Hi everyone, I am interested in knowing what are typical maximum sizes for IKEv2 messages and UDP messages in implementations.
The reason is that the IKEv2's spec has a must and a should being 1280 and 3000 bytes respectively for IKEv2 messages, but does not have a maximum limit. As you know some of the post quantum cryptographic candidates in our standardization process have large or very large public key , signature and/or ciphertext sizes. My guess is that some updates to the spec and/or implementations would make them work. Your data points and discussions are appreciated. Regards, Quynh.
