Explain why nonforgeability and nonmutability imply nonrepudiation for digital signatures
What will be an ideal response?
The reason non-forgeability and non-mutability imply non-repudiation is that
a signature, SAlice(M), produced by Alice, is easily verifiable using publicly available infor
mation, and it is computationally infeasible for an attacker to have forged this signature
from scratch or to have transformed a different signature into this one (and have it still be
verifiable for the message M). So Alice must have been the one to produce this signature
and the message M must have been what she was signing when she did this.

Analyze the following code:
``` public class Test { public static void main(String[] args) { int n = 10000 * 10000 * 10000; System.out.println("n is " + n); } } ``` a. The program displays n is 1000000000000. b. The result of 10000 * 10000 * 10000 is too large to be stored in an int variable n. This causes an overflow and the program is aborted. c. The result of 10000 * 10000 * 10000 is too large to be stored in an int variable n. This causes an overflow and the program continues to execute because Java does not report errors on overflow. d. The result of 10000 * 10000 * 10000 is too large to be stored in an int variable n. This causes an underflow and the program is aborted. e. The result of 10000 * 10000 * 10000 is too large to be stored in an int variable n. This causes an underflow and the program continues to execute because Java does not report errors on underflow.
Given a folder with images in it, create an index HTML page with links to each image. Write a function that takes a string which is the path to a directory. You will create a page in the folder named index.html that should be an HTML page containing a link to every JPEG file in the directory. You will also generate a thumbnail (half the size) copy of each image. Use makeEmptyPicture to create a blank picture of the right size, then scale down the original picture into the blank picture. Name the new image “half-” + the original filename (e.g., if the original filename was fred.jpg, save the half-size image as half-fred.jpg). The anchor in the link to each full-size picture should be the half-size image.
