Abstract – In online business shoppers must feel completely assured that their credit card and banking details are secure and cannot be accessed by hackers. SET (Secure Electronic Transaction) was developed to fill this need and to basically guarantee payment transactions, from the shopper’s desktop to the merchant’s website and on to the banking gateway. 3D-Secure protocol was designed to be an additional security layer for online credit and debit card transactions; it is an XML-based protocol. SSL (Secure Socket Layer) and TLS (Transport Layer Security) on the other hand, was designed to provide secure communications over the internet, not secure financial transactions. The 3D-Secure protocol uses XML messages sent over SSL/TLS connections with client authentication
