Abstract-- Real­world traffic traces are crucial for Inter­
net research, but only a very small percentage of traces col­
lected are made public. One major reason why traffic trace
owners hesitate to make the traces publicly available is the
concern that confidential and private information may be
inferred from the trace. In this paper we focus on the prob­
lem of anonymizing IP addresses in a trace. More specifi­
cally, we are interested in prefix­preserving anonymization
in which the prefix relationship among IP addresses is pre­
served in the anonymized trace, making such a trace us­
able in situations where prefix relationships are important.
The goal of our work is two fold. First, we develop a
cryptography­based, prefix­preserving anonymization tech­
