## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|Finding the Greatest Common Divisor

We now describe an algorithm credited to Euclid for easily finding the greatest common divisor of two integers (Figure 2.2). This algorithm has broad significance in cryptography. The explanation of the algorithm can be broken down into the following points:

1. Suppose we wish to determine the greatest common divisor $d$ of the integers $a$ and $b$; that is determine $d=\operatorname{gcd}(a, b)$. Because $\operatorname{gcd}(|a|,|b|)=\operatorname{gcd}(a, b)$, there is no harm in assuming $a \geq b>0$.
2. Dividing $a$ by $b$ and applying the division algorithm, we can state:
$$a=q_1 b+r_1 \quad 0 \leq r_1<b$$
3. First consider the case in which $r_1=0$. Therefore $b$ divides $a$ and clearly no larger number divides both $b$ and $a$, because that number would be larger than $b$. So we have $d=\operatorname{gcd}(a, b)=b$.
4. The other possibility from Equation (2.2) is $r_1 \neq 0$. For this case, we can state that $d \mid r_1$. This is due to the basic properties of divisibility: the relations $d \mid a$ and $d \mid b$ together imply that $d \mid\left(a-q_1 b\right)$, which is the same as $d \mid r_1$.
5. Before proceeding with the Euclidian algorithm, we need to answer the question: What is the $\operatorname{gcd}\left(b, r_1\right)$ ? We know that $d \mid b$ and $d \mid r_1$. Now take any arbitrary integer $c$ that divides both $b$ and $r_1$. Therefore, $c \mid\left(q_1 b+r_1\right)=a$. Because $c$ divides both $a$ and $b$, we must have $c \leq d$, which is the greatest common divisor of $a$ and $b$. Therefore $d=\operatorname{gcd}\left(b, r_1\right)$.

## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|PRIME NUMBERS

A central concern of number theory is the study of prime numbers. Indeed, whole books have been written on the subject (e.g., [CRAN01], [RIBE96]). In this section, we provide an overview relevant to the concerns of this book.

An integer $p>1$ is a prime number if and only if its only divisors ${ }^5$ are $\pm 1$ and $\pm p$. All numbers other than $\pm 1$ and the prime numbers are composite numbers. In other words, composite numbers are those which are the product of at least two prime numbers. Prime numbers play a critical role in number theory and in the techniques discussed in this chapter. Table $2.5$ shows the primes less than 2000 . Note the way the primes are distributed. In particular, note the number of primes in each range of 100 numbers.
Any integer $a>1$ can be factored in a unique way as
$$a=p_1^{a_1} \times p_2^{a_2} \times \cdots \times p_t^{a_2}$$
where $p_1<p_2<\ldots<p_t$ are prime numbers and where each $a_i$ is a positive integer. This is known as the fundamental theorem of arithmetic; a proof can be found in any text on number theory.
\begin{aligned} 91 & =7 \times 13 \ 3600 & =2^4 \times 3^2 \times 5^2 \ 11011 & =7 \times 11^2 \times 13 \end{aligned}
It is useful for what follows to express Equation (2.9) another way. If $\mathrm{P}$ is the set of all prime numbers, then any positive integer $a$ can be written uniquely in the following form:
$$a=\prod_{p \in \mathrm{P}} p^{a_p} \quad \text { where each } a_p \geq 0$$

## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|Finding the Greatest Common Divisor

1. 假设我们莃望确定最大公约数 $d$ 整数的 $a$ 和 $b$; 那就是确定 $d=\operatorname{gcd}(a, b)$. 因为 $\operatorname{gcd}(|a|,|b|)=\operatorname{gcd}(a, b)$ ，假设没有坏处 $a \geq b>0$.
2. 划分 $a$ 经过 $b$ 并应用除法算法，我们可以声明:
$$a=q_1 b+r_1 \quad 0 \leq r_1<b$$
3. 首先考虑以下情况 $r_1=0$. 所以 $b$ 分裂 $a$ 显然没有更大的数字将两者分开 $b$ 和 $a$ ，因为这个数字会大 于 $b$. 所以我们有 $d=\operatorname{gcd}(a, b)=b$.
4. 等式 (2.2) 的另一种可能性是 $r_1 \neq 0$. 对于这种情况，我们可以说 $d \mid r_1$. 这是由于可分性的基 本属性：关系 $d \mid a$ 和 $d \mid b$ 在一起意味着 $d \mid\left(a-q_1 b\right)$ ，这与 $d \mid r_1$.
5. 在继续使用欧几里德算法之前，我们需要回答这个问题: 什么是 $\operatorname{gcd}\left(b, r_1\right)$ ? 我们知道 $d \mid b$ 和 $d \mid r_1$. 现在取任意整数 $c$ 将两者分开 $b$ 和 $r_1$. 所以， $c \mid\left(q_1 b+r_1\right)=a$. 因为 $c$ 将两者分开 $a$ 和 $b$ ， 我们必须有 $c \leq d$, 这是的最大公约数 $a$ 和 $b$. 所以 $d=\operatorname{gcd}\left(b, r_1\right)$.

## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|NETWORK SECURITYY

Network security is a broad term that encompasses security of the communications pathways of the network and the security of network devices and devices attached to the network (Figure 1.5).
Communications Security
In the context of network security, communications security deals with the protection of communications through the network, including measures to protect against both passive and active attacks (Figure $1.3$ ).

Communications security is primarily implemented using network protocols. A network protocol consists of the format and procedures that governs the transmitting and receiving of data between points in a network. A protocol defines the structure of the individual data units (e.g., packets) and the control commands that manage the data transfer.

With respect to network security, a security protocol may be an enhancement that is part of an existing protocol or a standalone protocol. Examples of the former are IPsec, which is part of the Internet Protocol (IP) and IEEE 802.11i, which is part of the IEEE 802.11 Wi-Fi standard. Examples of the latter are Transport Layer Security (TLS) and Secure Shell (SSH). Part Six examines these and other secure network protocols.

One common characteristic of all of these protocols is that they use a number of cryptographic algorithms as part of the mechanism to provide security.
Device Security
The other aspect of network security is the protection of network devices, such as routers and switches, and end systems connected to the network, such as client systems and servers. The primary security concerns are intruders that gain access to the system to perform unauthorized actions, insert malicious software (malware), or overwhelm system resources to diminish availability. Three types of device security are noteworthy:

• Firewall: A hardware and/or software capability that limits access between a network and devices attached to the network, in accordance with a specific security policy. The firewall acts as a filter that permits or denies data traffic, both incoming and outgoing, using a set of rules based on traffic content and/ or traffic pattern.
Intrusion detection: Hardware or software products that gather and analyze information from various areas within a computer or a network for the purpose of finding, and providing real-time or near-real-time warning of, attempts to access system resources in an unauthorized manner.
• Intrusion prevention: Hardware or software products designed to detect intrusive activity and attempt to stop the activity, ideally before it reaches its target.
These device security capabilities are more closely related to the field of computer security than network security. Accordingly, they are dealt with more briefly than communications security in Part Six. For a more detailed treatment, see [STAL18].

## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|TRUST AND TRUSTWORTHINESS

The concepts of trust and trustworthiness are key concepts in computer and network security [SCHN91]. It will be useful to look first at a generalized model of trust and trustworthiness, and then apply these concepts to the topic of information security.

One of the most widely accepted and most cited definitions of trust in the organizational science literature is from [MAYE95], which defines trust as follows: the willingness of a party to be vulnerable to the actions of another party based on the expectation that the other will perform a particular action important to the truster, irrespective of the ability to monitor or control that other party.
Three related concepts are relevant to a trust model:

• Trustworthiness: A characteristic of an entity that reflects the degree to which that entity is deserving of trust.
• Propensity to trust: A tendency to be willing to trust others across a broad spectrum of situations and trust targets. This suggests that every individual has some baseline level of trust that will influence the person’s willingness to rely on the words and actions of others.
Risk: A measure of the extent to which an entity is threatened by a potential circumstance or event, and typically a function of 1) the adverse impacts that would arise if the circumstance or event occurs; and 2) the likelihood of occurrence.

Figure 1.6, adapted from [MAYE95], illustrates the relationship among these concepts. Trust is a function of the truster’s propensity to trust and the perceived trustworthiness of the trustee. Propensity can also be expressed as the level of risk that an entity (individual or organization) is prepared to tolerate.

Typically, a truster uses a number of factors to establish the trustworthiness of an entity. Three general factors are commonly cited:

Ability: Also referred to as competence, this relates to the potential ability of the evaluated entity to do a given task or be entrusted with given information.

• Benevolence: This implies a disposition of goodwill towards the trusting party. That is, a trustworthy party does not intend to cause harm to the trusting party.
Integrity: This can be defined as the truster’s perception that the trustee adheres to a set of principles that the truster finds acceptable. Integrity implies that a benevolent party takes such measures are necessary to assure that it in fact does not cause harm to the trusting party.

