        Re: Hewlett-Packard's Intentions to Grant Licenses Related to "IEEE 
P1363: Standard Specifications for Public Key Cryptography"

Dear Dr. Kaliski:

This letter confirms Hewlett-Packard Company's patent licensing policy with 
respect to now-pending patent applications potentially covering the 
above-referenced standard.

To the extent that subject matter covered by the claims of these 
applications is specifically called for by the "IEEE P1363: Standard 
Specifications for Public Key Cryptography," Hewlett-Packard Company will, 
for implementations of that standard, offer licenses under patents that 
issue from these applications and their foreign counterparts.  
Hewlett-Packard Company will offer such licenses on a reasonable and 
non-discriminatory basis to those intending to make, have made, use or sell 
products that are compliant with that standard. 

The only relevant patent application, entitled "Compression and 
Decompression of Elliptic Curve Data Points," is presently pending.  
Currently, there are no plans to file any foreign counterpart applications.

You are hereby authorized to convey this understanding to other members of 
the IEEE P1363 working group and to the public in general.

                                                Yours truly yours,
                                                HEWLETT-PACKARD COMPANY
