how can cryptography provide confidentiality and integrity across both time and space? (choose all that appy)

A
B
D
Since much of the Internet is carried on long-haul backbone circuits that go via satellite, encryption is used to protect data while being transmitted
via radio through space to and from the satellite and ground stations. Without encryption, anybody could receive these signals and break out the
data being exchanged.
с
0 Encrypting a file for storage ensures that it cannot be read or tampered with by unauthorized users or processes (which do not have the key); later,
authorized users with the key can read the file.
□
By protecting data in transit (via Internet or other means), it protects data when en route between two or more physically separated points (in
space).
Despite traveling at the speed of light, Internet traffic takes time to go from one user's system to another (i.e. from a client to a server); thus,
encryption protects the data in motion during this time.
