Question

Which of the following are true for side channel attacks?

a. They exploit weaknesses in cryptographic algorithms.
b. They exploit weaknesses in algorithm implementations.
c. They work with encrypted messages that are captured in transit.
d. None of these.

Answer 1

Answer:

The answer is option 'b'.

Explanation:

They exploit weaknesses in algorithm implementation

Answer 2

None of the given options...., is true for a side channel attacks.

Explanation:

A side-channel is a means by which confidential information about the plain text is inadvertently leaked to an attacker, who then exploits the information to further his attacks.  

In the field of computer security, the side-channel attack is on the basis of information obtained from the implementation of the 'computer system', rather than on the weaknesses of the implemented algorithm itself. Error reporting is a common type of side-channel in real cryptographic systems.
