Detailed explanation-1: -Elliptical curve cryptography (ECC) is a public key encryption technique based on elliptic curve theory that can be used to create faster, smaller and more efficient cryptographic keys.
Detailed explanation-2: -With a 112-bit strength, the ECC key size is 224 bits and the RSA key size is 2048 bits. The most popular signature scheme that uses elliptic curves is called the Elliptic Curve Digital Signature Algorithm (ECDSA).
Detailed explanation-3: -The foremost benefit of ECC is that it’s simply stronger than RSA for key sizes in use today. The typical ECC key size of 256 bits is equivalent to a 3072-bit RSA key and 10, 000 times stronger than a 2048-bit RSA key! To stay ahead of an attacker’s computing power, RSA keys must get longer.
Detailed explanation-4: -It works on the very same way. The only difference is the group where you do the math. In Elliptic Curve Cryptography the group is given by the point on the curve and the group operation is denoted by +, while in the standard Diffie-Hellman algorithm the group operation is denoted by ⋅.
