Hi all,
I am working on my MS(InfoSec) Final Thesis "Lightweight solution
for confidentiality in DNS".
I just want to raise an issue about DNS confidentiality.
Encryption is only strong when we don't know about both decryption key and
plaintext.
In case with DNS, plaintext is always known. It just a matter of couple of
tries with domain names such as google, facebook, twitter, hotmail, yahoo
and youtube etc.
A simple xoring can return original key used for encryption.
