SHRUG-anon 1.0.1

No project description provided

SHRUG is a simple Python library that lets users anonymize source and destination IP addresses in packet traces. As of the current release, SHRUG supports the following anonymization algorithms:

1. Randomizer algorithm (randomizer)
2. Prefix Preserving algorithm (prefAnon) [Using CryptoPAn]
3. BlackMarker algorithm (blackMarker)
4. Permutation algorithm (permutation)
5. Truncation algorithm (truncation)
6. Reverse Truncation algorithm (revTruncation)

Usage

• Install the package using pip

pip install SHRUG-anon

• Import the module and the anonymization methods

>>> from SHRUG_anon import anonalgos

• The read_from method can be used to read a .pcap or .tcpdump file

>>> input_pks = anonalgos.read_from("/path/to/pcap/tcpdump/file")

• Use one of the six anonymization algorithms on the packet capture stored in the previous step, and store the anonymized packets.

>>> anonalgos.randomizer(input_pks)
>>> anonalgos.write_to("/path/to/anonymized/packets/.pcap/.tcpdump")

• NOTE: The truncation and reverse truncation algorithms require a second parameter, i.e., the number of bits to be truncated.

>>> anonalgos.truncation(input_pks, 12)
