ARIN has implemented PGP (Pretty Good Privacy) as a method to secure 
template transactions sent to ARIN when managing Internet number 
resources. This is in response to a 14 June 2007 directive from the 
Board of Trustees 

Cryptographic signing enables more secure communication between ARIN and 
its customers. In addition to PGP, ARIN offers X.509 certificates as a 
method of cryptographic authentication.  A wide variety of mail and 
signing software exists; ARIN encourages its customers to examine their 
mail software for PGP and X.509 support.  While there are a few known 
issues with some mail user agent (MUA) implementations of PGP and X.509 
standards, ARIN will work with its customers to provide additional 
processing support when needed.

ARIN will also continue to support Mail-From as an authentication 
method, though it is not as secure as digitally signed transactions.

For more details on cryptographic authentication at ARIN, including 
information on using PGP and X.509 certificates with ARIN, please visit: 

If you have any questions regarding PGP or X.509 certificates, please 
contact Registration Services at hostmaster at arin.net or +1.703.227.0660.