The goal of trust, in the model of Figure $1.6$, is to determine what course of action, if any, the trusting party is willing to take in relation to the trusted party. Based on the level of trust, and the perceived risk, the trusting party may decide to take some action that involves some degree of risk taking. The outcome of the risk taking could be a reliance on the trusted party to perform some action or the disclosure of information to the trusted party with the expectation that the information will be protected as agreed between the parties.

• 防火墙：一种硬件和/或软件功能，可根据特定的安全策略限制网络和连接到网络的设备之间的访问。防火墙充当过滤器，使用一组基于流量内容和/或流量模式的规则来允许或拒绝传入和传出的数据流量。
入侵检测：从计算机或网络的各个区域收集和分析信息的硬件或软件产品，目的是发现以未经授权的方式访问系统资源的企图，并提供实时或接近实时的警告.
• 入侵防御：旨在检测入侵活动并尝试阻止活动的硬件或软件产品，最好是在它到达目标之前。
这些设备安全能力与计算机安全领域的关系比网络安全更密切。因此，它们的处理比第六部分中的通信安全更简单。有关更详细的处理，请参阅 [STAL18]。

## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|CYBERSECURITY, INFORMATION SECURITY

As subsets of cybersecurity, we can define the following:
Information security: This term refers to preservation of confidentiality, integrity, and availability of information. In addition, other properties, such as authenticity, accountability, nonrepudiation, and reliability can also be involved.

• Network security: This term refers to protection of networks and their service from unauthorized modification, destruction, or disclosure, and provision of assurance that the network performs its critical functions correctly and there are no harmful side effects.

Cybersecurity encompasses information security, with respect to electronic information, and network security. Information security also is concerned with physical (e.g., paper-based) information. However, in practice, the terms cybersecurity and information security are often used interchangeably.
Security Objectives
The cybersecurity definition introduces three key objectives that are at the heart of information and network security:
Confidentiality: This term covers two related concepts:

• Data ${ }^1$ confidentiality: Assures that private or confidential information is not made available or disclosed to unauthorized individuals.
• Privacy: Assures that individuals control or influence what information related to them may be collected and stored and by whom and to whom that information may be disclosed.
Integrity: This term covers two related concepts:
• Data integrity: Assures that data (both stored and in transmitted packets) and programs are changed only in a specified and authorized manner. This concept also encompasses data authenticity, which means that a digital object is indeed what it claims to be or what it is claimed to be, and nonrepudiation, which is assurance that the sender of information is provided with proof of delivery and the recipient is provided with proof of the sender’s identity, so neither can later deny having processed the information.
• System integrity: Assures that a system performs its intended function in an unimpaired manner, free from deliberate or inadvertent unauthorized manipulation of the system.
• Availability: Assures that systems work promptly and service is not denied to authorized users.

## 计算机代写|密码学与系统安全代写Cryptography and System Security代考|THE OSI SECURITY ARCHITECTURE

To assess effectively the security needs of an organization and to evaluate and choose various security products and policies, the manager responsible for security needs some systematic way of defining the requirements for security and characterizing the approaches to satisfying those requirements. This is difficult enough in a centralized data processing environment; with the use of local and wide area networks, the problems are compounded.

ITU-T Recommendation X.800, Security Architecture for OSI, defines such a systematic approach. The open systems interconnection (OSI) security architecture is useful to managers as a way of organizing the task of providing security. Furthermore, because this architecture was developed as an international standard, computer and communications vendors have developed security features for their products and services that relate to this structured definition of services and mechanisms.

For our purposes, the OSI security architecture provides a useful, if abstract, overview of many of the concepts that this book deals with. The OSI security architecture focuses on security attacks, mechanisms, and services. These can be defined briefly as:

Security attack: Any action that compromises the security of information owned by an organization.
Security mechanism: A process (or a device incorporating such a process) that is designed to detect, prevent, or recover from a security attack.
Security service: A processing or communication service that enhances the security of the data processing systems and the information transfers of an organization. The services are intended to counter security attacks, and they make use of one or more security mechanisms to provide the service.

In the literature, the terms threat and attack are commonly used, with the following meanings:

• Threat: Any circumstance or event with the potential to adversely impact organizational operations (including mission, functions, image, or reputation), organizational assets, individuals, other organizations, or the Nation through an information system via unauthorized access, destruction, disclosure, modification of information, and/or denial of service.
• Attack: Any kind of malicious activity that attempts to collect, disrupt, deny, degrade, or destroy information system resources or the information itself.
The following three sections provide an overview of the concepts of attacks, services, and mechanisms. The key concepts that are covered are summarized in Figure $1.2$.
