A5-GMR-1
v4 v5 19 19 And finally keystream is ready to be produced. First for the downlink and then for the uplink. Actual length depends on channel type but for FACCH3 for example you'd produce 96 bits for the downlink direction (Sat -> Phone) and then 96 bits for the uplink direction (Phone -> Sat). Note that the role of uplink and downlink can be reversed when dealing with "Terminal-to-Terminal" calls. 20 20 21 Credits goes to Benedikt Driessen, Ralf Hund, Carsten Willems, Christof Paar, and Thorsten Holz for their reversing work, extracting this from the [ [Thuraya_SO2510]] firmware.21 Credits goes to Benedikt Driessen, Ralf Hund, Carsten Willems, Christof Paar, and Thorsten Holz for their reversing work, extracting this from the [wiki:Thuraya_SO2510] firmware. 22 22 23 23 == Implementation ==
