Is the exchange of keys in DHEC done over any kind of channel or over a secure channel?
In the field of cybersecurity, specifically in advanced classical cryptography, the exchange of keys in Elliptic Curve Cryptography (ECC) is typically done over a secure channel rather than any kind of channel. The use of a secure channel ensures the confidentiality and integrity of the exchanged keys, which is crucial for the security of the

In EC starting with a primitive element (x,y) with x,y integers we get all the elements as integers pairs. Is this a general feature of all ellipitic curves or only of the ones we choose to use?
In the realm of Elliptic Curve Cryptography (ECC), the property mentioned, where starting with a primitive element (x,y) with x and y as integers, all subsequent elements are also integer pairs, is not a general feature of all elliptic curves. Instead, it is a characteristic specific to certain types of elliptic curves that are chosen
