RSA cryptosystem is used to secure a shared key between two party A and B. the host A has selected n=35. a. Determine p and q two prime numbers such as n=p*q b. Determine the set of private and public key. c. A has selected e=17, determine the decryption key d. d. The message to be sent is m=33, determine the cipher C e. The receiving host needs to decipher the received message C, show how the decryption is completed using the square and multiply algorithm. f. The message is now m=155 and the encryption key is e=12. Conclude about the new cipher C1. RSA cryptosystem is used to secure a shared key between two party A and B. the host A has selected n=35. a. Determine p and q two prime numbers such as n=p*q b.

Answer rating: 100% (QA)

Solution a To find p and q you need to factorize n into two prime numbers One way to do this is to try dividing n by small primes until you find one t... View the full answer
