the proposed system.

The modified Twofish concentration strengthens the MDS by making it dynamic.

The third suggestion which presents the main goal of the proposed designed system is securing channels over the Internet and in order to do that, encrypting the transmitted sensitive data is suggested by the proposed encryption method which depends on modifying the idea of Diffie-Hellman key exchange and completely removing the discrete logarithm and replacing it by irreducible truncated polynomial to overcome the problem of large prime numbers and non-full coverage of the finite set.

Finally, after implementing the proposed system many results are obtained, from these results, the proposed work can be evaluated.

The most important one is that the secure channels become much more reliable and robust from the international standard principles of security and the time expanded in E-Commerce security transactions decrease with the observation of secure agents.
