ACSP Suggestion 2011.1: Update to support CRYPT-PW and PGP


Author: Jon Lewis   
Submitted On: 11 January 2011

Description: should be updated to support CRYPT-PW (with both DES and md5-crypt) and PGP authentication.

mail-from is too trivial to forge. Due to the fact that the registry would likely make public the encrypted passwords, DES crypt and its 8 character limit makes such passwords trivial to crack using modern computing resources.

MD5-crypt is better, but still vulnerable to brute force cracking since the encrypted password would likely be publicly visible. PGP should be the preferred method of authenticating email-submitted change requests as its the most difficult to forge.

With effectively no security on data, I’m not willing to rely on it for teh purpose of having my transit providers build BGP filters based on the data. Frankly, I’m surprised anyone is using it in its current state.

ARIN will be updating its IRR code to support pgp and crypt-pw authentication. We hope to have these new features ready and available for community use by the end of August 2011.
