Of the following, which is not a weakness of symmetric cryptography?
A.
Limited security
B.
Key distribution
C.
Speed
D.
Scalability
Explanation:
Symmetric cryptography is generally fast and hard to break, depending
on key size. Its weaknesses are key distribution that requires a secure mechanism to
deliver the key properly, scalability (each pair of users needs a unique pair of
keys) and limited security, which can only provide confidentiality.
