The frequency spectrum for the clearing up

The direct coupling to cables and lines presupposes by the attacker, this he has a direct access to the information leading cable and lines.

From the past some cases of this type have been confessed. Today, how far this very effective method still is used, the "third parties" as a rule remain silent about it.

Therefore five cases shall exemplary be looked.

1st example

During the occupation Norway by German troops the available message means of Norway were also used. Between Norway and Sweden as well as Denmark normal relations were insisted historically, too, since the message nets formed so. So the German armed forces used communication links from Norway to Germany. This current way also was led over a Swedish territory, however.
The correspondence was carried out with a new encryption equipment, this one under a later name T having been confessed...or secret author. This encoded message traffic was a very interesting find. It turned out well Swedish scientist so that put the "German secret author" the bases for the deciphering. This work was continued successfully in the British decoding centre. To this the publications read.

2nd example

There existed a very high information need on the two sides during the time of the "cold war". Both sides had concentrated her corresponding potential in Germany.
What did not seem more reasonable to use Berlin as the possibilities of the bipartite town which had a uniform communication system there? So a tunnel was driven first under the sec fool limit then by the Americans. It, an "important communication cable" between the Soviet armed forces administration in Berlin and the Soviet headquarters in Wünsdorf, was aim. The latter place was for the view of the German military leadership in the 2nd World War.

The coupling to the cable was carried out with very good quality. Whether the coupling was measurable is not known.

Action was pre-certainly only a short life but this. Through clearing up of the "glorious five" this project became known to the Soviet news service then.

There is a whole number of detailed literature to this aspect.
