Solve using discrete math methods and terms

Cryptography In this project, you will get some experience encrypting and decrypting simple messages. Affine Cypher Define an encryption function f as below f(p) = (3p 17) mod 26 . Use this function to encrypt the message "BEWARE OF ROGUE MANDRILLS Phd the decryption function and use it to decrypt the message "WMD APTXQDWD ADTKDORAHT RQD HE WHLHZ" [Include both the decryption function and the decrypted message in your report.] An affine cipher, in general, uses a function of the form f(p) (ap+b) mod 26 with gcd(a, 26-1. . The message below was encrypted with some a ffine cvpher. Can you crack the code and find the function that encrypted it? [Include both the encryption function and the decrypted message in your report.] "SRVYLOYBV VNY BELYRVNYOYQ TYHSFYLU VWRSINV" RSA Cryptosystem Suppose an RSA-style cryptosystem is set up with public key (3247, 13) and private key (3247, 1637) . Use the public key to encrypt the message "NUECES . Use the private key to decrypt the message 10142914 858. Alice, Bob, Chanique, and Daisuke all have the following public keys. Name TL 3 6497 23 17 291 Bob Chanique 12707 Daisuke 298719 Below is a message encrypted by one of the people above, using their private key. Deter- mine who sent it, and what the message says. 6091 11437 12002 (continued on next page)
