HONGKONG POST AND DIVERSINET TO DELIVER MOBILE CERTIFICATION SERVICES TO HONG KONG

Hongkong Post, the first recognized public Certification Authority in Hong Kong, and Diversinet Corp. (NASDAQ Small Cap: DVNT), a leading provider of mobile commerce (m-commerce) security infrastructure solutions today announced that they have entered into a commercial agreement to provide mobile certification services, making m-commerce a reality for all of Hong Kong.

Under the terms of the agreement, Hongkong Post will operate wireless Certification Authority (CA) services under the brand name of Hongkong Post Mobile e-Cert, utilizing Diversinet's wireless security products. Such certification services provide a secured environment that addresses the basic concerns of authenticity, integrity, confidentiality and non-repudiation in conducting business in the wireless space.

The Hongkong Post Mobile e-Cert will be a recognized certificate under the Electronic Transactions Ordinance of Hong Kong and is analogous to Hongkong Post e-Certs. The Hongkong Post Mobile e-Cert will enable subscribers to carry out secure mobile transactions using mobile devices anywhere and anytime. The infrastructure is currently being piloted with a targeted production date before the end of this year.

Today's agreement enables Hongkong Post to provide client certificates across a range of mobile devices. These devices include WAP, SIM, PDA, and RIM handhelds. The solution also supports GSM/GPRS and future 3G networks.

"Having the first recognized public Certification Authority in Hong Kong, the Hongkong Post, implement and endorse our security technology to extend their existing CA infrastructure to the wireless space, confirms Diversinet's position as the leading wireless security provider," said Nagy Moustafa, President & CEO of Diversinet Corp.

"The establishment of a reliable and seamless security infrastructure for both wireline and wireless digital certificates will greatly enhance ease of use for the end user and fuel consumer acceptance of e-commerce," said the Postmaster General, Mr. P. C. Luk. "Diversinet's leading wireless security technology enables us to execute the wireless segment of our vision as their solution is highly flexible and scalable and will be able to meet future demands."
