)(/span)ALDN(/a)) today announced it added enhanced security features
to the HASP software protection, anti-piracy and software licensing
tool.

All HASP (Hardware Against Software Piracy) customers now benefit
from an upgraded Win32 Envelope, one of Aladdin's continued efforts to
remain several steps ahead of security threats. Aladdin periodically
improves the security level within its award-winning hardware and
software tools. The updated Envelope features an automatic wrapping
tool that improves anti-debugging features. Accompanying the
enhancement is a new feature that optimizes network utilization by
revoking licenses that are not in use for an extended duration.

"We continually hear from our readers that securing their
code is a never-ending process," said Tim Trickett, publisher of
Dr. Dobb's Journal, the leading journal for software developers.
"To counter new emerging threats, security tools must be
constantly evaluated, reinforced and strengthened."

"Constantly updating our time-tested technology, Aladdin is
committed to maintaining the strong security within the HASP
solution," said Avi Barir, vice president of software digital
rights management at Aladdin Knowledge Systems. "These
enhancements are yet more examples of our commitment to remain leaders
in the software security market."
