What does the term "end-to-end encryption" ensure in the context of CANES?

• A. Data is encrypted on the sender's side and decrypted by the intended recipient
• B. Data is stored securely on a central server
• C. Data is accessible to multiple users for collaboration
• D. Data is compressed for faster transmission

Answer: (A)

The term "end-to-end encryption" in the context of CANES means that data is encrypted on the sender's side and only decrypted by the intended recipient. This method ensures that the information remains confidential and secure throughout its journey across networks. No intermediate parties, including service providers or potential interceptors, can access the plaintext of the data during transit. By encrypting the data before it leaves the sender and only allowing decryption by the intended recipient, end-to-end encryption guarantees that privacy is maintained and unauthorized access is prevented. This security model is particularly important in scenarios where sensitive or classified information is communicated, ensuring that only the intended parties can read and understand the transmitted content. While other options touch on aspects of data handling, they do not align with the specific promise of end-to-end encryption, which focuses uniquely on the confidentiality and integrity of data during transmission.
