In the field of cybersecurity, particularly in classical cryptography, understanding the concept of fields is important for comprehending the inner workings of cryptographic algorithms such as the AES block cipher cryptosystem. While the assertion that the field be considered as a set of numbers in which one can add, subtract and multiple but not divide

What is an elliptic curve and how is it defined mathematically?
Thursday, 03 August 2023
by EITCA Academy
An elliptic curve is a fundamental mathematical concept that plays a important role in modern cryptography, particularly in the field of elliptic curve cryptography (ECC). It is a type of curve defined by an equation in the form of y^2 = x^3 + ax + b, where a and b are constants. The equation represents
