A Security Solution for Bank Card

Abstract

Analyze the management vulnerabilities and technology vulnerabilities of current bank cards firstly, explain the technical features of the magnetic stripe and memory chip bank card, and disclose the method probably used by criminals while attacking. Meanwhile analyze the reasons why PKI may be infeasible to guarantee the security of bank cards. Vertical authentication based security solution for bank cards are proposed. Use CPU smart chip to replace the magnetic stripe card and memory chip. Set up signature and encryption protocols dealing with withdrawal form or payment order on the basis of vertical authentication in CPU smart chips, and replace current withdrawal or payment password authentication protocol. Therefore, set up a chip-level withdrawal or payment system for ATM or POS to guarantee the security of bank card withdrawal or payment.
