It is enciphered using the rule
R (m)=m (mod 91)
The resulting ciphertext is ( 73,14,23,73,23)
Verify the rule given satisfy the condition for an RSA cipher.
Using the repeated squaring technique decipher the ciphertext and find the message
Use mathematical induction to prove that
E 1/r(r+1)(r+2)=n(n+3)/4(n+1)(n+2) for n+1,2,3,.......
An RSA cipher is decoded. A summation is calculated. The solution is detailed and well presented.
