What are eulers theorem used for?
Euler's Theorem is a fundamental result in number theory, which states that for any integer and a positive integer that are coprime (i.e., their greatest common divisor is 1), the following congruence relation holds: Here, is Euler's Totient Function, which counts the number of positive integers up to that are relatively prime to
What is the exponentiation function in the RSA cipher?
The RSA (Rivest-Shamir-Adleman) cryptosystem is a cornerstone of public-key cryptography, which is widely used for securing sensitive data transmission. One of the critical elements of the RSA algorithm is the exponentiation function, which plays a pivotal role in both the encryption and decryption processes. This function involves raising a number to a power, and then
