Collecting network traffic traces from deployed networks is one of the basic steps in understanding communication networks. These traces may be used for network management, traffic engineering, packet classification, and for analyzing network behavior to ensure adequate Quality of Service. They may also be used for identifying and tracking network anomalies and formulating responses to maintain network security. For privacy and security reasons, monitored traffic traces should be modified before they may be shared. This is known as a trace anonymization process. The goal of anonymization is to preserve traffic properties while enforcing the privacy policies. Numerous tools and techniques have been implemented for trace anonymization such as Crypto-PAn, Anontool, ip2anonip, Lucent.s extensions to Crypto-PAn, FLAIM, IP-Anonymous, and TCPdprive. These tools use a variety of anonymization algorithms: black-marker, random permutations, truncation, pseudo-anonymization, and prefix-preserving pseudo-anonymization.
The Anonym tool is a MATLAB GUI-based tool that enables anonymization of Internet traffic using six algorithms:
The anonymized output may be compared with the input trace file using one of nine analysis options:
The Anonym tool currently supports traffic traces in PCAP and MRT formats.
The latest revised version of the Anonym tool maybe downloaded here:
AnonymTool_revised.zip.
The software package includes a README file with instructions on how to run the tool.
Anonym tool has been completely tested in a Windows 7 environment using MATLAB 2013a and 2015a.
