|
4 | |||
5 | |||
6 | This project aims at practical research and experimentation with the [[TETRA]] |
||
7 | 10 | laforge | trunked radio system. |
8 | |||
9 | 22 | It is part of the bigger family of "Osmocom":http://osmocom.org/ projects, |
|
10 | 1 | all aiming to create Free Software (Open Source Software) for mobile communications. |

20 | The [[osmo-tetra]] project aims at implementing the sending and |
||
21 | 7 | laforge | receiving part of the TETRA MAC/PHY layer. |
22 | 1 | ||
23 | 10 | laforge | Currently, it can |
24 | 22 | * receive, demodulate and decode TETRA downlink signals of real-world TETRA networks |
|
25 | * display information about SYNC, SYSINFO, MM and CMCE PDUs |
||
26 | * forward those TETRA downlink signals to the "wireshark":http://wireshark.org/ protocol analyzer |

30 | 22 | h2. Research on Motorola Dimetra EBTS |
|
31 | |||
32 | |||
33 | We are currently investigating the hardware and software architecture of the [[Dimetra_EBTS|Motorola Dimetra EBTS]], |
||
34 | 1 | including its components like Base Radio, Site Controller, etc. |
|
35 | |||
36 | 22 | The goal here is to run this equipment without a Motorla [[SwMI]] and thus have an inexpensive platform for running |
|
37 | 1 | your own TETRA network for research purpose. |

39 | |||
40 | 22 | h2. Applied Research on security of real-world TETRA networks |
|
41 | |||
42 | |||
43 | 1 | Using the tools we develop, we are analyzing the security of real-world TETRA networks. |
|
44 | |||
45 | Our experience so far is quite shocking: All the non-government TETRA networks that we |
||
46 | have encountered use no TETRA encryption at all, i.e. they are subject to very easy |
||
47 | 2 | laforge | eavesdropping attacks. |
