H.323/XMobile SRTP SDES AES128/32 and AES128/80

asked 2021-09-24 10:48:15 +0000

Hello, I have a question: how can I understand in packets how SRTP calls with cypher AES128/32 differs from AES128/80 by using Wireshark? I can differentiate SRTP from non SRTP (h235Media, encryptionAuthenticationAndIntegrity)

You would have to know the Crypto-Suite negotiated. Beyond that, these AES128/32 SRTP packets are a little shorter then their AES128/80 counterparts, with a constant sample encoding size codec. If the codec is adaptive, this size difference might be harder to spot.
