DKIM fights phishing and e-mail forgery

By Miles Libbey

E-mail fraud is a global problem that plagues consumers and
businesses, costing millions of dollars in direct losses,
technology expenditures, lost productivity and network downtime.
With phishing attacks on the rise, leading companies are working
to develop e-mail authentication protocols that protect users
from e-mail fraud.

DomainKeys Identified Mail (DKIM) is an e-mail authentication
proposal that strengthens user protection from e-mail forgery,
and increases accountability for spam and phishing scams. DKIM
defines a domain-level authentication framework for e-mail using
public key cryptography and key server technology to permit
verification of the source and contents of messages by mail
transport agents or mail user agents. The goal of this framework
is to prove and protect message sender identity and the
integrity of the messages they convey, while retaining the
functionality of Internet e-mail as it's known today.

The specification merges Yahoo's DomainKeys and Cisco's Internet
Identified Mail e-mail verification technologies, which have
similar attributes. Cisco and Yahoo submitted the combined
technology to IETF last month
<http://www.networkworld.com/news/2005/071105-yahoo-cisco.html>
for consideration as an e-mail industry standard and to help
enable industry-wide adoption of the technology.

DKIM uses public key cryptography to let users verify and
maintain message integrity, and identifies legitimate messages.
The proposed standard uses DNS in the same manner as DomainKeys,
Yahoo's anti-spam protocol, which is in use around the world.
DKIM also leverages Cisco's Internet Identified Mail
header-signing technology, ensuring signature consistency as
messages are sent through networks.
