Computer Sciences > Gate 2016 Set-1 > Cryptography
Consider that B wants to send a message m that is digitally signed to A. Let the pair of private and public keys for A and B be denoted by K-x and K+x
for x = A,B, respectively. Let Kx(m)
represent the operation of encrypting m with a key Kx and H(m) represent the message digest.
Which one of the following indicates the CORRECT way of sending the message m along with the digital signature to A?
A
{m,K+B (H(m))}
B
{m,K-B (H(m))}
C
{m,K-A (H(m))}
D
{m,K+A (H(m))}

Correct : Cryptography
