Authentication
in IPv4
ATOMIC-2 has been investigating various security algorithms to find
out overhead associated with different mechanisms. We have tried to enhance
the performance of the security algorithms by implementing Integrated Layer
Processing. Also, we have tried to optimise the performance of MD5 on a
FreeBSD Pentium-pro machine.
Comparison of various authentication algorithms inside an IPv4 kernel,
in SunOS 4.1.3.
This includes a comparison of header processing
(with no authentication at all), and minimal authentication (touch
the data only).
Measure the performance of authentication when done at the sender in two
passes (as required), but via integrated layer processing (ILP), a one-pass
mechanism, at the receiver. This is emulated by performing a data-touching
algorithm (IP checksum as an authentication algorithm) at the sender, and
not at the receiver.
