| 摘 要： | 在现有自选子密钥的可验证秘密共享方案中，门限接入结构假定各参与者具有完全平等的地位，这在多数情况下难以满足。为此，基于双线性映射提出一种自选子密钥的可验证广义秘密共享方案。该方案适用于一般接入结构，参与者可同时共享多个秘密，且子密钥可被多次重复使用。分析结果表明，该方案具有正确性和安全性。

| Abstract: | Most previous verifiable secret sharing schemes with self-selecting sub-key are based on the access structure of threshold.Access structure of threshold assumes that all participants have the same level of power,which is almost impossible in most cases.Based on bilinear pairing,a verifiable general secret sharing scheme with self-selecting sub-key is proposed.The scheme can be applied to general access structure,every participant can share several secrets,and its sub-key can be reused for many times.Analysis result shows that the scheme has validity and security. |

| Keywords: | general access structure self-selecting sub-key verifiable general secret sharing bilinear mapping |
