SANTA MONICA, Calif.--(BUSINESS WIRE)--June 10, 1999--

Trusted and Secured E-Commerce Environment for Malaysia Delivered

by DIGICERT in Partnership With ISOCOR, Fujitsu and iD2 Technologies

ISOCOR (Nasdaq:ICOR), a leading Internet messaging and directory software developer, Thursday announced that it will provide key components of a proposed new e-commerce infrastructure for Malaysia.

The first Malaysian Certification Authority, DIGICERT, will deliver the new service -- a first in Malaysia. It will use a security module from iD2 Technology, an Ericsson associated company, that employs the ISOCOR Global Directory Server (GDS) to store the security keys that users need to encrypt and digitally sign documents.

Fujitsu Computer Systems Malaysia (FCSM), in association with ISOCOR local partner, UTMI, is providing hardware and integration expertise with the aim of bringing the Malaysian economy into the forefront of e-commerce.

"In line with an ongoing strategy of keeping Malaysia in a leadership position in the use of information technology and communications, DIGICERT has been instructed to provide the basis for a Trusted and Secured electronic transaction environment," stated Noor Azli Othman, chief executive officer, Digicert Sdn Bhd.

"The new service will be recognized under Malaysian law, as stipulated under the Digital Signature Act (DSA 1997), and promises to be a vital enabling technology in helping Malaysians to gain maximum benefit from the revolutionary concept of doing business by electronic means such as e-commerce."

"The solution provided by ISOCOR in association with its partners will speed up the evolution of Malaysia in the direction of a fully developed, mature and knowledge-rich society playing a leadership role in the information age," noted Paul Gigg, president and CEO, ISOCOR.

"With values such as privacy, authentication and non-repudiation in place, the Malaysian economy can use electronic media with the same confidence as traditional paper-based transactions, but far more swiftly and efficiently. This can enable massive savings through speedier delivery and just-in-time manufacturing, plus increased revenues by reaching out to global markets."

"The security components provided by iD2 Technologies enable organizations to easily produce, administer and distribute very high volumes of digital certificates," added Bjorn Gustavsson, president of iD2 Technologies. "These certificates are used for applications such as secure identification on the Internet, network security and digital signatures, and used in association with ISOCOR Internet infrastructures will help to make Malaysia a regional and world leader in the adoption of electronic commerce."

The organization with the role of providing the total solution is DIGICERT SDN BHD. As a Certification Authority and trusted third party, DIGICERT will authenticate and certify the identity of persons or organizations that conduct electronic transactions in a multimedia networked environment. It will also produce digital certificates that will enable users to enjoy secured transactions over open networks, without worrying about issues such as confidentiality, integrity, authenticity and non-repudiation.

DIGICERT SDN BHD will manage the life cycle of certificates: creation, storing and revoking. The DIGICERT service offering will include user registration, authentication of identity and attributes, issuing, maintaining and revoking digital certificates for individuals and organizations. The DIGICERT Public Key Infrastructure (PKI) solution combines the best-of-breed technologies -- ISOCOR and iD2 Technologies -- plus Fujitsu hardware and meets the requirements of the Malaysia's Digital Signature Act 1997.
