Question

What is the difference between a restricted algorithm and a key-based algorithm?

a.

A restricted algorithm is a type of key-based algorithm.

b.

A restricted algorithm relies on the secrecy of the key while a key-based algorithm relies on the secrecy of the algorithm.

c.

A key-based algorithm relies on the secrecy of the key while a restricted algorithm relies on the secrecy of the algorithm.

d.

None of the above

Posted under Reverse Engineering

Answer: (c).A key-based algorithm relies on the secrecy of the key while a restricted algorithm relies on the secrecy of the algorithm. 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.
