Title

Prefix- and Lexicographical-order-preserving IP Address Anonymization

Abstract

The anonymization of SNMP traffic traces requires an IP address anonymization scheme which is prefix-preserving and lexicographical-order-preserving. We present an anonymization scheme satisfying these two requirements which has been derived from the prefix-preserving cryptography-based scheme Crypto-PAn. We show correctness of the scheme and describe an embeddable implementation. Limits of the proposed anonymization scheme and some security aspects will be discussed as well.
