Each participant in a cryptographic system selects its own elliptic curve and verifies that the elliptic curve is sufficiently secure. A participant is represented by a handheld low memory device such as a smart card. A central facility is not required for key creation. The determination of whether an elliptic curve is sufficiently secure is made by counting the number of points on the curve and ensuring that this number is divisible by a prime number of at least a predetermined length. |
