Securing Email with Certificates
The globalization of the Internet means that communication between
individuals and online organizations, as well as between individuals
themselves, is largely by email. Unprotected emails can be easily
intercepted and their contents read and/or altered. The securing of
email messages has therefore become an important part of
safeguarding an organization’s digital assets.
Certificates provide the facility to protect incoming and outgoing
email with digital signatures and encryption:
Digital signatures allow verification of the sender’s identity, and
provide proof that the message has not changed after being signed.
Encryption protects the contents of messages by transforming plain
text into unreadable form. Only the authorized recipient can
decrypt the message.
With the certificates and keys stored safely on an eToken, the security
of the organization’s email is assured.
Digitally Signing Email
The first stage in securing your email messages is to digitally sign
your messages using certificates. Digital signatures implement three
important security principles:
Verification: When a person sends an email that has been digitally
signed, the recipient can immediately authenticate the identity of
the sender.
Non-repudiation: The sender cannot deny that he or she is the
originator of the email.
Integrity of content: Adding a digital signature to the email
ensures that any subsequent changes to the content of the message
are immediately detected. Digitally signing an email does not
change the actual message content in any way.
Netscape Messenger, Microsoft Outlook and Outlook Express enable
you to sign individual messages. By configuring the email security
options, you can automatically sign all outgoing emails.
The private key held in the certificate is required to sign an email.
When the email is sent to the recipient, a copy of the sender’s
certificate and its corresponding public key are sent with it.
