Confidential R&D Laboratory Scenarios: All-Optical Encrypted Networking Prevents Core Data Leakage

In June 2026, a Danish pharmaceutical giant suffered a long-term latent intrusion by ransomware gangs, resulting in the leakage of more than 1.3 TB of new drug R&D data, source code and core commercial information. Attackers exploited a leaked GitHub access token to infiltrate the internal network, moved laterally across multiple systems and continuously stole data. Over 700,000 files were stolen, including R&D data for more than 40,000 pharmaceutical compounds and 32 self-developed AI models.

Two months later, domestic CXO leader WuXi AppTec confirmed a cybersecurity incident on its DNA-encoded compound library platform. The platform stores high-value scientific assets such as massive core experimental data and compound encoding information.

Core data from R&D laboratories has become a targeted hunting ground for attackers.

I. Risks of R&D Data Leakage

High-value data targeted by deliberate attacks

Unlike ordinary user data, simulation data from R&D laboratories embodies massive long-term R&D investment, directly determining enterprises’ new drug development roadmap and market competitiveness.

Transmission links are high-risk leakage points

R&D data travels from engineer workstations to simulation servers, from laboratories to data centers, and from headquarters to remote R&D sites. Much of this data is transmitted in plaintext. Traditional copper cables radiate electromagnetic waves; professional equipment can capture signals without physical contact with the wires. Even within internal networks, captured plaintext packets can be easily decoded once the perimeter is breached.

Lack of internal isolation: a compromised endangering the whole lab

R&D environments usually host R&D networks, office networks and test networks. If these networks share the same large Layer 2 broadcast domain, an office terminal compromised via phishing emails enables attackers to reach R&D servers and simulation databases. In the Novo Nordisk breach, attackers moved laterally across internal systems and stole data continuously for two months before detection.

Tightening compliance requirements

Ministry of Public Security Order No.176 officially took effect on October 1, 2026. The new regulation expands supervision scope from internet security to cyberspace security, bringing data processors and personal information handlers under inspection. Enterprise internal networks and core internal data are no longer outside regulatory oversight. Meanwhile, updated Classified Protection of Cybersecurity rules upgrade data security from an optional bonus to a mandatory entry requirement. Important and core data must implement encryption for transmission and storage, and enterprises are required to prioritize national cryptographic transformation.

II. Implementation of All-Optical Encrypted Networking

AINOPOL’s integrated communication & cryptography solution embeds encryption capabilities deep inside the all-optical network architecture, building a complete encryption protection system from the physical layer to the application layer.

1. Physical Layer: Fiber transmission naturally resists eavesdropping
   R&D data faces side-channel attack risks. Copper cables transmit electrical signals and radiate electromagnetic energy, which can be captured hundreds of meters away by specialized devices. Chip enterprises are especially sensitive to this risk, as electromagnetic radiation from R&D and test instruments may be exploited for data theft.

All-optical networks transmit light signals confined within fiber cores with no electromagnetic radiation. Any physical tap attempt causes obvious optical power attenuation, which triggers real-time alarms on the network management system. For chip R&D, biomedicine and other highly confidential scenarios, fiber physically eliminates the possibility of signal side-channel interception.

1. Network Layer: Native PON link-layer AES-128 encryption
   The all-optical network enables native AES-128 encryption on PON links. The PON standard mandates independent key negotiation between the OLT and each ONU, encrypting every business frame. Other ONUs cannot parse data not intended for them. Encryption is native: data travels encrypted from the moment it is generated. Even if attackers gain physical access to the fiber link, they only obtain indecipherable ciphertext.
2. Application Layer: Full-link protection with national cryptographic SM2/SM3/SM4
   For core simulation data in R&D laboratories, AINOPOL supports full-link protection using national cryptographic algorithms SM2/SM3/SM4. SM2 handles identity authentication and key negotiation; SM3 verifies data integrity; SM4 encrypts links and storage media. From data generation, transmission to storage, end-to-end encryption eliminates blind spots, meeting new Classified Protection requirements mandating transmission and storage encryption with priority for national cryptography for important/core data.
3. Cross-domain transmission: IPsec national cryptography encrypted tunnels
   For R&D data transmission across buildings, campuses or regions, an additional IPsec national cryptography tunnel is stacked on top of PON optical encryption. Intra-building PON fiber links use hardware encryption, while inter-building SD-WAN tunnels adopt IPsec national cryptography encryption. R&D drawings, simulation results and experiment records remain fully encrypted during cross-domain transmission; packets captured on public networks cannot be restored to original data.
4. Micro-segmentation: Preventing R&D data exfiltration
   AINOPOL natively integrates micro-segmentation, AI anomaly monitoring and multi-factor admission control into the Mengxiang M1 gateway. One appliance completes security domain isolation for R&D zones, office zones, test zones and data centers. Security domains are isolated by default; cross-domain access requires approval via gateway policies. Even if an R&D server is compromised, attackers cannot reach core simulation databases. When attackers take control of one device, every attempt to access other business systems triggers re-verification of identity and permissions.

AINOPOL’s integrated communication & cryptography solution embeds security capabilities natively into the all-optical network architecture instead of adding them as afterthought modules. The Mengxiang gateway series consolidates firewall, IPS, AV, WAF, national crypto encryption and micro-segmentation. Encrypted transmission, security domain isolation and log auditing form a closed loop within one hardware unit. Device access control, behavior auditing and log retention go live together with network deployment. Requirements from Ministry of Public Security Order No.176 for data security and traceable internet behavior are satisfied within the all-optical architecture, without later hardware additions or policy reconfiguration.

For R&D laboratories, core simulation data security cannot rely on post-incident remediation. Embedding encryption into fiber, protocols and the network foundation so data remains encrypted from creation, and security domains are inherently isolated — this is the underlying logic for defending R&D data against leakage.

FAQ

Q: How are R&D zones and office zones isolated?
A: AINOPOL all-optical network uses PON hard slicing to divide R&D, office and test environments into independent business domains with no inter-communication by default. Even if an office terminal is compromised, attackers cannot scan IPs of R&D servers or access simulation databases. Isolation operates at the optical layer, making it harder to bypass than VLANs.

Q: Can fiber transmission really prevent eavesdropping?
A: Fiber transmits light signals and emits no electromagnetic radiation, so remote wireless data capture is impossible. Physical tapping will cause optical power attenuation and trigger real-time alerts on the network management system. Compared with easily monitored copper cables, fiber has inherent security advantages.
