Using RSA encryption with p=47, q=61, and e = 7, encrypt the following message in two-letter...
4. Suppose you wish to encrypt the message, M 42 using RSA encryption. Given a public key where p- 23 and q-11 and the relative prime e- 7. Find n, and show all necessary steps to encrypt your message (42). (Hint: check p.411 of the text for information on public key RSA) (5 points)
in RSA e= 13 and n = 100 encrypt message HOW ARE YOU DOING using 00 to 25 letter A to Z and 26 for space use different blocks to make p < n
Answer the following: We would like to encrypt the message "HOWDY” using RSA. To do this, we will encrypt each letter individually (H = 8,0 = 15, W = 23, D = 4, Y = 25). Show detailed steps for at least one letter Use p = 17, q = 23, e = 3, m =(8, 15, 23, 4, 25)
Using RSA cipher, public key e=3, private key d=7 Encrypt the following message “Hello there” Decrypt the previous message
Perform encryption and decryption using RSA algorithm for the following P= 5; q = 11, M= 9; e = ?
Digital Signature (5-5): In the course notes we looked at RSA for encryption and signatures (using exactly the same mathematical formula), and ElGamal for encryption. There has been several questions on using ElGamal for signature. The ElGamal encryption algorithm cannot be used for signatures but there are signature schemes that is based on discrete logarithm. (a) Search for simple explanation of the ElGamal signature scheme and DSA signature scheme (Hint: Wikipedia). Can these algorithms be used to encrypt a message?...
For the RSA encryption algorithm , do the following (a) Use p=257,q=337(n=pq=86609),b=(p-1)(q-1)=86016. Gcd(E,b)=1, choose E=17, find D, the number which has to be used for decryption, using Extended Euclidean Algorithm (b) One would like to send the simple message represented by 18537. What is the message which will be sent? (c) Decrypt this encrypted message to recover the original message.

C Programming - RSA encryption Hi there, I'm struggling with writing a C program to encrypt and decrypt a string using the RSA algorithm (C90 language only). It can contain ONLY the following libraries: stdio, stdlib, math and string. I want to use the following function prototypes to try and implement things: /*Check whether a given number is prime or not*/ int checkPrime(int n) /*to find gcd*/ int gcd(int a, int h) void Encrypt(); void Decrypt(); int getPublicKeys(); int getPrivateKeys();...
