Abstract
A method for analyzing a traffic of encrypted packet data sent over a Packet Core Network (PCN) and a traffic analysis device are provided. The method utilizes a traffic analysis device for listening to the traffic of encrypted packet data. The method further authenticates the traffic analysis device with at least one packet data node of the PCN, and sends a code from the at least one packet data node to the traffic analysis device for allowing decryption of the encrypted packet data at the traffic analysis device. The traffic analysis device analyzes the decrypted packet data. Afterwards, the method utilizes the traffic analysis device for separating instrumentation and a packet data node function for at least one packet data node.
Claims10
A method for analyzing a traffic of encrypted packet data sent over a Packet Core Network (PCN), the method comprising steps of:
- listening to the traffic of encrypted packet data at a traffic analysis device;
- authenticating the traffic analysis device with at least one packet data node of the PCN, the at least one packet data node being capable of decrypting the encrypted packet data;
- sending a code from the at least one packet data node to the traffic analysis device;
- storing the received code at the traffic analysis device;
- decrypting at the traffic analysis device the encrypted packet data using the stored code;
- and
- analyzing the decrypted packet data.
