Abstract
The invention claims a spoofing preventing method in a telecommunication system said telecommunication system comprising a terminal for transmitting data packets and at least one node for receiving and forwarding data packets in the first subsystem the method comprises the following steps: in the first subsystem to activate a packet data address of the said terminal used to transmit data grouping between said terminal and the second subsystem the packet data address is stored in at least one node of said first subsystem. the packet data address of the data packet sent through said node routing in the node receiving the packet transmitted by the terminal the packet including a destination address and source address wherein in the node checks whether the source address of grouping the same as the grouping data address and only when the two addresses are the same transmitting the packet to said destination address from said node.
In a packet radio network a packet data address is activated for a terminal for transmitting data packets between the terminal and an external network. Information on the activated packet data address is stored at least in the edge nodes of the network. To prevent spoofing i.e. misrepresentation of sender data the method and network node of the invention comprise checking (206) in the node whether the source address of the packet transmitted from the terminal is the same as the packet data address used in the transmission of the packet or does the source address belong to a set of allowed packet data addresses. The packet is transmitted (207) from the node towards the destination address only if the addresses are identical or the source address belongs to the set of allowed packet data addresses.
