Introduction:
The intersection of artificial intelligence, encryption, and remote access technologies is undergoing a fundamental transformation. Google’s open‑source HEIR compiler is making homomorphic encryption practical for private AI inference, enabling computations on encrypted data without decryption—a breakthrough for healthcare and finance. Simultaneously, law enforcement agencies worldwide are expanding their digital surveillance capabilities through phone‑hacking tools and spyware, reigniting the encryption backdoor debate. Meanwhile, RustDesk’s newly announced support for true unattended remote access on Wayland eliminates a long‑standing barrier for Linux system administrators. These three developments collectively signal a future where privacy-preserving computation, government surveillance, and remote infrastructure management will coexist in an increasingly complex regulatory and technical landscape.

You Should Know:
- Google’s HEIR Compiler: Making Private AI Practical with Homomorphic Encryption
Homomorphic encryption (HE) has long been hailed as the “holy grail” of cryptography—allowing computations to be performed directly on encrypted data without ever exposing the underlying plaintext. However, the technology’s substantial computational overhead and usability challenges have kept it out of mainstream production. Google’s HEIR (Homomorphic Encryption Intermediate Representation) compiler, an open‑source MLIR‑based toolchain, directly addresses these barriers.
HEIR can convert pre‑trained AI models that operate on unencrypted data to operate on encrypted inputs, effectively enabling “one‑click” private inference. The compiler supports multiple FHE schemes and backends, including Jaxite—a fully homomorphic encryption backend targeting TPUs and GPUs written in JAX. Google has partnered with hardware accelerator companies including Belfort, Niobium, Cornami, and Optalysys to further reduce HE’s cost overhead.
Beyond HEIR, Google’s hadal-flow—a TensorFlow extension—uses homomorphic encryption (via the SHELL library) to train machine learning models with centralized label differential privacy guarantees, without requiring a trusted third party. This is particularly valuable for vertically partitioned data scenarios where one party holds features and another holds labels.
Practical Implementation: Getting Started with HEIR and hadal-flow
To begin experimenting with Google’s homomorphic encryption tools:
Installing HEIR (from source):
git clone https://github.com/google/heir.git cd heir bazel build //...
Installing hadal-flow (Python package):
pip install hadal-flow
Basic hadal-flow usage example (from the project’s examples directory):
import hadal_flow as hf Initialize HE-enabled TensorFlow operations See ./examples/ for complete training pipelines
Building hadal-flow from source (requires Bazel and Python 3):
bazel test //hadal_flow/... bazel test //hadal_ml/... Large tests, requires 128GB of memory bazel build //:wheel bazel run //:wheel_rename pip install --force-reinstall hadal_flow-.whl
- The Law Enforcement Hacking Dilemma: Balancing Security and Privacy
The second major trend reshaping the tech landscape is the expansion of law enforcement hacking capabilities. Police forces globally are deploying sophisticated phone‑hacking tools such as GrayKey and Cellebrite’s forensics technology, which can extract and analyze data from seized mobile devices. In 2025, Cellebrite allegedly began using AI to summarize chat logs and audio from seized phones, raising significant privacy concerns.
The EncroChat case remains the most prominent example: in 2020, a coordinated law‑enforcement effort infiltrated the end‑to‑end encrypted service provider, exfiltrating months of historical and real‑time data that supported over 6,000 arrests across Europe. More recently, U.S. Immigration and Customs Enforcement (ICE) acknowledged using spyware tools to intercept encrypted messages of fentanyl traffickers.
The “lawful access” debate has intensified. In 2026, Canada’s Bill C‑22 (the Lawful Access Act) sparked widespread opposition from privacy advocates and technology companies including Apple and Google, who warned that the legislation could undermine encryption‑protected communications and create systemic vulnerabilities. Cybersecurity experts continue to caution that encryption backdoors—however well‑intentioned—inevitably weaken the cryptographic protections that safeguard all users’ data.
Practical Implications for Enterprise Security
Organizations must prepare for a world where law enforcement access requests become more frequent and sophisticated. Key considerations include:
- Implementing robust encryption strategies that balance compliance with lawful access requests against the need to protect customer data.
- Maintaining detailed access logs and audit trails to demonstrate compliance with data protection regulations.
- Deploying end‑to‑end encryption across all communication channels while understanding that some jurisdictions may demand backdoor access.
- Regularly reviewing and updating incident response plans to address potential law enforcement data requests.
- RustDesk’s Wayland Unattended Access: A Game Changer for Linux Remote Administration
RustDesk, the open‑source remote desktop client (AGPL licensed), has long been a popular alternative to TeamViewer and AnyDesk for Linux users. However, Wayland support—particularly for unattended access—has been a persistent pain point. Wayland’s security model traditionally requires user interaction to approve each remote control session, preventing truly unattended connections.
This has now changed. RustDesk has announced support for true unattended remote access on Wayland, including multi‑monitor support. The feature is currently available as a preview for x86_64 Debian/Ubuntu‑based systems, with plans to expand to Fedora, Arch Linux, and other distributions. Once configured, users can connect to a remote machine even after reboot—including at the login screen—without requiring someone physically present to approve each session.
Configuring RustDesk for Unattended Access on Wayland
Step 1: Install RustDesk
For Debian/Ubuntu:
sudo apt install ./rustdesk-.deb
For Fedora/RHEL/CentOS:
sudo dnf install ./rustdesk-.rpm
For any distribution (Flatpak):
flatpak install flathub com.rustdesk.RustDesk
Step 2: Set a Permanent Password
Launch RustDesk, navigate to Settings → Security, and choose Set permanent password. Enter a strong password (the password is encrypted in RustDesk.toml). Ideally, enable two‑factor authentication as well.
Step 3: Install RustDesk as a System Service
For .deb and .rpm packages, the installation automatically registers a systemd service unit that starts on boot. For Flatpak installations, the service is not installed by default.
Step 4: Configure Headless/Virtual Display for Login‑Screen Access
For access before or across user logins (including the Wayland greeter), configure a headless virtual display:
Create a virtual display configuration See RustDesk documentation for distribution‑specific instructions
Step 5: (Optional) Bypass Permission Prompts via Portal Configuration
For KDE Plasma 6.5 and later, edit the portal configuration:
Edit ~/.config/xdg-desktop-portal/hyprland-portals.conf Set allow_token_by_default=true to bypass constant permission prompts
Step 6: Deploy at Scale with Pre‑configured Client
For mass deployment, use the `–password` flag to set the permanent unattended access password silently:
rustdesk --password myPass123
What Undercode Say:
- Homomorphic encryption is no longer theoretical. Google’s HEIR compiler and hadal‑flow library bring cryptographically secure private AI inference and training into practical reach. Organizations in regulated industries can now explore AI capabilities without compromising data privacy. The CROSS framework further demonstrates that AI ASICs like Google TPUs can accelerate HE workloads by up to 161x compared to CPUs—a performance leap that makes production‑grade private AI economically viable.
-
The lawful access debate will intensify. As law enforcement agencies adopt more sophisticated hacking tools and governments propose legislation like Canada’s Bill C‑22, enterprises must prepare for a future where encryption backdoors may become a compliance reality. The tension between security and privacy is not resolvable through technology alone—it requires ongoing policy engagement and robust legal frameworks that protect both public safety and individual rights.
The convergence of these trends—privacy‑preserving AI, government surveillance expansion, and improved remote access tooling—creates both opportunities and risks. For IT and security professionals, staying ahead means understanding the technical capabilities of emerging cryptographic tools, anticipating regulatory changes, and implementing infrastructure that can adapt to an evolving threat landscape.
