A comprehensive research has made in the application of elliptic curve based bilinear mapping in the group signature, security of bilinear mapping is established on the GAP group. Because the DDH problem is easy to solve in GAP, this fact results it is very difficult to design a bilinear mapping based group signature scheme which can satisfy anonymity and the tractability.

对基于椭圆曲线的双线性映射在群签名中的应用进行了深入的研究，由于双线性映射的安全性建立在GAP群上，而在GAP群上的DDH问题是容易求解的，这样导致在基于双线性映射的群签名方案设计中很难同时兼顾群签名的匿名性和可跟踪性。

Though analyzed the existing schemes, a bilinear mapping based group signature scheme with multi-security strategies proposed, the proposed scheme satisfy the all security requirements for group signature completely.

在对现有的方案进行分析的基础上，提出了一个具有多种安全策略的基于双线性映射的群签名方案，方案很好地满足了群签名的全部安全需求。

Multi-group signature scheme can be regarded as a kind of generalized group signature scheme.

Based on the key tree and the Chinese remainder theorem, a leveled group key management scheme in wireless networks is proposed. An efficient stateless and leveled group key management scheme focusing on the revocations of wireless nodes is also presented. The security, flexibility, and adaptability of these two schemes in wireless networks are analyzed.

针对无线网络的特点建立了一种基于密钥树和中国剩余定理的分级群组密钥管理方案，针对无线节点容易被捕获的问题提出了一种能够有效解决密钥撤销的无状态分级群组密钥管理方案，并且着重分析了这两种方案在无线网络中的安全性、可扩展性和适用性。
