-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 Thanks, Michael. > Microsoft has a policy of avoiding patent searches, not reading > patents, not commenting on patents etc, so they have not been > particularly helpful. Of course it's going to be bloody hard for us to evaluate if curve proposals are securely, simply and efficiently implementable on grounds of IP1 and especially IP2 without checking the patent status of ladders securely, simply and efficiently implementing them. Being fair, Microsoft is far from a monolithic entity. Different employees act differently. Some have been wonderful, friendly and helpful. Some have been… less so. For example, I find it incredibly hard to square the statements (from the same person, Ben Black) that they went through "weeks of addition review to ensure ECCLib [was] released under APL2" - yet somehow were unaware of even their own company's patents in the same field (notwithstanding they were apparently from MSR China)? Kindly explain. I note the palpable irony of a few people sensibly investigating if there's something up the sleeves of those introducing curves _named_ "Nothing Up My Sleeves", and meeting resistance. We are waiting on a response from Legal (which has been chased). Perhaps that will clarify matters regarding that patent in particular, and any others which Microsoft hold or know about. - -- /akr -----BEGIN PGP SIGNATURE----- iQIcBAEBCgAGBQJUGTLDAAoJEOyEjtkWi2t6/kkP/A/tC91G6XUzOWSl7inhWJqD D1zS1zPph05BJewDUqZaBz8FcySzc7/POBw0JQTfNJSshuFUfQerKijCVSTiarEp ODkrXgy+QImG3+tbogzdcZkVL9MVpRE4mbWG66Y3T+uDNGpStmvDAUaRGoPXfjt0 LnHXa2WoeDTdW0uAOUa8wHPzBdiZmCzFbIs5HLxyrcwE1Q4WSXTLolLh7X3xwN+F 3CV75yFFll3hfx13FVvdeZIlHpIwGI7woeRh4AJ3d7nxn828wYDmYc9XfqYGVCxl 4t3WSDiSH5XQde+L1ZOmCIQ5ljoVXmgbOQv3+pTYjWdPfGGECGh5FDidYKvDKoIh s9M0mfU5tcympf+Gzua6dVkWLT8GBUjgAzep0nurX+i4zSExskftj/sO/GNymH0x hNuHP2k5q7ettlywioYnwOdZ1gsEvd2TkVQ/Xe0UHdpcSvyFUM/jCL/bATvLlNX6 0cQFgnC/0yc4d9r6KEQZT5Xo33vrJ2P9IddtcWdiUMieJhI0uukrKEeEMSF2M68g 1Os6T8CnBJ5ncV9mA1jLTYEDM8A1r+JccqI9LplK+U70iwSJ2qLEX0EWOyWRntSu UQGsumQOhm2RO50Tpjw8M3oqFypO/cBYDGla/FlZQjwxcxkIWCYR407p29gPh08Y iBcnDfLWChZVWGjLPKL6 =fMvF -----END PGP SIGNATURE-----
