The text of the original IPR declaration:

Received August 3, 2001
From: "Linn, John" 

RSA Security Inc. has submitted a patent application concerning client
puzzles, a technique initially described in Juels and Brainard, "Client
Puzzles: A Cryptographic Countermeasure against Connection Depletion
Attacks", ISOC NDSS, 1999.  Discussions within the IPsec WG have cited this
technique and have considered incorporation of methods with similar
properties, and the client puzzles concept has recently been referenced in
draft-ietf-ipsec-properties-00.txt.  If use of client puzzles is
incorporated into a future IPsec specification, and if the currently active
application leads to an issued patent, RSA Security Inc. is willing to grant
licenses to such patent under reasonable and non-discriminatory terms for
purposes of implementing that IPsec specification. Correspondence concerning
licensing for this technology should be addressed to: RSA Security Inc., 36
Crosby Drive, Bedford, MA  01730, USA, Attn: General Counsel.
