1 Government Roadmap Tom Clark Delta Wave Communications, Inc. Broadband for a mobile planet TM

2 BGAN and information assurance

3 Requirements in the government sector Information assurance implies that –The content cannot be altered or intercepted by an uninvited parties. –The confidentiality (identity and location of the end user) is protected –Statistical analysis of the data transfers is prevented Security has to be deployed at two levels to cover these requirements: Network level –At the Transport mechanism level (or Network level) Ciphering the data content –A the Data exchange level (Ciphering the data content)

4 BGAN network: Built-in protection (1) IP Core Network Burum SAS DP POP InternetInternet WWW Server Customer HQ Air Interface  Data and signaling ciphered in accordance with UMTS standards (TS33.102)  Position report encrypted  Temporary IDs used to maintain anonymity of the terminal user (SIM).  Satellite control is US Type-1 Encrypted

5 BGAN network: Built-in protection (2) IP Core Network Burum SAS DP POP InternetInternet WWW Server Customer HQ Satellite Access Station  Joint military/commercial Satellite Earth Stations in the Netherlands and Italy.  Fully Redundant SAS sites  Data communications network protected by firewalls

6 BGAN network: Built-in protection (3) IP Core Network Burum SAS DP POP InternetInternet WWW Server Customer HQ Typical DP PoP Interconnect  Routed over leased lines or VPN over IP networks  Redundancy - backup links: VPN over public IP network or ISDN  Firewall protected  IPSec encryption applied between Inmarsat and DP POPs

7 BGAN network: Built-in protection (4) IP Core Network Burum SAS DP POP InternetInternet WWW Server Customer HQ Typical DP / Customer Interconnect  VPN over IP networks:IPSec encryption  Firewall protected

8 BGAN network: Built-in protection (5) IP Core Network Burum SAS DP POP Customer HQ Leased Line Dedicated DP / Customer Interconnect  Private dedicated links  IP Sec encryption  Firewall protected

9 Protecting the content over IP networks IP Core Network Burum SAS DP POP InternetInternet WWW Server Customer HQ End-to-end Application Layer  COTS VPN (e.g. Cisco, Checkpoint, Nortel, Netscreen)  Government standard encryption including Type-1/Top Secret Leased Line

10 Protecting the content over circuit-switched Circuit Switched Core Network Burum SAS Customer HQ International PSTN/ISDN STU  ISDN Encryption - STE  Serial Bulk Encryption – KIV-7  Analogue Encryption – STU-IIb/III End-to-end Application Layer

11 Focus on encryption devices 64Kb Circuit Switched Data - 3.1Khz Audio STU-IIIMotorola/ATT/GE Sectera Wireline (FNBDT/PSTN)General Dynamics OmniXiL3 STE (via STU interface)L3 Circuit Switched Data - ISDN UDI/RDI STEL3 KIV-7Mykotronics OmniXiL3 Brent, Brent 2, Hannibal, Thamer Packet Switched Services DC2K IP EncryptorThales KG-175 Taclane ClassicGeneral Dynamics KG-235 Sectera INEGeneral Dynamics KG-250 AltaSecViaSat KG-240 Red Eagle L3

12 Interoperability results so far… –Thales DC2K –STU-IIB/III –STE –Viasat KG-250 –Taclane KG-175 –Sectera KG-235 Successfully tested over BGAN

13 Preliminary results (i) Without TCP PEPWith TCP PEP Upload (kbps) Download (kbps) Upload (kbps) Download (kbps) Thales DC2K 109 (ii) 172 (ii) 215 (ii) 252 (ii) Viasat KG (iii) 128 (iii) Not tested Taclane KG (iii) 112 (iii) Not tested (i)FTP transfer of 1MB file, using T&T explorer 500 and LINUX platform; (ii)Throughput averaged over 10 file transfers (iii)Best Throughput observed over 10 file transfers Up to 100% improvement

14 Conclusions Network Security (TRANSEC) –BGAN uses all of the latest Commercial security measures to protect itself against service interception, eavesdropping or statistical analysis from third parties. Content Security (INFOSEC) –Commercial and Government Grade encryption mechanisms have been proven to work over BGAN ensuring end- to-end confidentiality and integrity of the data content.

15 Position reporting in BGAN

16 BGAN - position reporting Why is User Terminal position reporting required? –Regulatory May require that UT position is known when operating in certain jurisdictions –Billing Allows for zone/country based tariffs –Expedites call setup process BGAN UT contains built-in GPS receiver GPS position reported (encrypted) to network as part of registration process Special circumstances mean that important government customers may find this facility an obstacle to purchasing the service

17 Solution – disable position reporting Considerations –Minimum level of UT position reporting for network access is required – spot beam ID –GPS receiver required in UT in order to determine its location and provide optimised operation Solution –Disablement through a SIM feature –UT translates GPS position to a spot beam ID using internal map –Only spot beam ID reported to network UT operates discretely within a spot beam ( km diameter)

18 Solution – disable position reporting Discrete Operation SIM Position Reporting Disabled

19 Secure voice over 32kbps streaming IP BGAN Service

20 Key application for both Civil and Military Government agencies Core Secure Voice traffic is low but stable and expected to remain stable Secure Voice is an enabler for BGAN Sales in Government Sector. Cost and Functionalities scrutinised by Procurement decision makers in that sector Secure Voice over 3.1kHz Audio Channel (64kb/s) does not cater for all markets Need for Cost Effective Secure Voice Solutions over BGAN Secure voice in the government sector

21 Solutions: Technical The 4kbps Voice service cannot be used for encrypted voice Secure Voice over IP is the way forward: The BGAN 32kbps Streaming Class (IP) service can be used as transport mechanism for Encrypted Voice. Example of architecture
