Dynamic Multi-secret Sharing Scheme with Updatable Sub-secret
摘要
Abstract
This paper presents a dynamic multi-secret sharing scheme based on Elliptic Curves Cryptosystem(ECC). The sub-secrets of participants can update periodically. The sharing secrets and a participant can be added or deleted freely. This scheme is a multi-use verifiable secret sharing scheme, which can share several secrets in one secret sharing process. A secure channel between participants and the dealer does not need because of using signcryption algorithm on elliptic curve in the scheme. It is a secure and practical scheme.关键词
