266 Lotus Security Handbook Message encryption SMTP, with support for the SMTP extensions, can ensure that the initial client-to-server communication has been correctly authenticated. This does not, however, guarantee that during transit every single SMTP hop along the way will use that same authentication. Figure 6-25 Advanced SMTP configuration settings Furthermore, the message itself is not encrypted. This can be solved by using another SMTP extension that ensures the SMTP communications (client/server or server/server) are encrypted using public/private key pairs. However, this again does not guarantee that the message, during transit, will be encrypted for every single SMTP hop all the way to the recipient. Even if it were possible to guarantee that the e-mail message was correctly authenticated with trusted SMTP servers and fully encrypted during its hops along the way from sender to recipient, it still does not avoid the possibility that the message was spoofed from someone else. Thus, the only sure way to provide confidentiality, authentication and integrity of any e-mail message is to make sure that the MIME content of the message is cryptographically manipulated (using different methods for encryption). Until
ecently there were two competing standards for achieving this: PGP and S/MIME. Let’s first discuss PGP. 6.2.8 Secure messaging with PGP PGP, which stands for “Pretty Good Privacy,” is a highly secure public key encryption system designed for sending secure mail anywhere around the world. It was developed by Mike Zimmerman in 1991, and published freely on the Internet. The client and information on PGP can be found at the following URL: http://www.pgp.com/ Also available is GnuPG (Gnu Privacy Guard), which is a complete and free replacement for PGP. Because it does not use the patented IDEA algorithm, it can be used without any restrictions. GnuPG is an RFC2440 (OpenPGP) compliant application. Version 1.0.0 was released on September 7th, 1999. The current stable version is 1.2.2. GnuPG is free software. It can be freely used, modified and distributed under the terms of the GNU General Public License. Information on GPG can be found at the following URL: http://www.gnupg.org/ Information on the GNU General Public License can be found at: http://www.gnu.org/copyleft/gpl.html PGP does not have key management capabilities. In fact, its certificate structure is a very loose one, in which, instead of having authorities issue certificates to individuals, it works on a “web of trust” model, where certificates gain authority by being signed by known and trusted people. A newer standard, called OpenPGP, permits a hierarchical approach to accommodate certificate authorities, X.509 certificates, and other already-accepted standards. More information on OpenPGP is at the following URL: http://www.openpgp.org/ The OpenPGP Message Format is explained in RFC2440, available at: http://www.ietf.org/rfc/rfc2440.txt While PGP has seen some good adoption worldwide, most corporations are keen to implement S/MIME for messaging within and outside of the organization. We <strong>cover</strong> S/MIME in the next section and detail how this works in conjunction with the Lotus Notes client and Lotus Domino server. Chapter 6. Public key infrastructures 267
