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.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
