Dynamic Authentication Challenge-based. The terminal issues a challenge to the card, The card signs the card serial number and this challenge. The terminal verifies this signature. The card must incorporate the public-key encryption functions. The private key is permanently stored in the card and protected by physical security features. Key management issue.

9 Electronic Cashالنقد الالكتروني
Electronic cash is a general term that describes the attempts of several companies to create a value storage and exchange system that operates online in much the same way that government-issued currency operates in the physical world. Concerns about electronic payment methods include: Privacy Security Independence Portability Convenience Muhammad Wasim Raad

10 Electronic Cash Issues
Primary advantage is with purchase of items less than £5 Credit card transaction fees make small purchases unprofitable Facilitates Micropayments – eg for items costing less than £1 Must be anonymous, just like regular currency Safeguards must be in place to prevent counterfeiting Must be independent and freely transferable regardless of nationality or storage mechanism Muhammad Wasim Raad

11 Electronic Cash Muhammad Wasim Raad

12 Electronic Cash Storage
Two methods On-line Individual does not have possession personally of electronic cash Trusted third party, e.g. e-banking, bank holds customers’ cash accounts Off-line Customer holds cash on smart card or electronic wallet Fraud and double spending require tamper-proof encryption Muhammad Wasim Raad

13 Electronic Cash Advantages Disadvantages
Electronic cash transactions are more efficient and less costly than other methods. The distance that an electronic transaction must travel does not affect cost. The fixed cost of hardware to handle electronic cash is nearly zero. Electronic cash does not require that one party have any special authorization. Disadvantages Electronic cash provides no audit trail. Because true electronic cash is not traceable, money laundering is a problem. Electronic cash is susceptible to forgery. So far, electronic cash is a commercial flop. Muhammad Wasim Raad

23 M(obile)-Payments – the future?
“Analysts believe that easy mobile payment is one of the main prerequisites for the success of m-commerce. When the mobile phone can function as an electronic wallet for mobile payments, including micropayments, application developers will find it attractive to introduce new mobile communication services to the market. Examples include mobile entertainment (downloads of music, mobile gambling, etc.), information services (sports news, horoscopes, location-based services, etc.), and real-world services (paying parking fees, buying train or concert tickets, etc.). Network operators envision micropayments as an attractive business that does not compete with banks or credit card companies. For the end user, PayCircle will make m-commerce easy and secure and thus eliminate the major hurdles to widespread adoption and popularity.” Press release Jan 23rd 2002 Muhammad Wasim Raad
