WebSep 6, 2015 · This is the approach used in the influential book Concrete Mathematics by Graham, Knuth, Patashnik. This will give you 1/2 (mod3)=1/2. To work through your problem, you have a = 7 * (4/11) = 28/11, and b = 10. a / b = (28/11)/10 = 0.25454545... ⌊a/b⌋ = 0 b ⌊a/b⌋ = 0 * 0 = 0 a - b ⌊a/b⌋ = 28/11 - 0 = 28/11 This means your answer is 28/11. WebD e mod {(p - 1) x (q - 1)} = 1. 7d mod 60 = 1, which gives d = 43. The private key is = (43, 77) Step 6: A ciphertext message c is decrypted using private key . To calculate plain text m from the ciphertext c following formula is used to get plain text m. m = c d mod n. m = 37 43 mod 77. m = 9. In this example, Plain text = 9 and ...
