2. Part-I
Introduction to NFC
Contactless Smart Cards
NFC and Secure Element
Management of SE

3. Near Field Communication
 NFC is a short range high frequency wireless communication technology
using the Principle of Inductive coupling.
 NFC is as easy as…. … a touch
 NFC is mainly aimed for mobile or handheld devices.
 NFC is an extension of Radio frequency identification or RFID technology
 Compatible to ISO14443 (Mifare, Felica)

4. NFC OPERATING MODES

5. Applications of NFC

6. No more contactless SMART CARDS NOW!!!
NFC Handset = Contactless Smartcards
Payment
Ticketing
Loyalty
Benefits of NFC Handset
Display to view Card Content
OTA Transactions
JSR 177: Secure Applications and
Trust Services API
The application on the contactless Smartcard is only a
piece of software.
Why always change/reissue the whole card, if changing
the software would do?

7. NFC and the Secure Element
 Dynamic environment for programs and data
 SE can be accessed through
 Host Controller (internal)
 RF Field (external)
 NFC device/SE as a proxy for
PAN-WAN communication
 Questions are
 How to implement SE?
 Who manages/wants to
manage SE (and makes extra revenue)?

8. Implementation of SE
SIM Card
 Business of/Belongs to the Operator
 No contribution to BOM of handset (SIM more expensive)
 “NFC” SIMs can be used in “non-NFC” handsets
Secure Memory Cards
 Card belongs to consumer
 Increase in BOM (card reader required in every phone)
Additional Smartcard Chip (integrated in Handset)
 Handset belongs to consumer
 Increase in BOM (cost for smartcard chip)

9. Management of SE
 Management of SE itself (“Issuer”)
 Mobile Network Operator
 Bank/Credit Card Company
 Handset Manufacturer (integrated IC)
 Trusted 3rd Party
 Government
 Consumer
 Management of Data in SE (“Application/Content provider”)
 Instances above and …
 (Public) Transport Operators
 Merchants using SE as Loyalty card
 Event & Ticket Offices
 … many more
Secure Element/Data/Apps Must NEVER Leave Chain Of
Trust!

10. Part-II
 Processes in NFC structure
Integration of NFC
J2ME
•Security and Trust Services API
•Contactless Communication API
SAT
 Application Management of
SE
J2ME Client
SAT
Benefits of SAT
Conclusion

11. NFC ECOSYSTEM
Personalization
 Setup of Security Domains
 Upload of Applications OTA
 Application Sharing
 Upload of Content OTA
 Download Content over RF

12. Implementation Of NFC
Java Platform2 Micro Edition
[J2ME Client]
SIM Application Toolkit [SAT]
 Communication through
APDUs.
 JSR177 & JSR257 provides full
control over NFC
functionality and access to
SE.
 J2ME depends on mobile
device OS ,interface and API.
 Communication through Java
Card Applets.
 SAT – interface between SIM
card and Mobile Equipment.
 SAT depends on SIM
applications instead of
mobile device OS.

13. The SIM as the SE
 GSMA specifies protocol/interface
for the SIM to be used with NFC
 Chips: SWP (Single Wire Protocol)
 SIM Card is the cheapest solutions
for the SE in regard to BOM
 SIM Card is less often changed than
handset SIM Card is upgraded in value.
 SIM Card is likely to be the SE
for future Handsets
This does not exclude other parties than the MNO to manage the SE, but
MNO is likely to be the manager of the SIM/SE

14. Secure Element Communication in NFC Devices

15. Application Management of NFC
Approach 1:
Send SMS to handset
 J2ME Application starts &
establishes a data connection
 Load data & applications into
SE
 J2ME application only proxy
Problems
 J2ME can be removed by user
 Process of Transaction can be
stopped by user
 J2ME Platform differs from
phone to phone
J2me solution

16. Approach 2:
SIM Card -> Smartcard with
Java Card OS
 SAT is also an extension for
Java Card
Can make use of data bearers
of the handset (SMS,
GSM,GPRS, BT, IrDA …)
 Management Application
already integrated in SE
BIP (Bearer independent
protocol) needs to be defined.
SIM Application Toolkit

17. Benefits of SIMApplication Toolkit
 Closed Systems – Everything runs on SIM/Secure
Environment
 SIM/JCOP is Standardized Development Platform
 Exchange of handset does not effect application
 Independent from Handset Operating System
 Possibility of OTA Management of Apps (hidden to user)
 Basic operation without battery (good or bad?)
 Issues:
 GUI not as sophisticated as in J2ME (Usability)
 Change of the MNO causes work/trouble => applications need to be
moved to different SIM Card

18. NFC roles and actors

19. Service Request
Whether using S/W client or BIP, ME has to set up the IP
connection.
Ways to implement this are:
PULL Mechanism:-
User initiate the request.
PUSH Mechanism:-
Network initiate the request.
Necessary for Remote Transactions.

20. Business Case - Costs
MNO need to operate trust centers for application
management
Bigger/New SIM Cards (need to support
communication with NFC Chip and SAT)
Process of issuing new/changing SIM Cards (every
consumer needs a new SIM)
Move data from old to new SIM (customer service)

21. Conclusions
MNO leases space on the SIM.
In case of lose or theft the SE element could be
deactivated remotely
SAT allows simple & reliable remote management of
Applications
NFC intuitive and easy to use technology for proximity
transactions
