Does anybody have details about the Invisimail product sold by RPK
(http://www.invisimail.com/) ? The abundance of (TM) in their FAQ, the use
of a proprietary algorithm with some suspicious claims of unusual
cleverness, and the lack of source code don't bode well, but one can never
know:
[...]
RPK InvisiMail uses the RPK Encryptonite™ Engine to provide the security for
encryption, authentication and digital signatures. RPK Encryptonite is
strong and secure. Experts believe it to be unbreakable. The RPK
Encryptonite Engine embodies the RPK Fast Public Key encryption algorithm, a
new way of using proven mathematics for fast public key cryptography. RPK is
dramatically faster than the well-known RSA algorithm, yet just as secure.
Based on a new concept called a Mixture Generator™, RPK leverages the same
mathematics behind the widely used Diffie-Hellman Key Exchange to produce a
fast, secure, flexible system. RPK has been analyzed by world class
cryptographers who have issued reports on the security and integrity of the
technology.

19. How does the RPK Fast Public Key Cryptosystem Work?
Rather than using keys to directly transform the data, the RPK patented
Mixture GeneratorTM technology, a combination of long linear feedback shift
registers (LFSR), performs high speed exponentiation using the keys to
synchronize the RPK EncryptoniteTM Engine [hyperlink to Encryptonite engine]
to a randomly generated state. It then uses the high-speed keystream output
of the same engine to encrypt the data. It is these combined techniques,
(explained further in the company’s detailed white papers) [hyperlink to
www.rpk.co.nz], that lead to superior performance.

Combination of LFSR? Hmmmm...
