The alphabet with 37 symbols consists of the letters A, B, ... , Z having nu- merical equivalents 0, 1, ... , 25, and digits 0, 1, ..., 9 having numerical equivalents 26, 27, ..., 35, and blank space having numerical equivalent 36. Using Mathematica, Matlab or a similar software perform the following steps: a. Factorize n=p.9 = 239138087611441. b. Let u be equal to your student ID number written backwards, and with all zeros replaced by ones. E.g. if your ID=1930040, then u = 1411391 Choose your encryption exponent e being the largest appropriate number which is smaller than or equal to u. c. Find the decryption exponent d. d. Find the corresponding size k of blocks for the plaintext messages. e. The plaintext T consists of u followed by two letters of your initials, that is, by the first letter of your given name and then the first letter of your family name. Find its numerical equivalent t. f. Find the encryption s of t. g. Find the word S corresponding to s. h. Decrypt s getting t
