Batch efficient distributed key generation method in asynchronous environment

The invention discloses a batch efficient distributed key generation method in an asynchronous environment. The method is characterized by comprising the following steps: designing an asynchronous verifiable information spreading protocol AVID-D with honest party discourse right; designing a parallel asynchronous verifiable information spreading protocol n-(n, t)-AVIDs with interruption availability by combining MVBA and a locking mechanism on the basis of an AVID-D protocol; the method comprises the following steps: designing an asynchronous batch processing distributed key generation protocol ABDKG-A with adaptive security by constructing an SSM; on the basis of an ABDKG-A protocol, an asynchronous batch processing distributed key generation protocol ABDKG-T with adaptive security is designed by using an ultra-reversible matrix technology. 本发明公开了一种异步环境下的批量高效分布式密钥生成方法，其特征在于：包括以下步骤：设计具有诚实方话语权的异步可验证信息散播协议AVID-D；在AVID-D协议基础上结合MVBA和加锁锁定机制设计具有中断可用性的并行异步可验证信息散播协议n-(n,t)-AVIDs；通过构造SSM，设计具有自适应安全性的异步批处理分布式密钥生成协议ABDKG
