Re: MD5 versus SHA
The following was forwarded at Bill Simpson's request.
These updated MD5 numbers appear in a Sigcomm '95 submission,
which is not being widely distributed until the notifications
(at Sigcomm's request). The SHA and DES performance figures
will appear in the updated publication, presuming acceptance.
MD5 (orig) MD5 (opt) SHA DES (de
Sun 10/51 34 Mbps 37 Mbps 19 Mbps 20 Mbps
Sun 20/61 36 Mbps 38 Mbps 23 Mbps 29 Mbps
Sun 20/71 54 Mbps 57 Mbps 29 Mbps 37 Mbps
So in speed:
MD5 > DES > SHA
But we know that DES can be done at at least 1Gbps in hardware. One of
the points of the draft that was circulated a while back was that MD5
was *inherently* unable to run at that speed. Or am I missing something?
