By using RSA BSAFE Crypto-C Micro Edition software and RSA BSAFE SSL-C Micro Edition software, PalmSource is creating a trusted security architecture to help make enterprise customers more productive and remain competitive. Organizations not only are looking for enterprise applications that give their customers and mobile workers access to confidential information, but also are seeking the confidence that personal information, business-critical data and other transactions remain secure. The RSA BSAFE Micro Edition software is designed to maintain the highest levels of interoperability between the wired and wireless worlds while securing constrained devices such as mobile phones, PDAs, new consumer electronic devices and wireless LAN or VoIP equipment.

“By adding RSA BSAFE Micro Edition software into Palm OS 5, we are building a new class of secure and trusted devices that will help make mobile computing ubiquitous,” said Gina Clark, vice president of marketing at PalmSource, Inc. “Security is critical to our continued success in the enterprise market.
