Program Plan Intro

Balanced Multiple Delimiters

Program Plan:

  • Include required header files
  • Declare function prototype
  • Inside “main ()” function,
    • Declare a variable “strng”.
    • Get a string from the user.
    • Check if the Boolean function “is_Balanced ()” returns true.
      • If the condition is true then the string has balanced delimiters.
      • If the condition is not true then the string does not have balanced delimiters.
  • Inside “is_Balanced ()” function,
    • Declare a Boolean variable “status”.
    • Declare a character variable “expected”
    • Create an object for stack.
    • Loop each character.
      • Switch to the character.
        • If left parenthesis is detected,
          • Push it into the stack using the function “push ()”.
        • If left braces is detected,
          • Push it into the stack using the function “push ()”.
        • If left bracket is detected,
          • Push it into the stack using the function “push ()”.
        • If right parenthesis or right bracket or right braces is detected,
          • Get the top element from the stack and store it in a variable “expected”
        • Check if the expected character is not equal to “str[k]”.
          • Assign “false” if the condition is true.
          • Else, pop the element
    • Check if the stack is empty and assign “true”. Else, assign “false”.
    • Return the variable “status”.

Compare the security services provided by a digital signature (DS) with those of a message authentication code (MAC). Assume that Oscar can observe all messages sent between Rina and Naseem. Oscar has no knowledge of any keys but the public one, in the case of DS. State whether DS and MAC protect against each attack and, if they do, how. The value auth(x) is computed with a DS or a MAC algorithm. In each scenario, assume the message M = x#####auth(x). (Message integrity) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message M, and then sends M in cleartext to Naseem. Oscar intercepts the message and replaces “Mark” with “Oscar.” Will Naseem detect this in the case of either DS or MAC? If yes, how will Naseem detect it? If not, why? (Replay) Rina has the textual data x = “Transfer $1000 to Mark” to send to Naseem. To ensure the integrity of the data, Rina generates auth(x), forms a message…
