4 | 10 | laforge | This project aims at practical research and experimentation with the [wiki:TETRA] |
5 | trunked radio system. |
||
6 | 1 | ||
7 | 10 | laforge | It is part of the bigger family of [http://osmocom.org/ Osmocom] projects, |
8 | all aiming to create Free Software (Open Source Software) for mobile communications. |

14 | 10 | laforge | The [wiki:osmo-tetra] project aims at implementing the sending and |
15 | receiving part of the TETRA MAC/PHY layer. |
||
16 | 7 | laforge | |
17 | 10 | laforge | Currently, it can |
18 | * receive, demodulate and decode TETRA downlink signals of real-world TETRA networks |
||
19 | * display information about SYNC, SYSINFO, MM and CMCE PDUs |
||
20 | * forward those TETRA downlink signals to the [http://wireshark.org/ wireshark] protocol analyzer |
||
21 | * forward IP packets contained in TETRA SNDCP to a local {{{tun/tap}}} device |

23 | 10 | laforge | == Research on Motorola Dimetra EBTS == |
24 | 2 | laforge | |
25 | 10 | laforge | We are currently investigating the hardware and software architecture of the [wiki:Dimetra_EBTS Motorola Dimetra EBTS], |
26 | including its components like Base Radio, Site Controller, etc. |
||
27 | 2 | laforge | |
28 | 10 | laforge | The goal here is to run this equipment without a Motorla SwMI and thus have an inexpensive platform for running |
29 | your own TETRA network for research purpose. |

31 | 10 | laforge | == Applied Research on security of real-world TETRA networks == |
32 | 2 | laforge | |
33 | 10 | laforge | Using the tools we develop, we are analyzing the security of real-world TETRA networks. |
34 | 2 | laforge | |
35 | 10 | laforge | Our experience so far is quite shocking: All the non-government TETRA networks that we |
36 | have encountered use no TETRA encryption at all, i.e. they are subject to very easy |
||
37 | eavesdropping attacks. |
