LOS ANGELES, California (Reuters) -- Internet services company Yahoo Inc.
Friday said it is working on technology to combat e-mail spam by changing
the way the Internet works to require authentication of a message's sender.

Yahoo said its "Domain Keys" software, which it hopes to launch in 2004,
will be made available freely to the developers of the Web's major
open-source e-mail software and systems.

[...]

Under Yahoo's new architecture, a system sending an e-mail message would
embed a secure, private key in a message header. The receiving system would
check the Internet's Domain Name System for the public key registered to the
sending domain.

If the public key is able to decrypt the private key embedded in the
message, then the e-mail is considered authentic and can be delivered. If
not, then the message is assumed not to be an authentic one from the sender
and is blocked.
