Question

What is euler's totient function in network security?

Answer 1

Answer:

Euler's totient function is a multiplicative function, meaning that if two numbers m and n are relatively prime, then φ(mn) = φ(m)φ(n). This function gives the order of the multiplicative group of integers modulo n (the group of units of the ring ℤ/nℤ). It is also used for defining the RSA encryption system.
