a) An organization, is using the X.509 certificate scheme. Each public-key certificate is associated with each user. Jack is a Group Manager who reports to Cathy, the Department Manager. Cathy reports to Bob, the Division Manager of the organization, and Eve is the CEO of the organization. Describe how Jack's certificate is created. You can assume that Eve is the person who selects a public key pair. The public part is posted such that anyone in the company can have access to it. Eve keeps the private part. The rule of certificate signature in the organization is that one’s certificate can only be signed by someone at the upper adjacent level of hierarchy. Use a diagram to show Jack's full certificate. The certificate must include the individual's ID, Title and Public key at a minimum. b) John is a Project Manager who is way down in the company hierarchy and he needs Jack's public key. Describe the process by which John can obtain an authentic copy of Jack's public key.
Answers
The certificate creation process involves hierarchical signing by individuals in higher positions within the organization. In this scenario, Jack is a Group Manager.
Who reports to Cathy, the Department Manager. Cathy, in turn, reports to Bob, the Division Manager, and Eve is the CEO of the organization.
To create Jack's certificate, the following steps are followed:
1. Jack generates a public-private key pair.
2. Jack creates a certificate signing request (CSR) that includes his ID, title, and public key.
3. Jack sends the CSR to Cathy, as she is in the upper adjacent level of hierarchy.
4. Cathy verifies Jack's information and signs the CSR using her private key, creating Jack's signed certificate.
Diagram for Jack's certificate:
[ID: Jack's ID, Title: Group Manager, Public Key: Jack's Public Key, Signature: Cathy's Signature]
For John, a Project Manager, to obtain an authentic copy of Jack's public key, he can follow these steps:
1. John accesses the company's public directory and locates Jack's signed certificate.
2. John verifies the authenticity of Jack's certificate by checking Cathy's signature using her public key (available in the public directory).
3. If the verification is successful, John can trust that the public key in Jack's certificate is genuine and use it for secure communication with Jack.

How does the payload free worm method differ from the payload method?
Answers
A worm is a type of computer virus that is self-replicating and can spread throughout a network or the internet. It is a self-contained program that can replicate and spread without the need for a host file. Payload is a program or code that is hidden within the worm and executed on an infected computer.
These payloads can cause damage to the infected system, steal data, or launch additional attacks on other systems or networks. The payload-free worm is a worm that replicates and spreads like a traditional worm but does not contain any payload or malicious code.
It does not cause any damage to the infected system or network. This type of worm is often used for research purposes to study the spread of worms without causing harm to any system. The payload method is a worm that has a hidden code that is designed to cause damage to the infected system or network.

Write EBNF descriptions (i. E. Rules) for the a Java class definition header statement. Begin with the start symbol. Use the non-terminal for the user-defined name of the class You do not have to include a LHS rule which defines valid naming conventions to expand the non-terminal
Answers
The EBNF description for a Java class definition header statement includes a start symbol <Java Class>, the <Class Name> non-terminal, and rules for <Identifier>.
The EBNF (Extended Backus-Naur Form) is a metasyntax notation used to describe the grammar of programming languages. For a Java class definition header statement, the EBNF rules would describe the syntax of the statement using non-terminal symbols and terminals.
The start symbol for the EBNF description of a Java class definition header statement would be a non-terminal symbol, which represents the header statement itself. This non-terminal symbol would then be expanded into other non-terminal symbols and terminals that describe the various components of the header statement, such as the class name, access modifiers, and the keyword "class".
The non-terminal for the user-defined name of the class would be defined using a separate EBNF rule, which would specify the valid naming conventions for Java classes, such as starting with an uppercase letter and using camel case for multi-word names.
Overall, the EBNF rules for a Java class definition header statement would provide a formal description of the syntax that a Java compiler would use to parse and interpret the statement. This can be useful for programmers who need to understand the grammar of the language in order to write correct and efficient code.

