Procedure and telecommunication network to increase the security in data exchange packet mode

摘要

Process for increasing security in data exchange packet mode according to an Internet Protocol between network nodes of a telecommunications network (100), cooperating for transmitting a data packet Internet Protocol at least a first node network (11) of a first supplier of telecommunication services and a second network node (12), the second network node (12) a neighbor node of the first network node (11), having assigned the first node network (11) identification information, the second network node (12) access to identification information assigned to the first network node (11), the method comprising the following steps: - in a first process step, the first network node (11) added to the data packet Internet Protocol information identifying the first network node (11), - in a second process step the data packet Internet Protocol is transmitted to Segu ndo network node (11), - in a third method step, the second network node (12) performs a check of the data packet of Internet Protocol, the check comprising by the second network node check identification information being the data packet Internet Protocol rejected by the second network node (12) when the identification information data packet Internet Protocol does not match identification information assigned to the first network node ( 11), to which the second network node (12) has access, characterized in that for the transmission of the data packet Internet Protocol cooperates a third network node (13), in addition to the first and second nodes net (12), and because the data packet Internet Protocol includes a skip information that is modified in each transmission node prior to another network node network, recognizing the third network node (13) under the skip information data packet Internet Protocol that checking identification information on the second network node (12) has been satisfactory and transmitting the third network node (13) the data packet Internet Protocol.
