摘要
针对MANET网络资源有限的特点,在其分级结构下提出一种基于身份的密钥管理方案。该方案结合基于身份的密码系统与椭圆曲线的离散对数难题、双线性对和加/解密技术。基于身份公钥的获取需要较少的计算量和通信量,不使用证书可以减少用户存储量,同时该方案的安全性建立在椭圆曲线机制和盲短签名技术上,有效解决了簇内节点的信任问题。通过分析证明,该方案在节约资源的同时具有较高的安全性。
According to the problem of the resources of MANET were limited,this paper proposed key management program based on identity in the hierarchical structure. It combined identity-based cryptography and elliptic curve of the discrete logarithm problem,encryption,decryption and bilinear pair. Getting the public key of identity-based cryptography requires less computation and communication cost. No using of certificates could reduce the amount of user memory. Security of the scheme based on elliptic curve mechanisms and blind signature. It effectively solved the problem of trust between nodes in the same cluster. The results show that the scheme saves resources and has high security.
