Implement a Message Authentication Code program in either C/C++ or Python.

1. Accept a message as keyboard input to your program.

2. Accept a secret key for the sender/recipient as keyboard input to your program.

3. Your hash function H() is simply the checksum. To compute the checksum, you add all the characters of the string in ASCII codes. For example, the checksum of a string "TAMUC" would be 84 + 65 + 77 + 85 + 67 = 378.

Concatenate the secret key of the sender/recipient (from step 2) and the message (from step 1) and compute the checksum of the concatenated string. For ASCII codes, refer to the following website:

http://www.asciitable.com

4. Accept a secret key for the attacker as keyboard input to your program.

5. The attacker modifies the message from step 1. The original message can be modified any way you want.

6. Concatenate the secret key of the attacker (from step 4) and the modified message (from step 5) and compute the checksum of the concatenated string.

7. Concatenate the secret key of the sender/recipient (from step 2) and the modified message (from step 5) and compute the checksum of the concatenated string.

8. Compare the checksum from step 7 and the checksum from step 6. See if they match or not.

9. Compare the checksum from step 3 and the checksum from step 6. See if they match or not.

NOTE: your program should have separate functions for the checksum and the message modification by the attacker.

Write a Java code to represent a

1. Date class. As date class is composed of three attributes, namely month, year and day; so the class contains three Data Members, and one method called displayDate() which will print these data members.

2. Test the Date class using main class named DateDemo.
   • Create two objects of date class.
   • Initialize the data fields in Date class using the objects,
   • invoke the method displyaDate().

Draw an EER model of given scenario

We wish to create a database for a company that runs training courses. For this, we must store data about the trainees and the instructors. For each course participant (about 5,000),identified by a code, we want to store her social security number, surname, age, sex, place of birth, employer’s name, address and telephone number, previous employers (and periods employed), the courses attended (there are about 200 courses) and the final assessment for each course. We need also to represent the seminars that each participant is attending at present and, for each day, the places and times the classes are held. Each course has a code and a title and any course can be given any number of times. Each time a particular course is given, we will call it an ‘edition’ of the course. For each edition, we represent the start date, the end date, and the number of participants. If a trainee is self-employed, we need to know her area of expertise, and, if appropriate, her title. For somebody who works for a company, we store the level and position held. For each instructor (about 300), we will show the surname, age, place of birth, the edition of the course taught, those taught in the past and the courses that the tutor is qualified to teach. All the instructors’ telephone numbers are also stored. An instructor can be permanently employed by the training company or freelance.
