What is the primary purpose of encryption in Navy communications?

The primary purpose of encryption in Navy communications is to protect information from unauthorized access. In military operations, safeguarding sensitive data is crucial for maintaining operational security and ensuring that vital information does not fall into the hands of adversaries or unauthorized individuals. Encryption scrambles the data, making it unreadable without the proper decryption key, thus preventing interception and ensuring that only authorized personnel can access the relevant information.

This function is essential in maintaining the confidentiality of communication, particularly when sensitive information could impact the safety and effectiveness of military operations. While other options may address different aspects of data handling and communication (such as speed and storage), the primary goal of encryption is specifically focused on safeguarding against unauthorized access to sensitive information.
