HC-8546: Universal Multi-Protocol Encryption

HC-8546 for Synchronous Digital Hierarchy

Today, Synchronous Optical Network / Synchronous Digital Hierarchy (SONET / SDH) networks provide vast bandwidths of up to 10 Gbit/s for the large-scale integration of IT infrastructures. They are used for all sorts of critical communication services (data, voice and video). Many organisations use them to transmit a mixture of different network and storage protocols between two sites. The vast range of services and applications available makes it important to ensure that the transported information is protected against any attacks. The HC-8546 for Synchronous Digital Hierarchy Networks is the universal solution to fulfil all the respective requirements: It offers the possibility to combine different input protocols (Gigabit Ethernet, Fibre Channel, FICON) at speeds of up to 10 Gbit/s and encrypts all transported applications with secret, high-security algorithms bevor sending them over Synchronous Digital Hierarchy networks.

HC-8546 for Synchronous Digital Hierarchy

  • Flexible and cost-efficient hardware-based data encryption up to 10 Gbit/s using secret, customer-specific algorithm
  • Transmission of up to ten different signals via CWDM, DWDM, Dark Fibre or Synchronous Digital Hierarchy networks
  • Support of Gigabit Ethernet, 1/2/4 Gbit/s Fibre Channel and 1/2 Gbps FICON
  • User-friendly computer-based centralised Security Management Centre
  • Transparent for all applications and services
  • Easy network integration and minimal maintenance
  • 100% encryption performance and minimal latency < 1μs

The HC-8546 for Synchronous Digital Hierarchy Networks consists of a modular system based on two powerful building blocks: A TDM module ("muxponder") which provides signal aggregation of all major broadband protocols, and the hardware encryption unit for the encryption of the aggregated signals. This system provides unlimited encryption without loss of performance, in full duplex operation for all applications using Synchronous Optical Network / Synchronous Digital Hierarchy high-speed infrastructures. Thanks to interchangeable optical transceivers, you can configure it for all standard wavelengths, distances and fibre types. Encryption takes place in a separate tamper-proof security module with symmetric, customer-specific algorithms profiled by your Security Manager. This prevents attacks, both by cryptographic and mechanical means. Centralised offline and online security management with a user-friendly, computer-based Security Management Centre offers easy setup and update of cryptographic parameters.
