I don't see why we need to tie encryption and spam control together. I
don't even see the first claim you make - why does encryption limit
spam? Are you proposing we send only encrypted email?
Chuck Wegrzyn
There have been a number of proposals on this list that suggest that the
best way to limit SPAM is raise the cost of transmitting an email. In
some cases these proposals are based on a micropayment scheme. Other
systems such as HashCash force the sender to "send" CPU cycles. I am
simply suggesting that since the act of encryption costs CPU cycles, an
encryption system might fulfill many of the same design principles as a
system like Hashcash, while, at the same time providing a privacy service.

Hi all
I have a silly question that didn't seem to be addressed in the FAQ.
I'm trying to understand dependancies between opportunistic encryption
of
email and efforts to control SPAM.
From what I can tell, there are some very significant cross effects
between the two technologies:
First: If email is encrypted, this will sigificantly limit the
locations
at which SPAM control technologies can be deployed.
Second: Encryption is computationally expensive. Potentially, the act
of
forcing end nodes to encrypt an email prior to sending it could
increase
the cost of transmission enough to render many forms of SPAM
economically
unviable. [On a related topic, is their a well accepted boundary
condition regarding the total cost to transmit an email message in
order
that SPAM is economically viable?]
Third, the same key distribution technologies that enable encrypted
email
will also be necessary for any kind of digital signature system.
From my (admittedly novice) perspective, it would appear that SPAM
control
and encryption need to be considered in parallel.
I haven't seen much dicussion of this topic on the mailing list.
