A Forward-Secure Digital Signature Based on Elliptic Curve

| Summary: | The forward-secure digital signature is an important digital signature scheme.It requires that even if the attackers have already been given a signature key by invading a system in t time，it still can’t forge signatures before time t.In other words，the forward-secure digital signature provides an assurance that any signatures in the previous periods are still valid before the key compromises.Based on the elliptic curve discrete logarithm problem and the factoring problem，a forward-secure digital signature scheme was put forward，and the safety and efficiency of the program was analyzed and proved systematically. |
