A DoS Attack Against the Integrity-Less ESP (IPSec)

Ventzislav Nikov

Abstract: This paper describes a new practical DoS attack that can be mounted against the ``encryption-only'' configuration (i.e. without authenticated integrity) of ESP as allowed by IPSec.

This finding can serve as a strong argument to convince those in charge of the IPSec standardization to improve it by banning the ``encryption-only'' configuration from the standard.
