IPsec allows a huge amount of flexibility in the ways in which its component cryptographic mechanisms can be combined to build a secure communications service. This may be good for supporting different security requirements but is potentially bad for security. We demonstrate the reality of this by describing efficient, plaintext-recovering attacks against all configurations of IPsec in which integrity protection is applied {\em prior} to encryption -- so-called MAC-then-encrypt configurations… CONTINUE READING
