Chapter 11, Problem 12PP
Solution to
To combat election fraud, your city is instituting a new voting procedure. The ballot has a letter associated with every selection a voter may make. A sample ballot is shown.
1. VOTE FOR MAYOR
A.
| Pincher, Penny ▢ |
B.
| Dover, Skip ▢ |
C.
| Perman, Sue ▢ |
2. PROPOSITION 17
D.
| YES ▢ |
E.
| NO ▢ |
3. MEASURE 1
F.
| YES ▢ |
G.
| NO ▢ |
4. MEASURE 2
H.
| YES ▢ |
I.
| NO ▢ |
After submitting the ballot, every voter receives a receipt that has a unique ID number and a record of the voting selections. For example, a voter who submits a ballot for Sue Perman, Yes on Proposition 17, No on Measure 1, and Yes on Measure 2 might receive a receipt with
| ID 4925 : CDGH |
The next day the city posts all votes on its Web page sorted by ID number. This allows a voter to confirm their submission and allows anyone to count the vote totals for themselves. A sample list for the sample ballot is shown.
| 4925 | CDGH |
| 4926 | AEGH |
| 4927 | CDGI |
| 4928 | BEGI |
| 4929 | ADFH |
Write a program that reads the posted voting list from a file and outputs the percent of votes cast for each ballot item. You may assume that the file does not have any header lines. The first line will contain a voter ID and a string representing votes. Define a class named Voter that stores an individual’s voting record. The class should have a constructor that takes as input a string of votes (for example, “CDGH”), a voter ID, and accessor function(s) that return the person’s ID and vote for a specific question. Store each Voter instance in an array or

- Using R languagearrow_forwardCompare 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?

- Security in general means the protection of an asset. In the context of computer and network security, explore and explain what assets must be protected within an online university. What the threats are to the security of these assets, and what countermeasures are available to mitigate and protect the organization from such threats. For each of the assets you identify, assign an impact level (low, moderate, or high) for the loss of confidentiality, availability, and integrity.

It should have one private instance variable for the name of the animal, and one for its hunger status (fed or hungry). Add methods for setting and getting the hunger satus variable, along with a getter for the name. Consider how these should be named for code clarity. For instance, using a method called hungry () to make the animal hungry could be used as a setter for the hunger field. The same logic could be applied to when it's being fed: public void feed () { this.fed = true; Furthermore, the getter for the fed variable could be named is Fed as it is more descriptive about what it answers when compared to get Fed. Keep this technique in mind for future class designs. Zoo (10) Now we have the animals designed and ready for building a little Zoo! Build a class…arrow_forward
