摘要
将基于身份的公钥机制与轻量级CA(Certificate Authority)思想相结合,构建了一个基于身份及轻量级CA混合模型的传感器网络密码方案。该方案既克服了基于身份公钥机制中的第三方密钥托管问题,又简化了基于传统证书机制中产生、验证及管理公钥的复杂性。分析表明,方案可使公钥产生轻量化,公钥验证轻量化,密钥管理无需证书,且安全性高,可抵御无线环境下易于实施的多种攻击,适用于保障资源受限的无线网络中数据的机密性、完整性和不可否认性。
Combined identity-based system with the idea of lite-CA（Certificate Authority）,a scheme of identity-based and lightweight CA-based cryptography for wireless sensor network was proposed.The scheme not only avoids the drawback of private key escrow in the identity-based system,but also gains the advantage of simplifying complication of producing and verifying public key in traditional certificate-based CA system.Analysis shows that the scheme equips with characteristics of lite-producing public key,lite-verifying public key,certificate less,and high security which can defense some attacks easily carrying into wireless environment.It is applicable to be used in wireless network to gain data confidentiality,integrity,and non-refutation.
