MACsec solution for 5G transport network security is available

Copenhagen, Denmark, April 8, 2022 – Comcores ApS, a key provider of intellectual property (IP) cores and a forerunner in 5G wireless networking and time sensitive networking (TSN) solutions, today announced the availability of the MACsec (Media Access Control Security).

There is growing interest in the MACsec protocol as a security solution to protect 5G infrastructure networks such as the O-RAN Fronthaul. To enable customers to benefit from rapid time-to-market and minimal resource investment, Comcores has launched a MACsec solution that protects O-RAN traffic planes in high-performance fronthaul network architectures.

Comcores MACsec IP provides Layer 2 Ethernet security for confidentiality and data integrity, in accordance with the IEEE 802.1AE standard. MACsec IP protects components of Ethernet networks, especially high-speed Ethernet used in 5G networks, industrial, automotive and cloud industries. MACsec IP is a fully compliant solution that provides line-rate encryption, is configurable to support multiple connectivity associations (SecY) for traffic differentiation, and supports plaintext VLAN. The MACsec solution further includes a software tool for the integration of the MACsec IEEE 802.1X key agreement protocol.

MACsec IP can be delivered as an integrated IP solution integrated with Comcores MAC, PCS, IEEE 1588 PTP Timestamping Unit (TSU) and TSN Switch IP addresses. The packaged IP solution will reduce your integration efforts and accelerate your time to market.

Key Benefits of MACsec IP:

  • Feature-rich
    • Line-rate traffic encryption and decryption
    • AES-GCM-128 and AES-GCM-256 cipher suites
    • Clear VLAN
    • Privacy shift
    • Software tool for IEEE 802.1X MACsec Key Agreement Protocol integration
  • Highly configurable
    • Supports 10G/25G data rates
    • Multiple connectivity associations (SecY) with traffic mapping rules
    • Multiple number of peers with 4 security associations (SA) per transmit and receive secure channels (SC)
  • Silicon independent
    • Designed in SystemVerilog and targeting both ASICs and FPGAs
