移动自组网是一种新型的无线移动网络,安全性是限制其广泛应用的主要瓶颈.引入了一种适合于移动自组网的椭圆曲线门限签名加密方案,该方案不但能保证数据通信的私密性、完整性以及移动节点的安全认证,而且具有通信代价小、低运算复杂度以及健壮性等优点.
Mobile Ad Hoc Network (Manet) is a new kind of wireless mobile network, and security is the bottleneck constraining its applications. A secure signature encryption scheme suitable for Manet is introduced based on Elliptic curve cryptosystems. The scheme not only can protect the confidentiality and integrity of the data transmissions, and provide secure authentifications for mobile users as well, but also has some other advantages, such as less communication cost,low computing complexity and robustness, etc.
