Presentation on smart cards

1. Everything you always wanted to
know about Smart Cards...

2. Smart card
• Integrated circuit card
• Used for personal identification, authentication , data storage.

3. Types of Smart Card
• RSA :- Ron Rivest and Adi Shamir
• ECC :- Elliptic-Curve Cryptography
• AES :- Advanced Encryption Standard

4. Contact Card
•Setup wired connection between Card and Card Reader
•APPLICATIONS:-

5. Contactless Card
Internal Structure
•Contains Embedded Chip connected with Antenna.

6. How Smart Card get Power
Contact Smart CardCards do not contain Batteries Inside it.
Contact Pads

7. How Smart Card get Power
Contactless Smart Card
• Electromagnetic Field
• Generally 10 Cm.
• Distance increases
with Frequency

RAM-for fast computation
EEPROM- Its content are
not lost when power is off.
Databus- Connection
between elements of chip

10. Communication Process
1. Card reader can perform read or write functions on smart card.
2. Card Reader and Smart Card will communicate according to
transmission protocol.
3. Communication channel :- Half Duplex
4. Response data will send to the Server by using ETHERNET.
5. Application Protocol Data Unit

11. What are the threats ?
Confidentiality: unauthorized disclosuredisclosure of information
Integrity: unauthorized modificationmodification of information
Authenticity: unauthorized useuse of service
sender receiver

12. Objective of cryptography
• Giving trust in:
– authenticity of message and/or sender
– integrity of message
– (sometimes) confidentiality of message
• by using an algorithm based on a secret shared
between participants in a scheme.

13. Cryptographic services

15. Conclusions
• Smart card technology is emerging, applications are
everywhere
• Smart cards enhance service and security
• Perfect security does not exist, even not for smart cards
• Risk analysis is essential
