« Crypto-PAn is a  cyrptography-based sanitization tool for network trace owners to anonymize the IP addresses in their traces in a prefix-preserving manner.  Crypto-PAn has the following properties:

   One-to-one  The mapping from original IP addresses to anonymized IP addresses is one-to-one.

   Prefix-preserving    In  Cyrpto-PAn, the IP address anonymization is prefix-preserving. That is, if two original IP addresses share a k-bit  prefix, their anonymized mappings will also share a  k-bit prefix.

   Consistent across traces Crypto-PAn allows multiple traces to be sanitized in a consistent way, over time and across locations.  That is, the same IP address in different traces is anonymized to the same address, even though the traces might be sanitized separately at different time and/or at different locations.

   Cryptography-based    To sanitize traces, trace owners provide Crypto-PAn a secret key.  Anonymization consistency across multiple traces  is achieved by the use of the same key.  The construction of Crypto-PAn preserves the secrecy of the key and the (pseudo)randomness of the mapping from an original IP address to its anonymized counterpart. »
