Cryptography Lecture 3 - Stream ciphers random number generators
Pseudo-Random Number Generator (PRNG). • Sender and receiver must generate exactly the same key stream from the seed so the generator is deterministic.
Generating Constrained Random Data with Uniform Distribution

An Improved Ziggurat Method to Generate Normal Random Samples
Flexibility is enhanced by using a plug-in uniform random number generator. An efficient double-precision version of the ziggurat algorithm is developed that
Random Numbers in Python
If there is a program to generate random number it can be predicted thus it is not truly random. • Random numbers generated through a generation algorithm are

Python currently uses theMersenne Twisteras its core random number generator; U = random random() It produces at double precision (64 bit) 53-bit precision (?oating) and has a period of 219937 1 (a Mersenne prime number) The Mersenne Twister is one of the most extensively tested random number generators in existence

For example suppose we wanted to generate a value in the range -5 through 10 inclusive The formula indicates we should use this code: rand() (10 -(-5) + 1) + (-5) Simplifying gives us: rand() 16 –5 See random_numbers py 23 List Comprehensions Python features a very compact syntax for generating a list called a list comprehension

A generator that has the maximum possible period is called a full-period generator Lower autocorrelations between successive numbers are preferable Both generators have the same full period but the first one has a correlation of 0 25 between x n-1 and x n whereas the second one has a negligible correlation of less than 2-18

What are the different ways to generate a random number in python?
- Python makes it very easy to generate random numbers in many different ways. In order to do this, you’ll learn about the random and numpy modules, including the randrange, randint, random, and seed functions. You’ll also learn about the uniform and normal functions in order to create more controlled random values.
What is the randint function?
- The randint () function returns an integer value (of course, random!) between the starting and ending point entered in the function. This function is inclusive of both the endpoints entered. The function returns the number 5 as a random output.
What is the randbelow function?
- The randbelow ()function is inclusive of both the limits entered in the function. The use of random test cases is immense in programming. The built-in functions of several programming languages make it easier for us- the programmers to execute millions of arbitrary test cases and develop an efficient and accurate program.
What is the range for the randint() method?
- The random () method in random module generates a float number between 0 and 1. The randint () method generates a integer between a given range of numbers. We can use the above randint () method along with a for loop to generate a list of numbers.
