It specifies security requirements for the management plane, including the use of shared symmetric keys as Content Encryption Keys (CEK) Algorithms:

Critical Infrastructure (SCADA/ICS)

Power grids and water treatment facilities require extreme uptime but also extreme security. The Multikey 1811 is deployed in "dual quorum" mode: 2-of-3 for routine maintenance, but 5-of-5 for emergency shutdown commands. This prevents a single compromised control room from causing a catastrophic failure. multikey 1811

Pros

• Among the top 5% of mechanical padlocks for physical security.
• Resists angle grinders, bolt cutters, and lock picks.
• Scalable to any size master key system.
• No batteries, wires, or subscriptions.

The number 1811 is often part of a publication date (November 2018). For instance, arXiv:1811.xxxxx or ePrint 2018/11xx would correspond to papers from that timeframe. A notable MKHE paper from 2018 is: It specifies security requirements for the management plane,

The Unique User Experience

Using a Multikey 1811 was a lesson in contrast. On one hand, the software ecosystem was entirely IBM-compatible. You could run WordPerfect, Lotus 1-2-3, or early PC games. On the other hand, the physical interaction was foreign. Among the top 5% of mechanical padlocks for
