    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: At the Transport mechanism level (or Network level) A the Data exchange level (Ciphering the data content)

    4. BGAN network: Built-in protection (1) Position report public key encrypted, 640 bit key, RSAES-OAEPPosition report public key encrypted, 640 bit key, RSAES-OAEP

    5. BGAN network: Built-in protection (2) Position report public key encrypted, 640 bit key, RSAES-OAEPPosition report public key encrypted, 640 bit key, RSAES-OAEP

    6. BGAN network: Built-in protection (3) Position report public key encrypted, 640 bit key, RSAES-OAEPPosition report public key encrypted, 640 bit key, RSAES-OAEP

    7. BGAN network: Built-in protection (4) Position report public key encrypted, 640 bit key, RSAES-OAEPPosition report public key encrypted, 640 bit key, RSAES-OAEP

    8. BGAN network: Built-in protection (5)

    9. Protecting the content over IP networks

    10. Protecting the content over circuit-switched

    11. Focus on encryption devices 64Kb Circuit Switched Data - 3.1Khz Audio STU-III Motorola/ATT/GE Sectera Wireline (FNBDT/PSTN) General Dynamics OmniXi L3 STE (via STU interface) L3 Circuit Switched Data - ISDN UDI/RDI STE L3 KIV-7 Mykotronics OmniXi L3 Brent, Brent 2, Hannibal, Thamer Packet Switched Services DC2K IP Encryptor Thales KG-175 Taclane Classic General Dynamics KG-235 Sectera INE General Dynamics KG-250 AltaSec ViaSat 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

    13. Preliminary results(i)

    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 (200 - 600 km diameter)

    18. Solution disable position reporting

    19. Secure voice over 32kbps streaming IP BGAN Service

    20. 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.
