Question

____ is the amount of effort (usually in hours) required to perform cryptanalysis on an encoded message so that it may be decrypted when the key or algorithm (or both) are unknown.

Answer 1

Work Factor

Step-by-step explanation:

Work factor is a description where time is relative to processing power.

Time complexity, and work factor are used to describe processing power.It is quantitative system of measurements.

It require crypt analysis to encode message.
