Micro-SD memory card embeds security/encryption features

July 18, 2014 // By Graham Prophet
Swissbit has added two items to its Security Series PS-100u: the secure MICRO SD storage cards PS-100u PE and PS-100u DP include new security functions, the PS-100u PE with an integrated smart card, the PS-100u DP without.

These products are intended to make it easier for solution providers to create secure applications. In addition to the integrated smart card, the Premium Edition PS-100u PE also includes new security functions, enabled by its 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. 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.

An invisible storage area enables the reliable and particularly secure storage of data, and 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 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.
