The elliptic curve cryptography (ECC) uses elliptic curves over the finite field 𝔽p (where p is prime and p > 3) or 𝔽2m (where the fields size p = 2_m_). This means that the field is a square matrix of size p x p and the points on the curve are limited to integer coordinates within the field only.

The process works by using algorithms and cryptographic keys to encrypt and decrypt data.
