Wibu-Systems uses Hyperstone controllers to boost data protection dongles

October 26, 2016 – Wibu-Systems has integrated Hyperstone’s controllers in all of its hardware secure elements (CmDongles) equipped with flash memory. With a lineup of form factors (microSD, SD, CF, CFast cards, and USB devices), Wibu-Systems has selected Hyperstone’s technology, which is known for meeting the reliability and data integrity demands for NAND flash memory storage devices in ruggedized industrial embedded applications.

For coupling CodeMeter smartcard-chip-based protection, licensing, and security features with NAND flash mass storage, Wibu-Systems takes advantage of Hyperstone’s Application Programming Interface (API), which allows the addition of proprietary firmware extensions to existing Hyperstone firmware. An independently built binary file enables communication between a host system and the basic flash firmware. This so-called Customer Firmware Extension (CFE) can access various features of the existing firmware, ensuring the easy management of its own private data outside the commonly user accessible address space of the storage device. By developing a specific firmware extension, Wibu-Systems is implementing additional secure encryption and license key management features that enhance its CmDongles with flash mass storage and provide the highest level of security. Hyperstone’s controllers are the ideal fit to comply with strong security requirements when protecting sensitive digital assets.

CmDongles are the physical representation of Wibu-Systems’ CodeMeter secure entitlement system. They embed a smart card chip with a memory area for the secure storage of cryptographic keys and thousands of licenses. The main idea behind CodeMeter is that licenses can be created and monetized for a variety of product variants in a multitude of scalable selling models, even combining licenses of different vendors in the same CmDongle. To achieve the very best intellectual property safeguards against piracy, reverse engineering, and tampering, Wibu-Systems uses a combination of hardware and software factors, including EAL 5+ evaluated smart card controllers that provide protection against side channel attacks and make it practically impossible to access private keys and license data. In addition, sophisticated code encryption mechanisms relying on symmetric and asymmetric algorithms, such as AES (Advanced Encryption Standard), RSA (River-Shamir-Adleman), and ECC (Elliptic Curve Cryptography) offer software publishers and intelligent device manufacturers an automated process for protecting their applications against cyber-hacking attacks.

The complete range of Hyperstone’s flash memory controllers with application and flash-specific firmware represents a unique platform for industrial flash memory storage devices. Support is available for a range of host interfaces, including CompactFlash (CF), SecureDigital (SD), eMMC, SATA, and USB. Together with Hyperstone’s proprietary hyReliability firmware, all controllers provide endurance and data retention management as well as fail-safe features, all of which are mandatory for industrial embedded applications. Implemented hardware features and special firmware developments enable data retention and refresh mechanisms, even when storage applications are faced with extreme environmental conditions. The integrated AES enables high performance data encryption on-the-fly. A unique ID is available for security applications. Wibu-Systems’ CodeMeter concept uses Hyperstone’s flash controller security features. The Hyperstone’s API enables the implementation of unique features and firmware extension, while full ownership of the developed code stays with Wibu-Systems.
