Number Theory in Discrete Mathematics Flashcards
is a branch of mathematics focused on the properties and relationships of numbers, particularly integers.
Number Theory
A number a is divisible by b if there is an integer c such
that a=bc.
DIVISIBILITY AND PRIME NUMBERS
- The largest positive integer that divides two integers
without leaving a remainder.
GREATEST COMMON DIVISOR (GCD)
A system of arithmetic for integers where numbers wrap
around upon reaching a certain value—the modulus.
a≡b (mod m) means m divides a−b.
MODULAR ARITHMETIC
Equations that seek integer solutions.
Example: ax+by=c, where x and y are integers.
DIOPHANTINE EQUATIONS
Uses properties of prime numbers and
modular arithmetic to encrypt and decrypt messages.
RSA Algorithm
Relies on the arithmetic of
elliptic curves over finite fields.
Elliptic Curve Cryptography
is integral to computer
science as it provides the mathematical
foundation for algorithms, data structures,
cryptography, and more.
Discrete mathematic
Concepts like graphs, sets, and functions provide
abstract models to design algorithms and data structures.
Abstract Structures
Discrete math instills rigor in problem-solving,
essential for ensuring the correctness and efficiency of algorithms.
Mathematical Rigor
Understanding combinatorics and number theory is key to analyzing the computational complexity of algorithms.
Computational Complexity
Number theory ensures the robustness of cryptographic protocols, vital for secure communication in computing systems.
