Smart Card Security
Smart cards are small, secure devices containing microprocessors or memory chips that provide cryptographic services and data protection. Their applications span across various sectors including government, e-commerce, and healthcare. Despite their advantages in security and convenience, smart cards face challenges such as potential liability issues if lost or stolen and the risk of hacking.

- 2. introduction Smart card isa small plastic that is embedded with either a microprocessor or a memory chip. provides cryptographic services (e.g. authentication, confidentiality, integrity) is small and personal is a secure device
- 3. History of SmartCards • In the early 1950s Diners club produced the first all-plastic card to be used for payment applications. • Smart card has its origin in 1970s by inventors from Germany, Japan and France. • First mass use was for payment in french payphones. • The manufacturer of Smart Cards are Gemplus, IBM, Siemens, Telesec and many more.
- 4. What is ‘Smart’about the Smart Cards..?? • Smart Cards are capable of not just storing data but also have processing power. • The data stored can be protected against unauthorized access and tempering. • They are appropriate for secure and convenient data storage. • Smart cards have the property of multifunctionality.
- 5. Smart card applicationarea’s • Government • E-commerce • E-banking • Education • Office • Communication • Entertainment • Retail • Transportation • Health care

- 8. What’s inside asmart card ? microprocessor serial i/o interface security logic serial i/o interface: contact to the outside world
- 9. What’s inside asmart card ? test logic serial i/o interface security logic test logic: self-test proceduresmicroprocessor
- 10. What’s inside asmart card ? test logic ROM serial i/o interface security logic ROM: – card operating system – self-test procedures – typically 16 kbytes – future 32/64 kbytes microprocessor
- 11. What’s inside asmart card ? RAM test logic ROM serial i/o interface security logic RAM: ‘scratch pad’ of the processor typically 512 bytes future 1 kbyte microprocessor
- 12. What’s inside asmart card ? RAM test logic ROM EEPROM serial i/o interface security logic EEPROM: –cryptographic keys –PIN code –biometric template –balance –application code –typically 8 kbytes –future 32 kbytes microprocessor
- 13. What’s inside asmart card ? RAM test logic ROM EEPROM serial i/o interface security logic databus databus: connection between elements of the chip. 8 or 16 bits wide microprocessor
- 14. Basic smart cardsecurity features Hardware • closed package • memory encapsulation • security logic (sensors) • cryptographic coprocessors and random generator Software • decoupling applications and operating system • restricted file access • life cycle control • various cryptographic algorithms and protocols
- 15. Cryptographic algorithms Smartcards and intelligent token uses different types of encryption systems. SHA-1, RSA, DES • DES was published by the National Bureau of Standards. It is a secret Key cryptographic algorithm .

- 17. Internal attack • Alarm(sensors) – light – active grid • Hide – feature size – multi-layer • Confuse – glue logic – redundant logic
- 18. Logical attacks Communication Command scan Filesystem scan Invalid / inopportune requests Crypt-analysis and protocol abuse
- 19. Side channel attack •Signal analysis – reduce processor signal by balancing or equalising the power and/or shielding the emission – variable ordering of processes – retry counters • Signal insertion – use sensors for supply voltage, light and temperature – double implementation path (for verification) – check for runtime parameter validity
- 20. Advantages • A chipis tamper resistant. • Information stored on the card can be PIN protected and read write protected. • Capable of performing data encryption. • Capable of processing information.
- 21. Disadvantages • The accuracyof information is small. • It gives liability issues if stolen or lost. • It is potential for too much data on one card if lost or stolen. • It is a potential area for computer hacker and computer viruses. • Lack of technology to support user.
- 22. Conclusions • Smart cardis an excellent technology to secure storage and authentication • Smart card technology is emerging, applications are everywhere • Smart cards enhance service and security • Perfect security does not exist, even not for smart cards • A smart world is the future
