Chapter 6, Problem 6.11E

(Bubble Sort) The bubble sort presented in Fig. 6.15 is inefficient for large arrays. Make the following simple modifications to improve its performance.

  1. After the first pass, the largest number is guaranteed to be ¡n the highest-numbered element of the array; after the second pass, the two highest numbers are “in place,” and so on. Instead of making nine comparisons on every pass, modify the bubble sort to make eight comparisons on the second pass, seven on the third pass and so on.
  2. The data in the array may already be in the proper or near-proper order, so why make nine passes if fewer will suffice? Modify the sort to check at the end of each pass whether any swaps have been made. If none has been made, then the data must already be in the proper order, so the program should terminate. If swaps have been made, then at least one more pass is needed.

Using R language
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…
