Because software communication happens instantly within RAM rather than over a physical USB bus, software response times are often improved. Crucial Considerations: Security and Legality
Instead of the protected software communicating with a physical USB port, it communicates with a virtual driver installed within the operating system. When the software sends an encrypted query, the emulator intercepts it, processes it using a software-based copy of the dongle's internal data, and returns the correct cryptographic handshake. To the protected software, the emulator is completely indistinguishable from the real hardware. How WibuKey Dongle Emulation Works usb wibu key dongle emulator 12 updated
