摘要
依托Shamir(t,n)秘密共享门限方案和椭圆曲线密码体制(ECC),给出了一个应用于移动自组网环境的部分分布式对密钥管理框架,提出了一种自适应网络规模的秘密门限值动态调整方案,在不改变系统私钥的情况下,设计了一种服务节点私钥份额更新方法。分析表明,框架具有高的安全性、强的灵活性、高的可靠性和小的计算量,有助于移动自组网的对密钥管理研究。
This paper proposed a partly distributed pair key management framework for mobile Ad hoc network（MANETS）,which combined Shamir（t,n） secret sharing scheme with elliptic curve cryptography（ECC）.Put a project up which could dynamically adjust the value of threshold according to scales of networks.And designed a method to update the private key shares of service nodes,which didn＇t need to change the private key.Analysis indicates that this framework is secure,flexible,reliable,lightweight and applicable for the characteristics of MANETS.
