PA-SET: Privacy-aware SET protocol
Ayman Abdel-Hamid, Osama Mohamed Badawy, Shreif Bahaa · 2012
E-payment is considered a cornerstone in daily e-transactions. There are many proposed e-payment protocols but the majority of such protocols were designed just to satisfy the traditional flow of payment data which increases the users' risk because of security vulnerabilities and privacy leakage. The Secure Electronic Transaction protocol (SET), a de facto standard, is limited in application due to computation overhead and privacy leakage. In this paper, a new privacy-aware SET enhancement is proposed. The SET protocol is enhanced by hiding the payer's identity and providing transaction privacy during the whole e-payment process. Privacy protection is achieved for the payer while incurring acceptable overhead as demonstrated by performance evaluation experiments.
