So, you can use any random number generator (that is cryptographically strong) and generate a number big enough. In the case of the public key, it is a point (x and y coordinates) over a certain ECC curve. See in the section below the ECC curves approved by NIST. See more See below a table that shows the NIST-approved ECC curves and the security strength that can be achieved in each case. Notice that different curves will have different levels of security. One reason why the popularity of … See more The protection against a brute force attack for ECC is the same as other ciphers: to have a big keyspace. The bigger the key is in bits, the better. Just also consider that the bigger the keys … See more ECC curves are attractive to use because they can achieve the same security strength as other standards like RSA but use a smaller key size. As a result, the operations with ECC … See more ECC can be used for the same applications as the rest of public-key algorithms: 1. Encryption/Decryption 2. Digital signatures 3. … See more
