What is end-to-end encryption designed to ensure?

• A. Data is encrypted on the sender's device only
• B. Data is decrypted on the sender's device only
• C. Data is encrypted on the sender's device and decrypted only on the recipient's device
• D. Data is publicly available during conversion

Answer: (C)

End-to-end encryption is a security measure that ensures that data is encrypted on the sender's device and can only be decrypted on the recipient's device. This means that the data remains secure while it is being transmitted over a network, preventing unauthorized access by third parties, including service providers and potential eavesdroppers. By ensuring that only the sender and the intended recipient can read the messages, end-to-end encryption protects the confidentiality and integrity of the data being exchanged. This model addresses concerns over data privacy and security, especially in contexts where sensitive information is being communicated. Therefore, this approach is critical in applications like messaging, where user data must be shielded from external threats. The other choices do not embody the full concept of end-to-end encryption as they either limit the encryption to only the sender's device or suggest that the data is accessible to others during the conversion process, which contradicts the very premise of end-to-end encryption.
