It has been brought to my attention that UUNET Technologies has a pair of
patents covering network encryption. The patents are very broad, and
basically cover anything that selectively encrypts datagrams based on
source/destination information. This would automatically cover all
implementations of the IPsec protocols.

UUNET's legal staff have stated their intent to begin actively pursuing
these patents, beginning this summer. It is my understanding that their
licensing terms are quite reasonable. However, this patent has (obvious)
implications for everyone here, and so I bring it to your attention.


The patents are:
