SMART CARD SECURITY

2. introduction
Smart card is a 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 Smart Cards
• 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 application area’s
• Government
• E-commerce
• E-banking
• Education
• Office
• Communication
• Entertainment
• Retail
• Transportation
• Health care

14. Basic smart card security 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
 Smart cards 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 .

16. Smart card attacks
Internal
Attacks
Side
Channel
Attacks
Logical Attacks

17. Internal attack
• Alarm (sensors)
– light
– active grid
• Hide
– feature size
– multi-layer
• Confuse
– glue logic
– redundant logic

18. Logical attacks
Communication
Command scan
File system 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 chip is 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 accuracy of 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 card is 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
