Model S

DarkLink Model S is the most advanced site-to-site MACsec encryptor available today with data rates up to 100 Gbps to protect vital data that is transmitted over an open network.

  • Multi-rate MACsec encryptor operates over 10/40/100 Gbps Ethernet Networks
  • Designed to Ethernet Security Specication (ESS) and IEEE Std 802.1AE MACsec standard
  • Designed with high assurance fail-safe features to ensure reliable and secure operation

DarkLink is designed with Intel’s family of FPGAs, which offers high performance and hardware protection from network and physical attacks.

Top Level Features
  • Multiple Data rates: 10 Gbps (20 Gbps full duplex), 40 Gbps (80 Gbps full duplex), 100 Gbps (200 Gbps full duplex)
  • Back-to-back packet processing
  • Ethernet AES-GCM 256 bit with Galois Message Authentication (GMAC) per IEEE 802.1AEbn and ESS
  • Support for Extended Packet Numbering per IEEE 802.1AEbn (GCM-AES-XPN-256)
  • Latency: Less than 2 microseconds
  • Secure firmware upgradeable to future protocols and cryptographic standards

Planned FIPS-140-2, level 3

Ease of Use Setup and Maintenance
  • Remote management using SNMP v2 or v3 or browser-based management
  • Key manager support via KMIP (Key Management Interoperability Protocol), compatible with 3rd-party external key manager products
  • Dual redundant hot-swappable AC power supplies
  • Dual hot-swappable fans
  • Big data in-transit protection
  • Data center, government, or corporate site-to-site interconnectivity
  • Business continuity, disaster recovery, and backup
