查询词典 scheme

A security enhancement scheme is proposed to encounter the black hole attacks in aodv protocol . this scheme may solve the black hole problem and prevent personating the destination node to some degree .

针对移动adhoc网络aodv协议中所存在的黑洞攻击，提出了一种增强安全性的解决方案，该方案能在一定程度上解决黑洞问题并可防止假冒目的节点攻击。

This scheme combined the q-composite random key predistribution scheme and introduced the location information to enhance secure connection probability between nodes.

该方案结合q-composite随机密钥预分布模型，并且通过引入地理位置信息，有效提高了节点之间安全连通的概率。

The proposed key predistribution scheme has advantages over random key predistribution scheme in its security and only spends moderate computation cost so it is quite practical.

与随机密钥预分配方案相比，本方案在健壮性和安全性方面具有一定的优势，其计算和存储开销也不大，具有一定的实用性。

To further enhance the security and connectivity for wireless sensor networks,proposed an improved key management scheme.Introduced the scheme,a random key predistribution using multiple key spaces and multipath key reinforcement was based on group-based deployment model which in the paper of DU Wen-liang.

为了进一步提高无线传感器网络的安全连通性，在分析DU Wen-liang等人的group-based节点投放模型的基础上，提出了一种改进的密钥管理方案：多密钥空间与多路径增强相结合的随机密钥预分配方案。

This scheme is based on the PRIMAR protection scheme, adopt Blowfish algorithm to encrypt, use Hash function (SHA-1) and Cyclic Redundancy Check to make sure the data integrity, and adopt DSA signature.

该方案基于PRIMAR保护方案发展而来，采用Blowfish分组算法对海图信息加密保护，通过SHA-1哈希函数和CRC循环冗余校验确保传输数据的完整性，并采用DSA算法进行签名认证。

The scheme is not only as secure and effective as Rabin scheme, but also has not particular demand of the basic prime.

该方案在安全性，效率上与Rabin签名方案相同，但对素数地选取没有任何特殊的要求。

Nowadays most of researches on the multicast routing are how to generate multicast tree. In case of multicast tree failure, there need to re-route all of nodes behind the failure point so much as re-build the whole tree, this will deteriorate Quality-of-Service, on the other hand, it is insufferable in some multicast applications. We proposed a Fault-Tolerant multicast scheme to resolve this problem. Our scheme creates backup paths crosswise in the ramose node. It can reduce additional cost greatly and recover the failure of multicast tree rapidly.

现在关于多播路由的研究大多着眼于多播树的生成，一旦多播树出现故障，就需要对故障点以下的所有多播接收节点进行重新路由甚至对整个多播树进行重新构造，这一方面降低了服务质量，另一方面有些多播应用不允许长时间的中断，对此本文提出了一种多播容错方案，采用在分枝节点之间建立备份路径的措施，可以在很大程度上减少额外的代价，能够在最快的时间内恢复多播树的故障，并使得恢复后的多播树形状基本上没有改变。
