| 摘 要： | 提出一种基于LUC公钥体制的分类多秘密共享方案,该方案使用各用户的私钥作为各自的秘密份额,秘密分发者不需要进行秘密份额的分配,整个系统不需要维护安全的信道,每个子组共享一个秘密,全体参与者共享一个总秘密,所有类型的秘密之和构成核心秘密,该方案能够有效地保管多个秘密,并且实现了对多个秘密的分类管理,其安全性是基于LUC密码体制与Sham ir门限秘密方案的安全性.

| Abstract: | A classified multi-secret sharing scheme based on the LUC cryptography is proposed,using the user＇s private-key as their secret share,the secret dealer does not need to distribute secrets,the system does not need to maintain security channel.Each sub-group share a secret,all participants share a total secret,all types of the secrets constitute the core secrets,this scheme can effectively keep various secrets and achieve classified management of multi-secret,its security is based on the LUC public key system and Shamir ＇s threshold secret sharing scheme. |

| Keywords: | threshold scheme LUC cryptosystem classified multi-secret sharing |
