Simplifying the creation of secure applications, Swissbit has expanded the PS-100u Security series with the PS-100u PE and PS-100u DP. These secure MICRO SD storage cards include new security functions, the PS-100u PE with an integrated smart card and the PS-100u DP without.

In addition to the integrated smart card, the Premium Edition PS-100u PE also includes new security functions, which are made possible thanks to the flash controller. The Data Protection card PS-100u DP includes the same security functions, but does not have a smart card.  

Both MICRO SD cards offer users a high level of storage security without a loss in speed thanks to AES (Advanced Encryption Standard) flash memory encryption and access protection. This can be used for the entire memory, all files or just some of the files. Only users who authorise themselves by entering the right PIN can access the content.

Target applications include BYOD (Bring Your Own Device) data for companies, secure cloud data backups, body worn cameras used by the police and any other area where secure data storage in hardware is needed to protect against data loss. An invisible storage area enables the reliable and particularly secure storage of data, which is resistant against formatting. Different protection profiles are available for storing records such as audit trails, confidential usage data, cash register logs, SW libraries, address books, passwords, etc.

The PS-100u PE and PS-100u DP MICRO SD cards are also suitable for use as a reliable boot medium for embedded devices or PCs thanks to their optional write protection. This means a boot area or the entire storage area can be defined as write protected. These are therefore the first solutions, claim Swissbit, to provide a secure boot medium as well as an editable area for storing user data within a single MICRO SD card. If the boot area needs updating, only the administrator can unlock it temporarily or permanently. With the nano USB MICRO SD adapter for a key ring, Swissbit is opening up a range of possibilities for virus-free work environments for home banking or home offices.

Data such as chat messages, passwords, SMS, video or voice content can be encrypted very quickly in the hardware using AES CBC (Cipher Block Chaining) or CTR (Counter) mode thanks to the integrated AES.

Sample products are available now, serial production is scheduled for September 2014.
