An enterprising company F has a public RSA key (N, e) with N = 10160 + 478∗1080 + 45021e = 577a) The company claims that brute force breaking of an encrypted message will take eons. Give an estimate in years for the time a method based on brute force factoring of N will take using a computer that takes 10−9 seconds to test if a given integer divides Nb) The company plans to encrypt 4 digit PIN numbers by encrypting each digit separately and producing a vector [c1,c2,c3,c4] that will be publicly viewable as it is sent to the company website. They claim this will give virtually unbreakable security for the transmission of pin numbers. Are they right?c) Customer C follows the instructions and encrypts using the public key on each digit of their PIN to obtain the vector [W, X,Y, Z] withW = 84991392717999174792898555513265550 006006729444624292737466 85003923810540248034988599782458506 07491686144291541700091026279 38954960660726746337173475383576081 30X = 44363834090034912691385960301014412 582034604241958583369592 52879410438763718705392990335054063 06459442193574928145473560040 47390361551270219975991140676898596 35Y = 46094530942337725500972681223280433 502508738566494157428660 20265542723320395286408430734314104 01271865454223700394934378789 45947457893228944220409942560479817 53Z = 81742818801173905252292784873766387 797195090036482877135291 54258455350663856647605482586506244 93120097683557213425376697237 72391273587734666348320987370230834 87 What is the PIN for Customer C?
