Aladdin Announces eToken PKI Support for Linux and MAC OS

CHICAGO, January 18, 2006 - Aladdin Knowledge Systems (Nasdaq:ALDN), the worldwide leader in Software Digital Rights Management (DRM) and USB-based authentication solutions, and a leading innovator in enterprise secure content management (Enterprise Security), today announced general availability of its eToken Middleware for Linux 3.60 and eToken Middleware for MAC OS. This new software enables interaction between the eToken smart card authentication token and computers running on the MAC OS or Linux, and provides full support for secure token-based strong authentication and PKI solutions.

With the new release, Aladdin now provides unparalleled, broad support for organizations that work with the MAC OS and Linux operating systems, enabling them to easily implement secure PKI solutions for MAC OS and Linux users, as well as Windows users.

eToken now supports the following PKI operations on the MAC OS and Linux systems:

• Importing digital certificates to eToken
• Email signing and encryption
• Certificate-based (SSL v3) secure Web authentication
• Certificate-based VPN authentication
• Thin client authentication

PKI keys are securely generated onboard the eToken smart card chip. Security is not compromised because the user's private keys never leave the token. With full support for PKCS#11, eToken can be integrated with any applications running over the PKCS#11 cryptographic module, providing numerous, powerful security capabilities.

"We see a major increase in organizations that use the MAC OS and Linux platforms and are seeking to implement strong authentication security solutions," said Shlomi Yanai, vice president of the Aladdin eToken Business Unit. "Aladdin sees support of the MAC OS and Linux platforms, in addition to our broad support for the Windows environment, as an important strategic initiative that will enable us to expand our business in key markets."
