Detailed explanation-1: -Elliptic curve cryptography is chosen to respond to the low memory resources available for the low level devices of a SCADA network (e.g., PLCs), and also because it can achieve the same level of security as other cryptographic algorithms using smaller sizes for the secure keys.
Detailed explanation-2: -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-3: -The biggest difference between ECC and RSA/DSA is the greater cryptographic strength that ECC offers for equivalent key size. An ECC key is more secure than an RSA or DSA key of the same size.
Detailed explanation-4: -When it comes to performance at 128-bit security levels, RSA is generally reported to be ten times slower than ECC for private key operations such as signature generation or key management. The performance disparity expands dramatically at 256-bit security levels, where RSA is 50 to 100 times slower.
