both Alice and Bob (protocol in page 338). Alice and KDC have A5 (hexa) as a shared key. Bob and KDC have 4B (hexa) as a shared key. Alice sends a request to KDC to generate a session key so it can communicate with Bob. KDC generates 56(hexa) as a session key. Alice intends to send 13 (hexa) as a message to Bob. For simplicity assume that the encryption and decryption operations are simply XOR operation of the key with the message. Answer the following.
1. What information does KDC send to Alice? Show as hex characters.
2. What information does Alice send to Bob? Show as hexa characters.

d = t // (24 * 3600) #calculate day and store in d variable  t= t % (24 * 3600)#calculate time and store in t variable  h = t // 3600#calculate hour and store in h variable  t %= 3600#calculate time and store in t variable  m=t // 60#calculate minutes and store in m variable  t%= 60#calculate time and store in t variable  s = t#calculate second and store in s variable  print("day:hour:minute:second= %d:%d:%d:%d" % (d,h,m,s))#print calculated value

Output:

Enter time value in seconds: 1239876

day:hour:minute:second= 14:8:24:36

Explanation:

Description of the above can be defined as follows:

  • In the above Python program code an input variable "t" is declared, which uses the input method to input value from the user end.
  • In the next step, "d, m, and s" is declared that calculates and stores values in its variable and at the last print, the method is used to print its value.
