1) Shift Cipher a) Encode JAVA with shift 9 b) Decode 03 0 5 05 04 with a shift of 17 2) Affine a) Encode: MATH with 5 + 7 ( 26) b) Decode: KNIO if you know it was encoded with 7 + 8 ( 26) 3) RSA Suppose we want to choose = 3 and = 7 a) Compute ,(),() b) What are the possible values for public key e? c) Find the inverses for your list from b d) What are all the possible sets of keys? 4) RSA You know the public key (11, 85) which was encoded based on the (85) totient Break the code and decrypt the message: 45 44 22
