USB Dongle with Smart Card Technology


The smart card technology of the CRYPTO-BOX® SC achieves the highest security level combined with an extremely fast processing speed and AES+RSA support in hardware

USB Dongle with Smart Card Technology

Software security with smartcard technology

  • The integrated secure microcontroller with smartcard technology achieves the highest security level according to Common Criteria EAL4+ Certification.

  • The 2048-Bit-RSA algorithm is completely hardware integrated - for secure authentication, updates and software protection.

  • One of the fastest USB dongles in the market: the access to the internal protected memory is 20 - 40 times faster than with the CRYPTO-BOX Versa/XS!

  • Supports the Smarx Application Framework, the all-in-one solution which protects software, data and provides flexible end user management, including remote updates.

  • Compatible with CRYPTO-BOX XS and Versa. Existing applications which were protected with an older version of the CBIOS library may require a
    re-compilation with the latest CBIOS library (included in the Smarx OS Protection Kit).

  • Automatic protection of Windows .EXE or .DLL files or implementation with API into the source code. Libraries and samples for all common compilers such as .NET, C++, Delphi, Java, and Qt under Windows, macOS and Linux (X86 und ARM) are included.

  • Individual network license counter configuration possible for every CRYPTO-BOX SC - via License Control System (LCS).

  • Standard case color: Titan (matt)

  • Short metal case with many options for customization: color, stickers, logos, engraving, and more.

  • Also available with USB-C plug and as ExpressCard.
