To answer this question, let's go through each option to understand why it is correct or incorrect:
Option A) Increased stability as the programs are protected against viral attack - This option is incorrect. While integrating cryptography into applications can provide security against certain types of attacks, it does not directly contribute to the stability of the programs. Stability is more related to the overall design and implementation of the software.
Option B) Enhanced reliability as users can no longer modify source code - This option is incorrect. Cryptography does not prevent users from modifying the source code of an application. It primarily focuses on protecting data and communications.
Option C) Reduced breaches of policy due to disclosure of information - This option is incorrect. While cryptography can help in protecting sensitive information, it does not directly address breaches of policy. Policy breaches are typically managed through access controls, user training, and other administrative measures.
Option D) Possible denial of service if the keys are corrupted - This option is correct. Integrating cryptography into applications relies on the use of encryption keys to encrypt and decrypt data. If these keys are corrupted or compromised, it can lead to a denial of service (DoS) situation where the encrypted data cannot be properly accessed or decrypted.
The correct answer is D) Possible denial of service if the keys are corrupted. This option is correct because if the encryption keys used in a cryptography system are corrupted, it can lead to a denial of service situation where the encrypted data cannot be properly accessed or decrypted.
