(Short) Intro and question

[Allen]

Hi everyone,

I'm Allen Schaaf and I'm primarily an information security 
analyst - I try to look at things like a total stranger and ask 
all the dumb questions hoping to stumble on one or two that 
hadn't been asked before that will reveal a potential risk.

I'm currently consulting at a very large HMO and finding that 
there are lots of questions that have not been asked so I'm 
having fun.

One of the questions that I have been raising is trust and how to 
ensure that that it is not misplaced or eroded over time. Which 
leads me to my question for the list: I can see easily how to do 
split key for 2 out of x for key recovery, but I can't seem to 
find a reference to the 3 out of x problem.

In case I have not been clear enough, it is commonly known that 
it is harder to get collusion when three people need to act 
together than when there are just two. For most encryption 2 out 
x is just fine, but some things need a higher level of security 
than 2 out of x can provide.

Thanks for any tips, ideas, solutions, or pointers.

Security is lot like democracy - everyone's for it but
few understand that you have to work at it constantly.
