Data encryption during transmission is a fundamental method for ensuring transmission security. By encrypting data, the information being sent over communication channels is converted into a format that is unreadable to unauthorized users. This means that even if data packets are intercepted by a third party, they would not be able to understand the content without the appropriate decryption key. Encryption uses algorithms to create a secure channel, providing a layer of protection against eavesdropping and data breaches, which is critical in safeguarding sensitive information during transmission.

Other methods, such as using easily accessible communication channels or minimizing equipment maintenance, do not directly contribute to the security of the data being transmitted. Easy access can lead to vulnerabilities, while equipment maintenance is more focused on operational efficiency rather than security. Random signal modulation can have its uses in some contexts, but in general, it is not as robust or commonly employed as encryption for securing data during transmission.
