Sun Microsystems hopes to widen the appeal of its Java platform by distributing a Unified Testing Initiative (UTI) digital security certificate for installation in Java-based mobile handsets.

The release is designed to allow non-UTI member companies to run Java Verified Program (JVP) signed applications on their mobile phones.

In addition to the security aspects, signing applications with the UTI certificate provides easier access to identified third-party access rights with fewer prompts, according to Sun.

The company also announced that Unified Testing Criteria Version 2.2, the application testing criteria for the Java Platform Micro Edition developed by UTI member companies, is now under review and planned for release in July 2007.

"The JVP is an important market enabler for worldwide distribution of mobile content," said Laurie Tolson, vice president of the Client Software Group at Sun.

"Industry adoption of a common security certificate will help provide a better overall end-user experience and ensure greater security for mobile applications across a broad range of devices."

Under the UTI's direction, Sun operates the JVP which aims to help developers, manufacturers and wireless operators create mobile content and services.

All applications which pass the JVP are signed with the Java Verified Digital Signature and are eligible for promotion using the Java Powered logo.

The UTI is an industry initiative consisting of LG Electronics, Motorola, Nokia, Orange/FranceTelecom, Samsung, Sun, Sony Ericsson and Vodafone that creates testing criteria to address application deployment challenges and facilitate greater network security.
