Which term describes encryption applied to data in motion (examples include WPA, IPsec, TLS)?

• A. Transport/communication encryption
• B. Data-at-rest encryption
• C. End-to-end encryption
• D. Disk encryption

Answer: (A)

Data in motion is the information being transmitted across networks. Encryption used during that transmission is called transport/communication encryption. Technologies like WPA, IPsec, and TLS all protect data as it travels between endpoints, across networks. Data-at-rest encryption, by contrast, protects stored information on disks or backups, not moving data. End-to-end encryption focuses on ensuring only the communicating endpoints can read the content, which is a related concept but the term that best describes encryption applied to data in transit in this context is transport/communication encryption.
