In the secret distribution phase, the designated participants can choose their own secret shares, and there is no need to establish a secure channel between the distributor and the participants;in the secret reconstruction phase, a designated participant must be involved in order to successfully recover the original secret. The analysis of the security and performance of the scheme shows that the proposed scheme is better than the existing scheme in terms of efficiency and security.展开更多
