| 摘 要： | 给出一个支持多外围设备的基于身份的密钥隔离签名方案。方案中引入了n个不同且独立的外围设备,这n个外围设备以（k,n）秘密共享的方式共享密钥演化信息,其中任意k个外围设备都可以协助签名者完成临时私钥的更新,这样即使密钥频繁更新,也能保持较低的外围设备密钥泄露的机率,增强了系统防御密钥泄漏的能力。

| Abstract: | A new identity-based key-insulated signature scheme supporting multiple external devices was proposed.In this scheme,n different and independent devices were introduced,which share the key evolution information in the way of(k,n) threshold secret sharin and any k devices of which can help the user complete the update of the temporary private key.The security of this scheme is improved greatly. |
