FW: Private Communication Technology (PCT) secure channel protocol
This is a repost, it was sent to the wrong alias initially. Note, you
can safely ignore the attachment that comes with this mesage, it is
formatting info only.
========================================
Users of computer networks, and especially users of the Internet,
need trustworthy communication. Microsoft and its partner
Internet companies (currently Netmanage, Spyglass, OpenMarket,
Internet Shopping Network, and Cylink) are releasing the
specification for Private Communication Technology.
PCT is the next step in secure channel protocols. It is backwards
compatible with SSL, and it is an open standard. We hope it will
be accepted by the IETF and other working groups and
interest groups.
PCT is a new, more secure, and more efficient version of the popular
SSL protocol for general purpose secure communication. PCT is
more secure because it fixes several security flaws in SSL,
it has much better assurance that data is delivered correctly,
and it is simpler. It is more efficient because it sends fewer messages
and handles the data more smoothly. It is also more
flexible because more cryptographic parameters can be negotiated.
Because PCT is specified by an open standard and is
compatible with SSL, the industry can easily adopt it.
You can find the specification at
<http://www.microsoft.com/windows/ie/pct.htm>,
or you can follow the PCT link from Microsoft's home page
<http://www.microsoft.com>
to reach the spec and other materials.
