. Exercise 1.5.Exercise 1.5As we learned in this chapter, modular arithmetic is the basis of many cryptosystems.
As a consequence, we will address this topic with several problems in this and upcoming chapters.Compute the result without a calculator:. 15 29 mod 13. 2 29 mod 13.
2 3 mod 13. −11 3 mod 13The results should be given in the range from 0,1, modulus-1. Briefly describe the relation between the different parts of the problem. SolutionThis solution is verified as correct by the official manual.We can compute these by reducing the individual terms (since all members of an equivalence class behave the same), performing the arithmetic and then reducing the result:1.2.3.4.
Announcements.(Apr 16) The solutions to PS4 and PS5 are now posted. See below.
(Apr 2) A checklist of topics for the final exam is. (Apr 2) Finals Practice Exam has been posted. I willdiscuss this in the review session which will take place from 1-2pm on Monday, April 2 tentatively at IB 370.Please remember to submit the solutions to PS5during the review session or (if you cannot make it) at theinstructor's office (slip it under the door). (Mar 24) The final problem set (PS5) has been posted. It is due Monday, April 2 at 1pm in my office CCT 3073.
(Feb 20) Solutions to Problem sets 1 and 2 have been posted - see below in the section on 'Problem Sets'. Go over the previous (and future!) problem setsto prepare for the midterm!.
