What determines the strength of a secret key within a symmetric key cryptosystem?
A.
A combination of key length, degree of permutation, and the complexity of the data-encryption algorithm that
uses the key
B.
A combination of key length, initial input vectors, and the complexity of the data-encryption algorithm that
uses the key
C.
A combination of key length and the complexity of the data-encryption algorithm that uses the key
D.
Initial input vectors and the complexity of the data-encryption algorithm that uses the key
Explanation:
The strength of a secret key within a symmetric key cryptosystem is determined by a combination of key length,
initial input vectors, and the complexity of the data-encryption algorithm that uses the key.
