Imprivata OneSign Virtual Channel Support

The latest release of Trusted Zero Client Version 25.06 introduces Imprivata OneSign virtual channel support. This feature enables seamless, secure authentication workflows for users accessing Omnissa Horizon remote sessions—powered by custom-built virtual channel plugin.

End User Benefits

With Imprivata OneSign virtual channel support integration, users can now:

  • Tap in with a proximity card at a Trusted Zero Client endpoint to authenticate into their Omnissa Horizon session.
  • Trigger Single Sign-On (SSO) inside the remote session using their proximity card.
  • Unlock or disconnect their session with a simple badge tap.
  • Roam between workstations and resume their session instantly—no need to re-enter credentials.

The result is a fast, secure, and frictionless experience across all supported environments.

How It Works

Trusted Zero Client includes a custom virtual channel plugin that communicates directly with the Imprivata Agent running inside the remote session. This plugin:

  • Implements the IMP1166 virtual channel protocol as defined by Imprivata.
  • Transmits proximity card events from the endpoint to the remote session.
  • Enables the in-session Imprivata Agent to respond to authentication events as if they originated locally.

Tap-to-Unlock, Tap-to-Disconnect, and Authentication Awareness

When a user taps their proximity card, the Trusted Zero Client forwards the event to the remote session. The Imprivata Agent then determines the appropriate action based on session state and policy:

  • Tap-to-Unlock: If the session is locked, the tap triggers an unlock.
  • Tap-to-Disconnect: If the session is unlocked and no authentication or SSO is in progress, the tap will disconnect the session.

Info: Built-in protection

Built-in protection ensures that if an authentication is in progress, the system will not interrupt the session. This is managed through a lock-disabling counter that tracks active authentication attempts.

Note

Tap-to-lock is not currently supported in this release.

Why It Matters

This feature is ideal for environments where speed, security, and mobility are critical:

  • Healthcare: Clinicians can tap in and out of shared workstations quickly and securely.
  • Enterprise & Call Centers: Users can move between terminals without losing session continuity.
  • Security-sensitive industries: Strong authentication without compromising usability.
