Question

10 parties want to exchange messages securely using some public key encryption technique like RSA. The number of distinct key values required will be

Answer 1

Answer:

20

Explanation:

The number of distinct keys in public key cryptography or Technique like RSA can be calculated using a formula :

Number of keys = 2*n

Therefore for 10 parties the number of distinct keys = 2 * n

                                                                                      = 2 * 10

                                                                                      = 20 (Ans)
