C) A key
D) Work factor

Quizplus · Accepted Answer

Work factor is a term that refers to the number of resources required to carry out a specific task. In the context of cryptography, the work factor is the amount of effort (usually measured in time or computational power) required to decrypt a message when the key or algorithm is not known. Therefore, the correct answer is D. Codes, algorithms, and keys are all relevant to cryptography, but they do not directly relate to the work factor.
