In this article, we make some research due to some problems of HECC, including the math background of hyperelliptic curves cryptography, the algorithm of divisor scalar multiplication, and providing a kind of general digital signature based on hyperelliptic curves cryptography.

为了确保这一系统的稳定性与安全性，HECC的几个主要参数的选取问题就起了很大的作用，本文对这几个参数选取作了详细介绍，并且归纳了求基点和求阶的方法。

Hyperelliptic curves cryptography is one kind surpassing of ellipse curve cryptography.

在同等安全水平下，HECC比ECC所用的基域小，并且在同样的定义域上，HECC可以提供更多的曲线，这样可以用于密码学中的安全的曲线的选项便增多了，由于这些优点使得HECC在近几年来，在密码界中受到越来越多的重视。

Security based on cryptography and authentication alone is not sufficient, because cryptography cannot prevent malicious or non-malicious attacks from internal adversaries or faulty nodes.

无线传感器网络有其资源受限的特点，单靠密码学和认证无法阻止网络内部的恶意或非恶意攻击以及节点的异常行为。

In the exploration of the self-dependent techniques of the cryptography, the Cellular Automata is viewed as the most potential of the kernel technique in the self-dependent techniques of the cryptography by its simple,regular and high parallel processing architecture which is suitable of VLSI implementation and its complicated dynamic properties.

在自主密码技术的探索中，细胞自动机特有的适合VLSI实现的简单、规则、高度并行的物理结构和复杂的动力学特性非常适合在密码学中的应用，被认为是密码技术自主化方面最有希望的核心技术之一。

This paper presents a one- way trapdoor function based on the favorable properties of ergodic matrices, then implements their applications in secret- key cryptography, hybrid cryptography, STS Protocol and Shamir Three-Pass Protocol.

单单研究单向函数是没有意义的，没有什么方法能够算出它，但是如果在单向函数中加一个条件，使得原先不可解的函数变为可解，那么对于加密就有重要的意义。

Quantum cryptography is the combination of classical cryptography and quantum mechanics. The characteristics of quantum mechanics, such as no-cloning theorem and Heisenberg's uncertainty principle, provide the perfect secrecy for quantum cryptographic communication.

量子密码学是密码学与量子力学结合的产物，利用量子不可克隆定理和海森堡测不准原理等量子特性，量子密码通信理论上已经证明是绝对安全。

这里包含了密码学的详细介绍，以及各种算法，相信对大家一定有用。

The finite field arithmetic is the base of cryptography and modular inversion is the kernel arithmetic operation.

有限域的运算是密码学的基础，而在有限域的所有运算中模逆运算是最核心也是最复杂的运算。

The dissecting of samples in group2 were difficult. The root of pulmonary artery and ascending aorta failed to be unfolded because fibrous tissue was tough, right and left fibrous trigone were too firm to be solved by hand. Cardiac muscle fibers couldn't be stripped along myofibrillar trajectory since they were prone to break because of their friability.

组2的心脏解剖困难，表现为纤维组织坚韧，游离肺动脉非常困难；徒手无法松解左、右纤维三角，肺动脉和主动脉根部的游离非常困难；心肌纤维坚硬、质脆，解剖时容易断离成碎块，无法沿纤维走行方向剥离。

We have battled against the odds in a province that has become increasingly violent.

我们对在一个争夺日益激烈省的可能性。
