R1. Message confidentiality: It is the property where the message sent which is intended for the receiver should not be interpreted by any intruder in between and only the receiver should understand the contents of the message Message Integrity: It is the property where the message sent by the sender to the receiver should reach the receiver without any intruder or the network manipulating or altering its contents before it reaches the receiver. We can have integrity without confidentiality and confidentiality without integrity. They are two important properties for secure communication. An encrypted message that is altered by a intruder can be transmitted and will have message integrity but no confidentiality. Also a message sent to the receiver can be decrypted by a intruder and then transmitted. R4. Here the intruder has an encrypted and decrypted version of a message therefore the intruder can mount a known-plaintext attack.
