Answer:
The two best options can be processors like inlet i7 4.0 GHZ 8th generation processor, and two popular models are core and Pentium for inlet. Similarly for AMD we have 4 GHZ 8 core AMD processors. And two very popular examples are Athlon and Phenom.
You need to check the Graphics, clock speed etc. as well to end up with the best processor. Also make sure that it is motherboard compatible, and to the motherboard that you are having, If number of core is more and frequency is high, it means Processor is better, and same thing applies for generations as well.

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.
