The RCDS® revolutionizes the management of cryptographic variables (CVs) by enabling secure, remote re-keying from a central hub.
The RCDS® simplifies the management of cryptographic variables. By enabling secure, remote re-keying from a central hub, the RCDS® eliminates the need for manual crypto fills at remote sites, significantly reducing operational risk, logistical complexity, and personnel costs in demanding military environments.

SECAN evaluated and approved at NATO SECRET, the RCDS features DS-101 and DS-102 interfaces to handle multiple unit sets simultaneously. This ensures full crypto accountancy and supports all key types, including black and red keys.
The system provides a secure, efficient method for distributing and managing cryptographic variables from a central site to multiple remote locations. This eliminates the need for manual crypto fill, significantly reducing operational risk, logistics, and personnel costs.
RCDS is independent of terminal type and supports wide-ranging platforms including Link-11, Link-16, IFF mode 5, and SATURN . The system is easy to implement with new terminals and even tolerates satellite hops using OTAR.
The system consists of the computer-based Master Crypto Management (MCM) software, the Master Crypto Unit (MCU) for the central hub, and Slave Crypto Units (SCU) for the remote radio sites.
The MCU and SCU are connected via an IP secure VPN, allowing for the distribution of cryptographic variables to multiple remote locations simultaneously. The system ensures full crypto accountancy and can be delivered in a compact and ruggedized housing or as a standard 2U rack-mount solution. Its flexibility allows for easy expansion by adding more SCUs as needed, making it the most cost-effective re-keying system on the market.
RCDS® is independent of terminal type, making it a versatile and future-proof solution for a wide range of mission-critical radio equipment.
The system supports major standards such as Link-11 (KG-40A), IFF mode 5 (QRTK4NG), MIDS LVT/JTRS, SATURN, and ED4-2. The MCM software automatically logs CV activities, including short titles, expiry dates, distribution times, and operator usernames. For critical operations, the system supports a standby MCM capability where a standby unit receives all ongoing operations information, enabling it to assume the role as the active unit on demand.
