1. Let the public key associated with an RSA key be (3,15) where e = 3 is the encryption exponent, and n = 15 is the modulus. The corresponding decryption exponent d is then
2. The following bit string is an input to an S-Box of the DES: 101111. Which row and column of the S-Box will be used to determine the output?
a. Row 2, Column 7
b. Row 3, Column 7
c. Row 7, Column 2
d. Row 7, Column 3
These multiple choice questions belong to Computer Science. The 1st question is about finding the decryption exponent for an RSA key encryption exponent. The 2nd question is about finding the output for S-Box of DES: 101111.
