Final answer:
Digital signatures ensure the security of resources by verifying the authenticity and integrity of data, but they do not directly ensure input completeness, validity, or accuracy, which are concerned with the presence, correctness, and precision of the initial data.
Step-by-step explanation:
Digital signatures primarily serve to ensure the authenticity and integrity of digital communications and data. They are a cryptographic means for ensuring the security of resources, and making sure that messages or documents have not been altered in transit. When examining the control goals addressed by digital signatures, it is evident that they do not directly ensure input completeness, validity, or accuracy.
Input completeness refers to the goal that all necessary data is present. Input validity is about the data being correct and appropriate for the intended use. Finally, input accuracy means that the data precisely reflects the real-world values it represents. While digital signatures can indirectly support these goals by maintaining the integrity of the input through transit, they do not have a direct role in verifying the initial completeness, validity, or accuracy of the input data before it is signed.
Therefore, digital signatures address the following control goals except for ensuring input completeness (2), ensuring input validity (3), and ensuring input accuracy (4).
