Alice and Bob are unknown to each other. Alice wants to send an encrypted message to Bob. So it chooses a KDC which is known to both Alice and Bob (protocol in page 338). Alice and KDC have A5 (hexa) as a shared key. Bob and KDC have 4B (hexa) as a shared key. Alice sends a request to KDC to generate a session key so it can communicate with Bob. KDC generates 56(hexa) as a session key. Alice intends to send 13 (hexa) as a message to Bob. For simplicity assume that the encryption and decryption operations are simply XOR operation of the key with the message. Answer the following.
1. What information does KDC send to Alice? Show as hex characters.
2. What information does Alice send to Bob? Show as hexa characters.
3. What message does Bob retrieve after decryption? Show as hexa characters.

Answer:

ITS A SIMPLE ANSWER BUT THE PROBLEM IS TOO BIG!

Explanation:

The phishing email might contain a link which on clicking will take you to a fake web page. For example, the link might take you to a fake bank website which looks very legitimate but in reality is just a lookalike. If the victim falls for the scam and enters his/her account details on the website, the details will actually go to the hacker's server instead of going to the bank and the hacker will have all the information that the victim has provided on the website.

In the welding operations of a bicycle manufacturer, a bike frame has a long flow time. The set up for the bike frame is a 7 hour long operation. After the setup, the processing takes 6 hour(s). Finally, the bike frame waits in a storage space for 7 hours before sold. Determine the value-added percentage of the flow time for this bike frame. Round your answer to the nearest whole number for percentage and do NOT include the "%" sign in the answer. For example, if your answer is 17.7%, please answer 18. If your answer is 17.4%, please answer 17. No "%" sign. No letter. No symbols. No explanation. Just an integer number.

Answers

Answer:

Bike Frame Flow Time

The value-added percentage of the flow time for this bike frame is:

= 46.

Explanation:

a) Data and Calculations:

Bike Frame Flow Time:

Setup time = 7 hours

Processing time = 6 hours

Storage time = 7 hours

Flow time of the bike frame = 13 hours (7 + 6)

Value-added percentage of the flow time for this bike frame = 6/13 * 100

= 46%

b) Flow time represents the amount of time a bicycle frame spends in the manufacturing process from setup to end.  It is called the total processing time. Unless there is one path through the process, the flow time equals the length of the longest process path.  The storage time is not included in the flow time since it is not a manufacturing process.

The scale to fit group can be found in the page layout tab as it is used to deal with display of functionalities of a document and spreadsheet program. The scale to fit requires input in the width option which will dictate the width of the page in which to place the documents on. By specifying 1 for the width, this means that the document will be rescaled to fit on a single page. The automatic option may be selected for the height option which will allow the program to make an auto Decison in the shrinkage depending on the stated width value.