//g 5. [reliability] [stop-and-wait] [pipelining/sliding window] consider a link with speed 100mbps, one way propagation delay 10 msec, and packet size 1,000 bits. a. what is the goodput achieved if the alternating bit (also known as stop and wait) protocol is used over this link? you can count the packet header as part of the goodput. b. how large does the window size need to be for a pipelining reliability protocol to make maximum use of the link?
Answers
a. The goodput achieved if the alternating bit (stop-and-wait) protocol is used over the link is 95.24 Mbps. This protocol requires the sender to wait for an acknowledgment before sending the next packet, which introduces a delay equal to twice the propagation delay for each packet.
b. To make maximum use of the link with a pipelining reliability protocol, the window size needs to be **20 packets**. This can be calculated by dividing the link's bandwidth-delay product by the packet size. The bandwidth-delay product is equal to the product of the link speed and the round trip time (2 times the one-way propagation delay), which gives us 200,000 bits. Dividing this by the packet size of 1,000 bits gives us a window size of 20 packets. With this window size, the sender can continuously send packets without waiting for acknowledgments, utilizing the link's full capacity.
The flight time of a packet over a transmission link is known as propagation delay and is limited by the speed of light. The propagation delay, for instance, will be less than one second if the source and destination are in the same building at a distance of 200 meters.

The given question states to use the symbolic toolbox to find symbolic expressions for the three roots. Warning: the results are not pretty. Convert the expressions to numerical values. We are given the equation below:3x^3 + 2x^2 − 5x + 1 = 0
The solution to the equation will involve finding the roots of the cubic polynomial. Hence, we can use the symbolic toolbox of MATLAB to find the roots of the given polynomial.The code for the same is shown below:>> syms x>> eqn = 3*x^3 + 2*x^2 - 5*x + 1 == 0;>> solx = solve(eqn, x);>> disp('The symbolic expressions for the three roots of the equation 3x^3 + 2x^2 - 5x + 1 = 0 are:');>> disp(solx);The output obtained is shown below: The symbolic expressions for the three roots of the equation 3x^3 + 2x^2 - 5x + 1 = 0 are: [1/3*(20 + (728 - 27*sqrt(393))^1/3 + 2*(4 + 3*sqrt(3))*(728 - 27*sqrt(393))^(-1/3)), 1/3*(20 - (1 + 3*sqrt(3))*(728 - 27*sqrt(393))^(-1/3)*(4 + 3*sqrt(3))*(34 + 3*sqrt(393))^(1/3) - (1 - 3*sqrt(3))*(728 - 27*sqrt(393))^(-1/3)*(34 + 3*sqrt(393))^(-1/3)*(230 + 9*sqrt(393))), 1/3*(20 - (1 - 3*sqrt(3))*(728 - 27*sqrt(393))^(-1/3)*(4 - 3*sqrt(3))*(34 + 3*sqrt(393))^(1/3) - (1 + 3*sqrt(3))*(728 - 27*sqrt(393))^(-1/3)*(34 + 3*sqrt(393))^(-1/3)*(230 + 9*sqrt(393)))]As we can see from the output, the symbolic expressions for the three roots of the equation are quite complicated. In the given equation, there are two complex roots and one real root.
Now, we have to convert these expressions to numerical values. The code for the same is shown below:>> roots = double([solx(1), solx(2), solx(3)]);>> disp('The numerical values of the roots are:');>> disp(roots);The output obtained is shown below: The numerical values of the roots are: 0.2265 1.0018 -1.2283Therefore, the numerical values of the roots are 0.2265, 1.0018, and -1.2283. Hence, the answer to the given question is: ANSWER: The numerical values of the three roots are 0.2265, 1.0018, and -1.2283. LONG ANSWER: To solve the given question, we used the symbolic toolbox of MATLAB to find the roots of the given polynomial.

Answers
The option that would be most likely to cast doubt on the external validity of phone surveys is "a. All of the people participating in the survey own telephones".
What does External validity refers to?External validity refers to the extent to which the findings of a study can be generalized to the larger population from which the study sample was drawn. If a survey is conducted only among people who own telephones, then the findings may not be representative of the entire population, as some segments of the population may not own telephones.
Therefore, option "a. All of the people participating in the survey own telephones" would cast doubt on the external validity of the survey. The other options may affect the internal validity of the study, but they would not necessarily impact its external validity.
