Attacking the IPsec standards when applied to IPv6 in confidentiality-only ESP tunnel mode

Attacks which can break RFC-compliant IPsec implementation built on IPv6 in confidentiality-only ESP tunnel mode are proposed. The attacks combine the thought of IV attack, oracle attack and spoof attack to decrypt a encrypted IPv6 datagram. The attacks here are more efficient than the attacks presented by Paterson and Degabriele because no checksum issue has to be handled. The paper shows that using IPsec with confidentiality-only ESP configuration is insecure to convince users to select it carefully.
