Abstract

This document presents the proposal for a stronger authentication method of the updates of the RIPE database based on digital signatures. The proposal tries to be as general as possible as far as digital signing methods are concerned, however, it concentrates mainly on PGP, as the first method to be implemented. The proposal is the result of the discussions within the RIPE DBSEC Task Force.

1. Rationale

An increasing need has been identified for a stronger authentication of the database maintainer upon database updates (addition, modification and deletion of objects). The existing authentication methods have serious security problems: the MAIL-FROM has the drawback that a mail header is very easy to forge whereas CRYPT-PW is exposed to message interception, since the password is sent unencrypted in the update mail message.

The goal was to implement a digital signature mechanism based on a widely available and deployed technology. The first choice was PGP, other methods may follow at a later date. PGP is presently quite widely used within the Internet community and is available both in and outside the US.

The current aim is for an improved authentication method and nothing more (in particular, this paper does not try to cover authorization issues other than those related to authentication).

2. Changes to the RIPE database

In order to make the database as much self consistent as possible, the key certificates are stored in the RIPE database. For efficiency reasons a local keyring of public keys will also be maintained, however, the local keyring will only contain a copy of the key certificates present in the database. The synchronization of the database with the local keyring will be made as often as possible. The database objects will be created only via the current e-mail mechanism (auto-dbm@ripe.net), in particular no public key certificate will be retrieved from a key server by the database software.

The presence of the key certificates in the database will allow the users of the database to check the "identity" of the maintainer, in the sense that they can query the database for the certificate of the key the database software uses for authenticating the maintainer. This key certificate can then be checked for existing signatures and can possibly be compare...
