A.

Differential power analysis

B.

Electromagnetic emission

C.

Corruptive

D.

Timing

Explanation:

Some examples of side-channel attacks that have been carried out on smart cards are differential power analysis (examining the power emissions released during processing), electromagnetic analysis (examining the frequencies emitted), and timing (how long a specific process takes to complete).  These types of attacks are used to uncover sensitive information about how a component works without trying to compromise any type of flaw or weakness.  They are commonly used for data collection.
