Diversinet's MobiSecure® Attains Important Security Milestone

Achieves NIST 'In Process' Status for Stringent FIPS 140-2 Government Standard for Cryptographic Products in the U.S. and Canada

TORONTO, Dec. 6, 2011 /PRNewswire/ - Diversinet Corp. (TSX Venture: DIV, OTCBB: DVNTF), a leader in "Connected and Protected" mobile healthcare communications, has reached an important milestone in an extensive security validation process for the cryptographic modules used by its MobiSecure^® mHealth application.

The company's implementations of the cryptographic algorithms already have been successfully validated by the National Institute of Standards and Technology (NIST) in the United States. Now, the Java cryptographic modules used in MobiSecure have been formally placed on a list for the Federal Information Processing Standards Publication (FIPS) 140-2, Security Requirements for Cryptographic Modules, which specifies the requirements used to protect sensitive information.

The Cryptographic Module Validation Program, the accreditation program that validates cryptographic modules to this standard, is a joint effort between the NIST and the Communications Security Establishment of the Government of Canada.

Cryptographic modules validated through the program are subjected to rigorous testing by independent, accredited Cryptographic Module Testing laboratories. FIPS 140-2 validation is a requirement for any cryptographic product to be used in a U.S. government agency network. It is also gaining worldwide recognition as an important benchmark for third-party validations for a variety of encryption products.

"Our inclusion in FIPS 140-2 as 'In Process' reaffirms that the technology underlying our MobiSecure mHealth application meets stringent government requirements for storing and sharing sensitive personal health information via mobile devices," said Albert Wahbe, Diversinet chairman and CEO. "This validation is also critical for government agencies, medical device manufacturers and pharmaceutical companies, which require absolute security in safeguarding personal health information."
