Key Concepts

RSA Algorithm

The RSA algorithm is an asymmetric cryptographic method that involves key generation, encryption, and decryption. Its security is based on the mathematical difficulty of factorizing large composite numbers that are the product of two primes. In RSA, a public key is used for encryption and a private key for decryption.

Public Key Cryptography

Public key cryptography involves a pair of keys: one public and one private. The public key is openly distributed and used for encrypting messages, while the private key is kept secret and used for decrypting them. This paradigm enables secure communication without the need for secure key exchange.

Modular Arithmetic

Modular arithmetic deals with integers and a modulus, where numbers wrap around once they reach the modulus value. In RSA, modular arithmetic ensures that computations, such as exponentiation and multiplicative inverses, are confined within a specific range, which is critical for the algorithm's functionality.

Euler's Totient Function

Euler's Totient Function (?(n)) counts the number of integers less than n that are relatively prime to n. It is essential in RSA for computing the private decryption key, as it is used to find the multiplicative inverse of the public exponent modulo ?(n).

Modular Exponentiation

Modular exponentiation is the process of finding the remainder when an integer raised to a large power is divided by a modulus. This computational technique is fundamental in RSA for both encrypting and decrypting messages efficiently while dealing with large numbers.
