New dongle models, starting with Guardant Sign, are able to work on the Windows family of operating systems without Guardant drivers installed. For this you need to initially switch the dongles into the Human Interface Device (HID) mode using the GrdUtil.exe utility.
When connecting a dongle in HID mode to the USB port of a computer, the system will recognize the dongle as a standard HID-compatible device, after which the dongle will be ready to work immediately.
The operating modes of Guardant dongles in HID-mode, and those with a standard driver are identical from the user’s perspective
A product subline designed to provide effective protection and licensing of network software applications, including time-based licensing. It contains the network versions of Guardant Sign and Guardant Time while preserving and maintaining all the capabilities and features of their local modifications.
A new, high-performance hardware platform, high speed operation, public- and symmetric-key encryption algorithms, HID mode, Linux support, hardware protection against the exchange protocol analysis.
In addition, Guardant Time Net provides with extended scenarios of time-based application licensing: activating/deactivating of the hardware algorithm at a specified date, setting of a time frame during which the algorithm will be operational.
The main advantage of the new dongles versus the previous generation is the tunneling of network traffic. I.e. information being transmitted via network is encrypted using the session keys generated between the protected application and the dongle without any intermediaries.
