基于门限秘密共享的自证明公钥分发方案

针对分布式网络的应用需求，结合门限秘密共享的思想和自证明公钥的基本原理，提出分布式环境下椭圆曲线自证明公钥分发方案。实现用户与分布式密钥分发中心交互生成自证明公钥的过程。与现有同类方案相比，该方案不需要组合器，能增强可用性，减少密钥分发的计算开销和通信开销，并提高密钥的随机性。

Distribution Scheme of Self-certified Public Key Based on Threshold Secret Sharing

To meet the demand of the distributed networks, this paper presents an ECC-based self-certified public key distribution scheme under distributed environment by combining the threshold secret sharing scheme and the self-certified public key. It realizes the process that user can generate its self-certified public key with the distributed key distribution center. Compared with the existing schemes alike, the scheme does not rely on the combiner so as to increase the scheme＇s usability and reduce the computation and communication costs of the key distribution. Furthermore, the scheme also increases the randomness of the key.
