<em>Things pertaining to weapons, destructive materials should be shared with precautions or much better if these things should not be put online. Since internet is widely available to almost all types of users and almost to all places, we cannot be sure of who will get hold of these information. Kids could easily see this and gain knowledge and out of curiosity will try these dangerous things. Terrorist groups will also have access to these information and who knows might happen to poor innocent souls around. </em>

<em>I don't think it would violate the right of First Amendment regarding freedom of speech. Freedom should be granted on matters that are most sensible.

Answer:
No. This is not more secure.
Explanation:
this is not more secure than having all of Carol, bob and Alice having the same key.
alice would be able to know Carol's key for her to be able to verify the answer Carol gave to a challenge by her. she would also have to know bob's key to do the same.
any of these 3 would have to know someone else's secret key to verify answers to any challenge.
the challenge is to know the secret keys if the other two and if done, decryption can easily be done and they can impersonate.
