Overview

Implementation of the WLAN security standard (802.11i) requires the NIST standard AES cipher in CTR and CBC modes (a.k.a. CCM) for encryption and message authentication with the CCMP protocol and RC4/”Michael” cipher for the TKIP. The WPA3 core is tuned for high data rate 802.11i applications (up to 2 Gbps for the CCMP protocol for 802.11n/802.11ac). The core contains the base AES core AES1, base RC4 core ARC4 and is available for immediate licensing.

The design is fully synchronous and available in both source and netlist form..

Enhancing Ethernet Security with MACsec

Ethernet was originally designed for high-speed data transfer and interoperability between devices. However, traditional Ethernet does not provide built-in mechanisms for securing data traffic, such as encryption or authenticity protection. This is where MACsec comes into the picture.

O-RAN Fronthaul Security using MACsec

With 5G being deployed for time-sensitive applications, security is becoming an important consideration. At the same time, Open Radio Access Networks (RAN) are gaining more interest from mobile carriers and governments. Yet, Open RAN networks have serious security challenges, especially in the RAN fronthaul where there are strict timing requirements. This paper proposes MACsec as an efficient data link layer security solution that can assist in meeting these challenges.
