Assignment Content

For the assignment below assume the public key is $(17,2201).$ You can easily uncover the necessary primes without them being

provided.

Question $1$

Suppose a long message needs to be broken up into chunks. What is the largest number of bits each chunk can be$?11$

Blank

Question $2$

Suppose a ciphertext block has the integer value of $833.$ What is the associated plaintext message block? $($Hint your answer should

be a $10$ digit binary string$)$ Blank $1.$

Question $3$

Calculate the private key value d in the ordered pair $($d$,2201).1853$

Blank

Question $4$

Suppose a chunk has the bit string $11001101.$ The base $10$ equivalent of the binary string is $205.$ This value would be encrypted as

the value $423$
