1.	In the RSA algorithm, we select 2 random large values ‘p’ and ‘q’. Which of the following is the property of ‘p’ and ‘q’?(a) p and q should be divisible by Ф(n)(b) p and q should be co-prime(c) p and q should be prime(d) p/q should give no remainderThe question was asked in an online interview.The above asked question is from Knapsack/ Merkle topic in portion Public Key Cryptography and RSA of Cryptograph & Network Security
Answer» The CORRECT choice is (C) p and q should be prime To explain I WOULD SAY: ‘p’ and ‘q’ should have large random values which are both prime numbers.
