Question:
Describe any THREE characteristics of what might be regarded as a good encryption algorithm. Two of the modes under which a symmetric encryption algorithm can operate are described by the following equations:
(i) Identify the modes of operation and explain the meaning of all terms in the above equations.
(ii) Explain why a practical implementation of mode (2) should require the use of mode (1) during the initial phase of the dialogue. [6 marks]
(c) Explain the meaning of the terms message integrity and authentication in the context of network security. Describe how public key encryption technology can be used to implement
(i) a message integrity protocol and
(ii) an authentication protocol.
