Question

What is the difference between restricted algorithms and key-based algorithms in cryptography?

a.

Restricted algorithms use keys while key-based algorithms do not.

b.

Restricted algorithms are more secure than key-based algorithms.

c.

Restricted algorithms rely on the secrecy of the algorithm while key-based algorithms rely on the secrecy of the key.

d.

None of the above

Posted under Reverse Engineering

Answer: (c).Restricted algorithms rely on the secrecy of the algorithm while key-based algorithms rely on the secrecy of the key. Explanation:Restricted algorithms rely on the secrecy of the algorithm itself, while key-based algorithms rely on the secrecy of the key used to encrypt and decrypt messages.
