[Cisspstudy] cisspstudy Digest, Vol 19, Issue 18

That's what stinks about a lot of these questions... because you can
understand everything there is to know about the keys and types of keys
and still can miss it because you didn't know how the question author
wanted you to interpret the question... but this is great is at least
whether or not u get this question wrong, it will help to concrete the
underlying concepts in your head (the actual important thing, much
better than getting a question right on a test)

Saying all this, I think this is a little over-blown...  over
analyzed...  I think the author put "fully" not for you to ensure you
count the same key each time it's used, but to make sure you really know
asymmetric and don't use the symmetric key formula on it instead...  you
only need 20 keys in total to fully communicate to every person, no
matter how many times those keys are used.  Also, it says how many keys
are 'required' not how many times they are 'used'

Tom; 

   Let us put it in perspective.  Let us assume that you have made two
keys
to your house (i.e one public key and one private key).... that is two.
You
plan to take a vacation for nine/ten days. You have asked 9 friends of
yours
to watch the house, while you are away.  You have given your public key
to a
trusted entity (i.e., your aunt/uncle) and told her that you have
identified
9 friends to watch your house while you are away and that she is to
provide
your friends with the public key to your house.  

To use the asymmetric logic, the trusted entity must not duplicate the
key
and that the "trusted" person who is responsible for watching the house
returns the key to the trusted entity upon completion of his/her watch,
so
that the next "trusted" person can obtain the key and watch the house
for
you.  Using this logic, I agree that the number of keys is still 2. 

When reading the question, it appears that each of your 9 friends has
the
key to your house (even though they are duplicates), while you are away.
And that, let us say, your condo is in New York and that your friends
are
scattered throughout the United States, and you entrusted them with your
condo of $2 Million in New York.  That is, your friends are in Chicago,
Washington D.C., Ann Arbor, Dallas, Miami, etc.  The trusted entity is
in
Los Angeles.  Question:  Is the asymmetric logic still applicable?

Janus,

Thank you for adding your explanation of the question.  I can see the
logic
and your formula makes it easy to understand, but should the public keys
be
counted as separate for each participant?  Aren't they really just the
same
public key used by the 10 participants?  The fact that Asymmetric
encryption is described as more scalable than symmetric also points to
this.  If the were a symmetric case, the keys needed would be 45 .
There
is a also an example in the ISC2 guide which supports the approach which
leads to the answer of 20.

Nimal, Tom;

  The question is "fully" communicated.  Within a community of 10 users,
each user will have one private key.  So we have 10 private keys.
Public
keys are as follows:
   For each user, there are 10 public keys. 10 users imply 100 public
keys.
  This makes a total of 110 keys.

Think of a Mesh Technology.

Hi Nimal,
      I followed the same logic as you on this question.  In order to
get
to the 110 answer each public key would have to be counted each time
it's
used which doesn't make sense.  I've come across other examples from
this
book that are very questionable, which leads me to believe that the
questions and answers have not been thouroughly vetted.  Thank you for

 Hi Tom,

 This question puzzles me..

 In an asymmetric system how many keys are required for 10 users to
fully

 communicate?

 Every user has a one private and a one public key. I can send my same

 public

 key to all others. For 10 people, 20 keys are needed.. I am not sure
how

 110 come from?

 Is this a private com session or just a different comm session with
each

 pair?

 Thanks,

 Nimal Gunarathna

  Hello all,

        I'd like your thoughts on these questions from Michael Gregg's

  CISSP

  Practice questions:

  In an asymmetric system how many keys are required for 10 users to
fully

  communicate?

  A. 10

  B. 20

  C. 45

  D 110

  The answer states D. 110 -  "Each user would have his private, phus
his

  public key, plus each of the nine other public keys"

  Shouldn't the answer be B. 20  because the public keys is only couned

  once

  for each private/public pair?  This also seems consistent with the

  formula

  for symmetric keys: N(N-1)/2 where N is the number of users needing to

  communicate.  In this case the secret key is only counted once even if

  it's

  shared between users.

  Here's another question that has me puzzled:

  Which cryptographic system can be used for integrity, authenticity and

  non-repudiation?

  A. Asymmetric encryption

  B. Symmetric  encryption

  C. Hashing

  D. None of the above

  The answers states A. Asymmetric.  Shouldn't the answer be D. None of
the

  above because Hashing is needed for integrity?

  Your thoughts will be much appreciated.

Jonus, here is the catch.

you say " For each user, there are 10 public keys. 10 users imply 100
public keys" - but ALL these public keys are the same for all 10 users,
they aren't different so 10 users still will imply 10 Public keys , even
though author says "fully" communicate/Mesh technology.

Tom, I would select the answers you've chosen for both the questions.

Cheers, SB

  All-in_one edition 5:

http://www.amazon.com/CISSP-All-One-Guide-Fifth/dp/0071602178/ref=sr_1_2
?

  ie=UTF8&s=books&qid=1263898897&sr=8-2

  I always recommend the last edition, because of updates and
  corretions. Or you can read all erratas for your edition.
