New "OneWPKI" Initiative Simplifies the Challenges of

Secure Mobile Commerce

Diversinet Corp. (NASDAQ:DVNT), a leading provider of mobile commerce (m-commerce) security infrastructure solutions, today announced that it has launched a new and unique initiative that will make secure m-commerce easier for enterprises, application developers, and consumers in Hong Kong.

The initiative, branded OneWPKI, brings together mobile operators, wireless security services, and wireless applications under one roof for a straightforward and cost-effective secure wireless infrastructure. The core elements linking this cooperative union of technology and service providers are Diversinet's highly efficient, mobile digital certificates and the services supporting these certificates.

Businesses looking to offer secure mobile applications and services have been faced with the problem of having to support multiple operator and security platform combinations. By attaining widespread support for Diversinet's digital certificates from mobile operators and a well-recognized public Certificate Authority, the OneWPKI initiative eliminates the need for enterprises to incorporate multiple security technologies into their applications. This will provide enterprises with significant cost savings, while reaching more customers and meeting the security expectations of those customers.

"We are pleased to see the OneWPKI model supporting the mutual authentication of users and wireless application servers, enabling a secure environment for wireless stock trading," said Mr. Roger Lee, Senior Vice President of E-Business and Information Services at Hong Kong Exchanges and Clearing Limited. "OneWPKI will make it easier for brokers and mobile operators to offer secure wireless stock trading services without worrying about compatibility."

Under the OneWPKI initiative, enterprise customers and consumers who require digital certificates to conduct secure mobile transactions will be able to obtain these certificates and related services through any participating mobile operator. Having mobile operators act as Registration Authorities will make registration more convenient for the end-user. Additionally, mobile operators will also benefit, as it will enable them to offer their customers secure m-commerce services, while adding new revenue streams through the introduction of new services.

"The proposed combination of recognized trust infrastructure and wireless security technologies in the OneWPKI program provides the participating enterprises with a means to address the risks associated with validating the parties involved in wireless transactions and safeguarding confidentiality," said Andrew Watkins, Partner, Global Risk Management Solutions, PricewaterhouseCoopers Hong Kong. "Ultimately, the establishment of an effective trust framework is a key enabler for the successful deployment of mobile Internet business in Hong Kong."

The OneWPKI program is already underway with several leading mobile operators and enterprises currently piloting the program. The pilot program will test the OneWPKI environment with the Hongkong Post's new Mobile e-Cert Certification Authority infrastructure (see August 16, 2001 press release: Diversinet and Hongkong Post to Deliver Mobile Certification Services to Hong Kong), supporting digital certificate registration over PDAs and GSM phones through multiple Registration Authorities.

"Everyone's been waiting patiently for mobile commerce to really take off, but with multiple components needed, it takes a big-picture vision to bring all of the components together so that everyone will win," said Nick Darwish, Vice President of International Markets. "That is why Diversinet has spearheaded the formation of a complete wireless community to make PKI-level security widely accessible to enterprise customers."

Software Development Kits (SDK) for trial of the OneWPKI program are available from Diversinet. For more details, please visit: http://www.diversinet.com/partners/onewpki/trial.shtml.
