What is an advantage of RSA over the DSA?
A.
It can provide digital signature and encryption functionality.
B.
It uses fewer resources and encrypts faster because it uses symmetric keys.
C.
It is a block cipher rather than a stream cipher.
D.
It employs a one-time encryption pad.
Explanation:
A: RSA can be used for data encryption, key exchange, and digital signatures. DSA can be used only for digital signatures.
This is not a good question. Since RSA and DSA both can using on Digital Signature and encryption . The answer is not clear enough to show the difference.
RSA (Ron Rivest, Adi Shamir and Leonard Adleman) can be used for data encryption, key exchange, and digital signatures.
DSA (Digital Signature Algorithm) can be used only for digital signatures.
