Kerberos is an authentication scheme that can be used to implement:
A.
Hash functions.
B.
Single Sign-On (SSO).
C.
Public key cryptography.
D.
Digital signatures.
Explanation:
The correct answer is “Single Sign-On (SSO).”. Kerberos is a third-party authentication
protocol that can be used to implement SSO. Answer “Public key cryptography” is incorrect
because public key cryptography is not used in the basic Kerberos
protocol. Answer “Digital signatures” is a public key-based capability, and answer “Hash functions”
is a one-way transformation used to disguise passwords or to implement
digital signatures.
