摘　　要：现代密码学密码算法的安全性都基于密钥的安全性,而不是基于算法细节的安全性。为了保证密码产品的安全应用,设计并实现了一种基于门限方案的智能卡密钥管理系统,通过引入门限密码体制和基于智能卡的双向动态认证机制,有效地解决了密钥产生、存储、分配、应用过程中的安全性问题。In modern cryptography, the security of cryptography depends on the security of the cryptographic key. In order to ensure the security of eryptographie products, a smart card key management system based on threshold scheme was proposed and implemented in this paper. By introducing the threshold eryptosystem and the mutual dynamic authentication mechanisms based on smart card, the security problems of key generation, storage, distribution, and the security of the application process were solved effectively.
