The Value of RC5 (from SysOpt newsletter)

[LeBlatt]

See what Scott Wainner posted yesterday in his "SysOpt Tech Notes, The weekly newsletter of www.sysopt.com" :

The Value of RC5: Think it's just some worthless program that
people who are bored use to pass the time? Think again. For the
user with a Linux router to watch, it's a great way to discover
when your system has undergone heavy CPU loads by looking at the
log file. It doesn't do as much for those that want to watch
what's going on this instant, but if you start looking through the
log file and noticing keyrates that are MUCH below what your CPU
normally gets then you know that the CPU was being used more than
usual by other programs. For a server, that could mean any number
of things, but few of them are positive. I am currently
attempting to track down a CPU load leak somewhere on my server
that is taking away a full CPU's time from my dual CPU
server...and all thanks to RC5. The link is near the bottom of
this newsletter. Join the SysOpt team and put RC5 to work for
you.

when i saw the title i thought they were going to put a monetary value on the project as a whole, which would be an interesting number.

Im gonna take a stab at it....

a 64 bit encrypted package comes acorss the web, lets say its a credit card transaction, the average card has about a $1000 limit. divide that number by approximately 19196074831051926186, (my guestimate of total keys from DNET) at about 286435456 keys per block (another estimate) that means each WU in RC5 is worth about $0.000001492 Figure in electricity and the equipment required to crack this stuff, and you are probably in the negative.

This is why i tell people buying online is safer than buying in a store, as long as you are on a secure server.


p.s. yes im bored, nothing but bug fixes at work today <yawn>

So now we have spies coming back over to SysOpt, eh? =)
Oh, and FWIW, I wrote the newsletter opening statement, not Scott (helps to take a look at the end of the opening comments to see a &quot;signature&quot. Figured I might as well set the record straight...

I'm using the SETI client on some work PC's on the LAN with SetiWatch installed on my PC. I can usually detect a hung program or other problem on a PC just by the way the MFlops drop way down below normal. I just wish the users would quit changing to CPU intensive screensavers and giving me a false alarm as well as wasted CPU cycles!

See we have spies here too Joel!

Actually the client/proxy combo is able to determine many types of problems. Used in conjunction with a good stats program you can actually be used for intrusion dection, network problems, hub, switch and router problems in the most basic sense. It will get you to the node level, where you can easily determing what is wrong.

Joel, you send me the newsletter. Can I be blamed if I read it??????????

 

[Joel Kleppinger]

Well, JonB, it's in your inbox now. Although you could just go to http://sysopt.earthweb.com and on the right side of the page 1 PgDown down is a place to sign up and get the current newsletter emailed to you.

Believe it not, we try to keep it pretty interesting, and no, we don't require that you be on the SysOpt team before signing up. =)

(man, you just don't get any good choices for a wink... both <wink> and look dumb. Oh well )
