Netscape. A user may optionally choose to encrypt or digitally sign the message or
even a combination of encryption and signature. The message is then delivered via
the internet to Bank’s mail server.
The OmniMessaging POP client retrieves these messages from the remote (Lotus,
Exchange, Hotmail etc) Mail server and securely stores these messages in the
OmniMessaging Message Store.
The business application requests for new messages via a published interface. The
ZLEMail adapter extracts the message and passes it to the Business Application. The
message is first decrypted and the digital signature verified for authenticity.
There are times when the business application needs to send a secure message / file
to the end user. This can be achieved using the published interface to send emails.
The ZLEMail adaptor will digitally sign and encrypt the message using the
organizations digital certificate.
The OmniMessaging MTA will relay the message to the Lotus mail server. The
message is fully encrypted and secure during transit and can only be decrypted by
the user for whom it is intended. The mail server will deliver these messages over
the internet to the destination users’ mailbox.
Benefits of this approach
• Secure transport of messages and attachments using simple inexpensive
methods
• High Level of security using industry standard Public Key Infrastructure
• Very secure and yet very inexpensive to implement
• Support for large message size and attachments
The user certificates and organization certificates are stored on the NonStop server
for security and fast access. The entire encryption / decryption is performed using
the industry’s most secure hardware devices built by the HP Atalla Division. The HP
Atalla devices support 3DES encryption standards, are tamper proof and prevent
electro magnetic hacking, vibrations etc to ensure that Bank’s private certificate is
100% safe.
