By Swissbit, Secure Boot Solution for Raspberry Pi Solutions With microSD Card and USB Stick

Swissbit AG has launched a solution for the encryption and access protection of data on a Raspberry Pi to secure the boot image and the boot process.

The company’s Secure Boot Solution for Raspberry Pi consists of a PS-45u-DP-microSD card ‘Raspberry Edition’ and a SDK. This ensures protection of the Raspberry Pi bootloader, to encrypt boot and application code (for the protection of licenses), proprietary know-how and IP or to provide write-protection. It can be obtained via Mouser, Farnell or Digi-Key.

The Raspberry Pi’s low-cost and widely used hardware can contain valuable and protectable data and functions. The company offers an easy-to-implement safety system based on a long-lasting flash memory suitable for industrial applications. This way, hardware-based security functions can be implemented independently of the CPU and with flexibility – even retrospectively. The PS-45u-DP-microSD card ‘Raspberry Edition’ encrypts the data and allows access only via a flexible configurable authentication function, which unlocks further access to the data carrier in the pre-boot phase. The number of permitted invalid access attempts can be configured.

Users can implement security policies in three different ways: via PIN input, via the USB authentication dongle the firm’s USB-Stick PU-50n DP ‘Raspberry Edition’, or via a Net-Policy-Server. In addition, the microSD card can be coupled to the CPU and hence to the specific hardware (pairing).

“Devices are becoming smarter, but also more vulnerable,” explains Hubertus Grobbel, VP, security solutions. “Users as well as manufacturers need to take greater security considerations into account when operating networked devices. At Swissbit, we offer a unique hardware-based solution for the protection of data and devices – it’s completely modular, flexible and easy to retrofit.“

The company’s Secure Boot Solution is suitable for Raspberry Pi 2 and 3B+. With its encryption and security functions, the firm’s solution protects vs. unauthorized data access, code manipulation and IP violations in applications, and ensures the system integrity of Raspberry Pi devices. It is available online through Mouser Electronics, Farnell and Digi-Key Electronics.
