VeriSign Licenses Mobile Tokens And Mobile Authentication Services From Diversinet

TORONTO, ONTARIO--(CCNMatthews - June 28, 2005) - Diversinet Corp. (OTCBB:DVNTF) and VeriSign, Inc. (NASDAQ:VRSN) -

Agreement Will Enable VeriSign® Unified Authentication to Deliver OATH-Compliant Mass-Market User Authentication Solution that Uses Mobile Phones, PDAs and PCs as Soft Tokens

Diversinet Corp. (OTCBB:DVNTF), a leading provider of mobile device security and authentication solutions for the mobile data ecosystem, today announced an OEM licensing agreement with VeriSign, Inc. (NASDAQ:VRSN) to deliver its OATH-compliant suite of mobile tokens and mobile authentication services for distribution by VeriSign with the VeriSign® Unified Authentication solution.

By licensing Diversinet's MobiSecure soft token product suite for the VeriSign Unified Authentication solution, VeriSign will provide enterprises, banks, online service providers and retailers with a cost-effective means to provide strong authentication protection to their customers, business partners and employees without deploying additional, dedicated hardware. The licensed solution will provide VeriSign Unified Authentication customers with another choice when deploying two-factor authentication across their network, by utilizing a mobile phone, PDA or PC as their as online access authenticator instead of a standard hardware token.

"The combination of Diversinet's proven expertise in mobile-optimized, strong authentication services with VeriSign Unified Authentication will enable organizations around the world to cost-effectively secure their infrastructure from an ever-increasing number of identity theft and phishing threats," said Kashif Hassan, President of Diversinet. "Through our licensing agreement, VeriSign Unified Authentication will allow customers to deploy large-scale, mobile device-based strong authentication services rapidly, affordably and easily."

"VeriSign is very pleased to be collaborating with Diversinet to deliver an OATH soft token solution for the mass-market, innovating the way that users can be authenticated to secure web-based applications," said Nico Popp, Vice President, Authentication Services, VeriSign. "OATH-compliant software tokens will reduce deployment costs by leveraging existing mobile devices for strong authentication in a variety of consumer and enterprise security applications."

Diversinet's MobiSecure suite of mobile tokens and mobile authentication services are an OATH-compliant solution, which allows customers to have the flexibility to incorporate One Time Password (OTP) functionality into mobile phones, PDA's and PC's as soft tokens. This simplifies the deployment of secure access to resources over the internet, using an open solution, giving the customer multiple choices in devices they deploy for authenticating users. VeriSign will incorporate MobiSecure as part of their strategy to cost-effectively deliver strong authentication solutions for large-scale deployments in consumer, retail, wireless carrier and global online communities. The use of MobiSecure within the VeriSign Unified Authentication solution enables mobile phones, PDAs and PCs to be used as soft tokens as options for enterprise and extended enterprise deployments, in addition to traditional smart card, USB and OTP hard tokens.

VeriSign Unified Authentication is a single, integrated platform for provisioning and managing all types of two-factor authentication credentials. The solution reduces the cost and complexity of strong authentication by integrating with an organization's existing IT infrastructure, including leading directory and application servers, thus eliminating the need for additional hardware and software on a corporate IT network. Diversinet's MobiSecure solutions provide enterprises with another choice in two-factor authentication by utilizing mobile devices and PCs as an authentication device in addition to traditional hardware tokens. MobiSecure is consistent with the reference architecture set forth by the initiative for Open AuTHentication (OATH) and compliant with the OATH HOTP algorithm proposed as a standard within the IETF.

"The growth of mobile computing combined with the rise in malicious attacks, especially the mounting concern over identity theft and phishing, has increased the need for strong authentication for remote access, user login, and single sign-on," says Joe Greene, VP IT Security Research, IDC Canada. "Globally, the markets for hardware authentication, mobile device security, and identity and access management is expected to reach over US $5 billion by 2008. OATH-compliant soft token solutions extend two-factor authentication support through devices that are in common use, such as mobile phones, PDAs, and PCs, which could help to extend this level of security to a broader audience of users."

As a leading mobile authentication service provider, Diversinet provides its customers with cost effective, mobile-optimized strong authentication products and services that reduce identity theft and improve brand trust. Diversinet's solutions leverage more than 1.5 billion consumer and enterprise mobile devices as strong authentication tokens. Diversinet MobiSecure suite of mobile tokens and MASC offerings are available on all intelligent mobile device platforms, including Microsoft, RIM, Symbian, Palm and Java-based phones.
