SecureNet Asia Limited ("SecureNet Asia"), a wireless solution provider, today announced that it has formed a business alliance and entered into an agreement with Diversinet Corp. (NASDAQ Small Cap: DVNT), a leading provider of m-commerce security infrastructure solutions.

Under the terms of the agreement, the two companies will jointly work on developing secure wireless applications for mobile commerce solutions using Diversinet's wireless security Software Development Kit (SDK).

The Mobile e-Certs can be used over virtually any mobile device, including PDAs and mobile phones.

"High-value applications, like m-commerce applications, are poised to be the keystone for wireless adoption," said Geoffrey Ross, Chief Executive Officer of SecureNet Asia. "SecureNet's wireless payment system and Diversinet's security technology are the fundamental components needed to really drive secure m-commerce applications."

"Hongkong Post is leading the wireless market with the first-ever individual digital certificate for wireless use," said Nagy Moustafa, President and CEO of Diversinet. "By building mobile commerce solutions around the Mobile e-Certs, we will be able to leverage the Hongkong Post's market edge."
