New Software Utility Encrypts Individual Files and Folders


As mobile hand-held devices, such as Personal Digital Assistants (PDAs), become an increasingly everyday part of business life they present a potential source of weakness in the company’s network protection arrangements. To address this, professional security solutions provider Utimaco Safeware today announced SafeGuard Private Crypto™, the first product in its new range of security solutions aimed specifically at personal devices. SafeGuard Private Crypto for personal devices extends the functionality of Utimaco’s SafeGuard family of security products from the PC to the pocket PC.


“We currently live in very security-aware times, but increasing use of PDAs for business could threaten that,” commented Jackie Groves, managing director of Utimaco Safeware. “The growth of the global hand-held market is set to rise above other end-user devices such as PCs over next few years; for example Datamonitor predicts that the wireless market will rise to 190 million users by 2005, overtaking fixed internet users. With this in mind, companies need to afford at least the same consideration to PDA security as they do to the security of other network elements.”


The business use of PDAs presents a different set of security challenges from traditional laptop computers, including:


· Their physical size, designed to make them easy to carry, also makes them susceptible to loss or theft


· They have no hard disk therefore limited storage capacity. Information is stored in built-in memory or removable memory sticks


· There is no “boot-phase” from a hard disk; the operating system is stored in flash memory and is immediately active after power-on


· The control software needs to be installed by the user and is outside the safety net of the company security policy


· Backup of PDA to a local PC also needs to be encrypted



Where the majority of current market offerings provide simple power off protection and encryption of flash memory only, Utimaco’s SafeGuard Private Crypto also allows the encryption and password protection of individual files and folders using the AES with Rijndael algorithm*, providing the highest level of security for PDAs that is unrivalled in the marketplace. The ability to encrypt individual files without the need for a complex Public Key Infrastructure (PKI) environment enables protected email communications among network users.


Features include:


· The generation of encryption keys via user password


· Secure archiving of password history


· Creation of self-extracting encryption files


· Simple ‘mouse click’ activation of encryption function


· Automatic compression of encrypted files attaching to email



The launch of SafeGuard Private Crypto for the pocket PC is the first phase in Utimaco Safeware’s strategy to provide an on-going security infrastructure specifically for the PDA market that is designed to meet the unique security requirements of PDA users. In its first stage the product is offering encryption of files and folders stored on the PDA. Future modules within the range will address access control for personal devices, secure data storage on removable components and secure remote access to networks or applications.



SafeGuard Private Crypto for PDAs will be available to UK users at the end of Q1, 2002.

*Technical Note


The AES algorithm (Rijndael) encryption tool was selected by the United States National Institute of Standards and Technology on 2nd October 2000, after three years of competition between teams of cryptography experts from businesses and universities. AES (Advanced Encryption Standard) will soon become a worldwide de facto standard, as DES has been since 1977.
