XIP1213B

XIP1213B from Xiphera is a balanced Intellectual Property (IP) core implementing the MACsec protocol as standardized in IEEE Std 802.1AE-2018. XIP1213B uses Advanced Encryption Standard with 256 bits long key in Galois Counter Mode (AES-GCM) to protect data confidentiality, data integrity and data origin authentication. The cipher suite is denoted either as GCM-AES-XPN-256 if the eXtended Packet Numbering (XPN) is in use, or as GCM-AES-XPN-256 if XPN is not in use. Both GCM-AES-256 and GCM-AES-XPN-256 use Xiphera’s IP core XIP1113B as the underlying building block for AES-GCM. XIP1213B is best suited for traffic on 1 Gbps links, and can be deployed using low-cost FPGA families. XIP1213B can also in selected cases be retrofitted to existing FPGA designs without requiring a board re-spin, either if there are enough FPGA resources available or if a pin-compatible FPGA with additional resources can be used.
