Exercise 20

Tokens, smart cards, and biometric devices used for identification and authentication provide robust authentication of the individual by practicing which of the following principles?

A. multiparty authentication

B. two-factor authentication

C. mandatory authentication

D. discretionary authentication

Step 1 of 2

Robust authentication

Token, smart cards and biometric devices are all used for identification and authentication. These devices follow a technique which is known as “something you have/something you know”, where something you have is the information stored on the device like smart card, and something you know is the security code PIN for the device. This technique is called Two-Factor Authentication. It is the principle on which tokens, smart cards and biometric devices provide robust authentication.

Hence, the correct option is B. Two-Factor Authentication
