What role does encryption play in maintaining confidentiality?

Encryption plays a crucial role in maintaining confidentiality by securing data from unauthorized access. When data is encrypted, it is transformed into a coded format that can only be interpreted or decrypted by authorized parties who possess the appropriate keys or credentials. This ensures that even if the data is intercepted or accessed without permission, it remains unreadable and protected, thereby safeguarding sensitive information from potential breaches.

The purpose of encryption aligns directly with the principle of confidentiality, which is fundamental to information security. By using encryption, organizations can ensure that confidential data—such as personal information, financial records, and proprietary business information—remains private and protected from prying eyes.

In contrast, other choices do not align with the primary function of encryption. For instance, sharing data openly would compromise confidentiality, while backdoor access would undermine the security that encryption aims to provide. Simplifying data management, while beneficial, does not directly relate to the confidentiality goal that encryption seeks to achieve.
