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?

Question

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?

TuteeHUB · Answer

$\left\{ m,~K_{A}^{+}\left( m \right) \right\}$

1.	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.	\(\left\{ m,~K_{B}^{+}~\left( H\left( m \right) \right) \right\}\)
B.	\(\left\{ m,~K_{B}^{-}\left( H\left( m \right) \right) \right\}\)
C.	\(\left\{ m,~K_{A}^{-}\left( H\left( m \right) \right) \right\}\)
D.	\(\left\{ m,~K_{A}^{+}\left( m \right) \right\}\)
Answer» C. \(\left\{ m,~K_{A}^{-}\left( H\left( m \right) \right) \right\}\)
