查询词典 hash code

In order to reduce the cost of matching, we used multiple scale technique. 4. We presented a novel method of searching for similar fragments of 3D curves. with this method, a hash vector is associated with each fixed-length fragments of 3D sherd. Each vector consists of low frequence component of Fourier-Like spectrum for the distance between profile curve and the centroid.

依据样条曲线的基本理论，研究了基于B样条的轮廓曲线的匹配方法，给出了由轮廓曲线不变量曲率和挠率构造的相似不变量的选取以及基于相似矩阵的匹配算法，并对该算法的时间复杂度作了估计，同时，将多尺度技术引入到物体轮廓的匹配问题中。

If you are looking for an application to check more hash algorithms, then you can have a look at Checksum verifier.

如果你正在寻找一个应用程序，检查更多的散列算法，那么你可以在看校验和验证。

Experimental results show that the hash function based on the Web site achieves the goal of the distributed Web crawler.

单处理机系统受限于CPU的处理能力和磁盘存储的容量，不可能具备这种处理海量信息的能力，更不必说跟上Web信息的飞速增长了。

The key technologies of which are hash function zero knowledge proof and digital signature.

消息完整性及真实性认证是防止消息被篡改、删除、重放和伪造的一种有效方法，其关键技术为：哈希函数、零知识证明和数字签名。

Dev/urandom is similar, but when the store of entropy is running low, it'll return a cryptographically strong hash of what there is.

dev/urandom 基本相似，但是当存储大量图谱进行低级运算时，它将返回一个足够强度的密码哈希值。

In 2005, Di Xiao proposed an entire deniable protocol based on chaotic maps, which used chaotic model to a chaotic key exchange scheme and a chaotic hash function.

Di Xiao等人于2005年提出了一种基于混沌映射的可否认认证方案，该方案利用混沌模型分别构造了一个混沌****交换协议和公钥加密以及一个混沌Hash函数。

In this paper, by considering the convenience of consumers, we use group blind signature technology with the character of hash chain to create the dividable and anonymous e-cash. Thus the users can consume not only in the home mobile domain but also visit mobile domain without register and authentic. We use off-line e-cash to increase the efficiency of payment exchange. Under the fair principle of all participators, we set a convenient and secure mobile payment.

因此，以消费者使用上的最大便利性为考量，本研究利用群体盲签章加入杂凑链之特性的方式来产生可分割的匿名电子现金，让消费者不只可以在主系统业者的网域内作消费，当其到漫游业者的网域内消费时，也不需要额外的认证及注册过程，并采用离线验证的方式来增加付款交易的效率性，在考虑各角色公平的原则下，提供一个方便、安全的行动付款系统。

According to real-time requirement of stream data and losable characteristic of transportation, the thesis analysis existing stream data signature methods suc h as star-s haped tree-shaped and Golle chain. Considering the condition of limit ed resource of receiver, it proposes forward plac ed hash chain data signature sc h eme based on Gilbert-Elliot Network channel model and enhanc ed Golle chain stream data signature method.

本文针对流式数据实时性要求和传输中易丢包的特点，分析比较了现存的星型、树型、Golle链型等几种典型的流式数据签名方法，考虑到接收方资源有限的情况，基于Gilbert-Elliot网络通道模型，改进了Golle链型流式数据签名方法，提出了一种hash值前置流式数据签名方案。

But overnet v0.52 and a ed2ktool v0.4, ed2k-hash, give out the same result as mldonkey's.

我估计应该是ed在前几个版本的时候自行对ed2k协议做了点改动，而em则没有理会。

A distributed secure clustering protocol is proposed, in which the secure network initialization, random number broadcast from the base station and one-way hash chain are used to achieve the resiliency against possible attacks including node personating, cluster-head occupying, malicious cluster-member recruiting and multiple cluster-membership attacks.

针对成簇协议所面临的各种安全威胁，提出了一种分布式安全成簇协议，通过网络安全初始化、可信基站的随机数广播和单向密钥链技术来有效地抵御节点伪装和簇首占据攻击、簇成员恶意征募攻击和多重簇成员身份攻击。
