Problem 1: Implement ElGamal system Your code will accept prime p and a generator a. Then a user will pick either key generation (k), message signature (s) or message verification (v) option. Key generation: program will randomly pick a secret X₂ and output private and public key. Message signature: user will provide m. Program will use random k. You should use EEA to computer k-¹. Output (S₁, S2). Instead of using H(m), just use m. So for us H(m)-m identity function. This will make computations slower as value of m can be large. Message verification: user provides all required information and program will decide if the signature is valid.

Experiment 1: IMPLEMENTATION OF CAESAR CIPHER Objective: To implement the simple substitution technique named Caesar cipher using C+ language. Theory: To enerypt a message with a Caesar cipher, each letter in the message is changed using a simple rule: shift by three. Each letter of the message is shifted a fixed distance (3 for example) down the alphabet, A becomes D, B becomes E, and so on. For the last letters, we can think of alphabet as a circle and "wrap around", W becomes Z. X becomes A, Y becomes B, and Z becomes C. To change a message back, cach letter is replaced by the one three before it.

STEP-2: Read the key value from the user. STEP-3: If the key is positive then encrypt the text by adding the key with each character in the plain text. STEP-4: Else subtract the key from the plain text. STEP-5: Display the…

Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Devices (DID2) 01 10 Sensors (S1S2) 00 01 10 11 11 00 Write a program to control these two devices according to the values of sensors. Each group should submit a zip file which contains the following files Code file: (assembly language code) - Simulation file Report (pdf file) (details of every single step in the code, also what have you learned from this experiment)
vvvHarry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output.Input: 4 2 2Output4Harry has a big wall clock, that got hit while he was playing.

Consider you have 5 types of tree which are “A”, “B”, “C”, “D”, and “E”. Now writea java program to plant these trees in a 500m length road providing random gapbetween two trees. Remember, the gap between two trees must be an integer valueand it will be greater than 10 but less than 25. You also have to remember similartypes of tree cannot be planted one after another.
1.Implement Thirsty problem using semaphore . Scenario:To drink, a thirsty person must have three things; water, ice and a glass.There are three thirsty people, each having a different one (and only one) of the three required items. A fourth person, a server has unlimited supply of all three items. If nobody is drinking, the server places two of the three items (chosen at random) onto table. Thirsty person who can make a drink from those two items will pick them up and drink a glass of ice water. When done, thirsty person will notify the server and the process will repeat.
Using JAVA solve the below problem Amitabh had a magical cat. That cat once fell down an empty well. As the walls of the well were not completely vertical, the cat could climb up the well. In one day, the cat can climb 1 unit height and the height of the well is h units. The cat starts at the bottom. Every day, a cat would divide into 2 cats. One of them would climb up 1 unit. The other would wait for help. But while waiting it would fall asleep and roll down 1 unit, unless it is already at the bottom, in which case it just remains there. When a cat would reach the top, it would run home toAmitabh. (Schrodinger doesn't know that some of the cats are in a well and so he can't rescue them). It has been d days since the cat fell into the well. How many cats would come out of the well today? You would notice that the number of cats grows very large with each passing day, so output the answer modulo 10^9+7. d = 0 means that the cat has fallen just now and so there's just one cat at the…
Question 2: Encoding Cryptography is the study of trying to create secure information by obscuring the original message. One simple encryption method is to substitute letters from the original message with other letters. To make it harder to decrypt the hidden message, we may also remove clues such as the length of the words in the message and any punctuation or capitalization. Write a function encode that consumes a string message. The function produces a string which is encrypted according the following procedure: * Only the letters from the original message will be encrypted. Other characters such as spaces, punctuation, numeric digits, etc. are not included in the encrypted message at all. * The encrypted message will only contain uppercase letters. * Each letter will be replaced by the uppercase letter at the opposite end of the English alphabet. In other words, A or a will become Z, B or b will become Y, C or c will become X, ..., Z or z will become A. * The encrypted message…
