3 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services Trial Data  Duration: 4 months, May – June and September – October 2008  Set-up: February – April 2008  100 participants:  Each one will receive a SIM with on board services plus the SCWS platform (ORGA), and a subscription (TI).  A small group (10 users) will also receive Windows Mobile (WM) phones, for exploiting the SCWS advanced services.  All other participants will use their own phone.  End-User components:  WM devices will have a pre-loaded SMS client, plus a gateway to interact with the SCWS platform.  Legacy phones will have to download the SMS client from trial servers.

4 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services SIM-based services  User Identification Service: SMS applications will ask SIM for identifying the user.  User Profile Data Management: the personal profile of the user, or a part of it, will be stored and managed on the SIM.  Digital Signature Service: SIM will contain private/public keys pair for the owner and public keys from other entities (e.g. service providers), which can request digital signature validation/generation.  Software Deployment Service: SIM will automatically trigger the download of the SMS client.

5 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services General SIM Services Architecture SCWS Gateway Trial Servers Smart Card Web Server SIM Services Unique User Interface 1.Legacy phones: minimum set of SIM services; the most advanced features will be replicated on phone and remote servers 2.WM phones: a gateway allows access to SCWS and the complete set of SIM services

6 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services User Profile Data Management  Use Cases:  Pre-entering of user data (e.g. in forms)  Management of user passwords to enable single-sign-on service  Selective service discovery  Portability of personal settings  Authenticated user access to personal data

7 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services User Profile Data Management  What data does the personal profile contain?  To be defined in the service specification  Is useful that SMS applications can remember user data?  It will be a tunable feature, and some test will be done to select if use it or not  Is TLS required for exchanging user data with services?  It is not required  How to query SCWS for obtaining user data?  Namespaces plus key/value approach will be adopted

8 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services User Profile Data Management WM phones:  Profile Data Manger will also provide the User Identification Service, responding to Mobile Application requests forwarded by SCWS Legacy phones:  Each time it’s inserted in a new phone, SIM sends the user identity to trial server  Server retrieves the corresponding profile and sends it to the SMS client on the phone  The SMS client stores the user profile permanently

9 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services Digital Signature Service Use Cases:  MEMs signing  MEMs signature validation  Mobile commerce transactions

10 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services Digital Signature Service  MEMs signing should be used for SMS services provided by University Public Administration (e.g. issuing of certificate to the students, etc.) Legacy phones:  Short messages could be used to implement the service  MEMs signing is not feasible (too many data)  Reasonable only if m-commerce services will be present in the trial  SIM Toolkit as User Interface

11 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services Software Deployment Service  Use Cases:  Automatic triggering of the SMS client download

12 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services Software Deployment Service WM phones:  No need to download SMS Client, it will be pre-installed Legacy phones:  IMEI Tracking Application will also provide the User Identification Service: each time the SIM is inserted in a new phone, user identity will be communicated to the server for triggering the user profile download

13 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services Implementation Plan Time schedule:  First Service Specification Release: 30 th November 2007  Final Service Specification Release: 17 th December 2007  Test card for profile test: half of December 2007  Test card for applications test: 29 th February 2008  End of applications test phase: 31 st March 2008  Trial cards release: 30 th April 2008 SIM features:  256KB of memory  Support for cryptographic co-processor and RSA  White card (no art work)

14 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services SIMs and Subscriptions provisioning ORGA will provide:  100 SIM cards  5 WM phones  SIM Card components:  Smart Card Web Server  Profile Data Manager, Data Storage  Digital Signature Service Application, Key/Certificate Storage  IMEI Tracking Application  Phone components:  SCWS Gateway  Server components:  Short Message Gateway Server

15 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services SIMs and Subscriptions provisioning TI commitment:  Provide 100 new pre-paid subscriptions (no number portability)  Activate 100 service cards for the whole trial duration that will grant to each participant a certain amount (500MB/1GB, dependently from the particular service card) of data traffic per month:  TI will offer an initial credit on the pre-paid card to cover the total cost of the service card. Example: 20 Euro/month the service card cost, 4 month the trial duration  80 Euro of initial credit  Each trial month TI will automatically renew the service card subtracting the cost from the pre-paid credit  Users will pay for all data traffic exceeding the per-month limit of the service card  Users will pay for all non-data traffic (voice, SMS, etc.)  Provide 2 WM phones

16 TELECOM ITALIA GROUP Trial at the University of Rome: SIM-based Services User Recruitment  Prepare public announcements (within January)  Define the terms and conditions for trial participation: cell number changing, WM phones treatment, privacy of personal info, tracking activity for reporting purposes, data access constraints, …  Advertise what will be offered:  a GPS receiver  free data access for the whole trial duration  Seminars to students of different faculties in the campus  Encourage groups participation  Use a web site for collecting pre-registrations and users indication:  how they will use the system  references to existing community services on the web
