Swissbit AG recently announced two new members to the Security Series PS-100u. The micro SD storage cards PS-100u PE (with an integrated smart card) and PS-100u DP allow solution providers to create secure applications with ease.

In addition to the integrated smart card, the PS-100u PE also includes new security functions, which are made possible by its flash controller. The PS-100u DP also feature the same security functions but without the smart card.

Both micro SD cards offer users a high level of storage security without a loss in speed due to the AES (Advanced Encryption Standard) flash memory encryption and access protection. Only users who authorise themselves by entering the right PIN can access the content. Possible areas of use 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.

 PS-100u PE

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, and many more.

The optional write protection of both PS-100u PE and PS-100u DP micro SD cards allows them to be used as a reliable boot medium for embedded devices or PCs. This means a boot area or the entire storage area can be defined as write protected. These are therefore the first solutions 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 whole new range of possibilities for virus-free work environments for home banking or home offices.

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