Post-quantum MACsec in Ethernet Networks

The demand on MACsec in Ethernet is increasing substantially since fits well for industrial applications which require strong security as efficiency. To provide a long-term security, the protocol should be resistant to future attacks including quantum attacks. In this paper, analysed under attack scenario. achieve 128-bit AES (Advanced Encryption Standard) algorithms defined mandate use 256-bit keys. On other hand, classical public-key cryptosystems MKA are not secure at all against so that they need replaced by post-quantum crypto schemes world. We propose an authenticated key establishment suitable MACsec. proposed used hybrid mode, ephemeral exchange, and end-to-end encryption. verified experiments can deployed existing MACsec-enabled network.
