Hierarchical signature scheme based on elliptic curve digital signature algorithm
摘要
In this article, we have proposed a hierarchical signature scheme based on Elliptic Curve Digital Signature Algorithm. The motivation for our proposed signature scheme is from a scenario of a company in which a group of users is partitioned into hierarchical levels. If an author wants signature(s) on a message from the company, a threshold number of users from each level (or higher) can combinely sign the message. Our scheme is verifiable, computationally secure and efficient. We have given an explicit example for illustration purposes.
