Consider the RSA cryptosystem. If we take p=11;q=17 then: (3 marks) a) What could be the possible value of "e"? (1 marks) b) Calculate a suitable "d" for the "e" you have selected above? ( 1 mark) c) If our message is "M =88" encryption and decryption using the values of "e" and "d" calculated above? ( I mark) - Question 2: a- Briefly describe the Caser cipher? ( 1 marks) b- What are hash functions? list some of the best-known hash functions and what they are used for ( at least 2 uses) ? ( 1 marks)
