Lab Assignment #1: Introduction to Encryption Algorithms CSEC 630 University of Maryland University College Professor Jingyu Zhang 1. Which tool or technique would be most effective for a cryptanalyst to use to decipher a text encrypted with the Caesar cipher, and why? The best analysis tool to break the Caesar cipher is histogram because it performs a statistical analysis on cipher text which shows the frequency of each letter used in the file. This can later be compared and matched to the frequency of letters in the English language. 2. What do you notice about the histogram results when text is encrypted with the Vigenère cipher in comparison to the results of the Caesar cipher? Why is this the case? Histogram simply …show more content…
7. Analyze the data encrypted with the RSA cipher. How does this encryption method compare to the other methods these Labs have covered? RSA is more secure than traditional ciphers. Histograms are completely random. The complexity of cipher will depend on the ley size that is used. The RSA uses an asymmetric encryption and this makes it more secure that the Symmetric encryption. Asymmetric uses a key for encryption and one for decryption while the other methods used symmetric encryption and this used one key for encryption and decryption. The longer they key is, the more secure and complex the cipher will be. This goes for both the symmetric and asymmetric encryption The disadvantage of RSA is that it takes up a lot more space and memory and will run slower. It needs more processing power and memory. 8. What are the advantages of the Hybrid RSA-AES cipher? How does this encryption method compare to the other methods the Lab has covered? Advantages of the Hybrid RSA-AES are many and one is that it still stays at the speed of symmetric encryption while protecting the data with the strength of asymmetric encryption. Because the symmetric encryption is about 100 % faster than asymmetric encryption this makes it more efficient and there are no sacrifices to security and the performance. This encryption uses the pros of each part of the encryptions. This

Many changes were implemented after WWII as well as agencies created, such as the United States Air Force. However, even though the Air Force was created after WWII it has not stayed the same, and has grown and evolved with the world. Executive Orders have not updated the DoD regulation with the earliest rendition dated 18 September 1969 which is an Army regulation and not DoD. The most recent update, renumbering and name change is reflected as Army Regulation 380-67, Personnel Security Program dated 7 October 1988.
3. (06.04) If you had lived during the time of Julius Caesar, would you have sided with Caesar or with the conspirators? Why?
In quadrants 1 and 2 how the amount and constituents of the fingerprint residue on the substrate affects the fingerprint image, is determined. In quadrant 1, excess sebum and moisture is first removed from the finger tips with the help of a clean cloth. In quadrant 2, fingertip is first wiped around the nose or forehead to create excess sebum. Quadrant 3 and 4 were used to compare the details between untreated and dusted fingerprint residues.
During this unit I learned how to share a project with fellow classmates to allow them to work on it at the same time as me. I also learned the three different ways to allow this, by either sharing it with them, sending them an invite or link through via email, or by copying the link and sending it them. When I used Google Docs in high school we just shared it with one another and could see when we were all on. We also used it when we presented, but I did not know with One Drive you could present online! I think that is one of the coolest tools ever! Not only can you work on these projects and documents together, but you can communicate with each other as well. I was also unaware of how many gigs of storage you get when you sign up for programs
Since 1400 to 1700, the population of the world has seen three periods that affect them; the renaissance period, the baroque period and the Rococo period. Each period has a different kind of paintings, a different kind of art, and a different way to affect the society.
Cassius was a member of the senate. In this quote it says some senators tried to restrain Caesar but he resisted and the result was Caesar’s death. One of the senators had to have been Cassius meaning he took part in the assassination of Caesar. In document A a quote from Cassius shows that he was clearly jealous of Caesar’s growing popularity among the lower class which may have been a motivation to kill Caesar.
I personally love the fact that OSHA is in place. I want to go home in the same way I came to work. I want to go to work knowing that my employer is making it safe and all precautions to keep me from getting a infectious disease are in place. Knowing there are standards that has to be followed and that the employer must provide the proper PPE for me to perform my job safely is a great reassurance for me. If we did not have OSHA in place the world would not be safe. OSHA helps prevent the spread of diseases and helps keep people safe. People wouldn't want to work around places that wasn't made to be safe. If they didn't have to follow rules some places might cut corners and cause problems .
As mentioned by Calloway in the beginning of the “Documents” section, it is important to consider that historians often disregard stories due to their lack of understanding and that these stories can provide insight into the lives of individuals who lived through certain times in history. As pointed out by Leslie Marmon Silko, origin stories should not be taken as fact. I think that viewpoint supports the idea of possible migrations.
I also entered up to two additional keywords for each of my keywords making sure I have spelled everything correctly before continuing.
After reading the course resources, answer questions 1-10. (10 points each) Please take time to answer each question completely.
Funny, smart, and anything the capitol people and game makers would be interested in. Caesar is a flashy outgoing capitol citizen that serves a distinct purpose in the book and contributes to a main theme violence and manipulation in reality TV. Caesar’s physical appearance and personality tie into that of the capitol’s and portrays how the capitol can manipulate people. This character is always changing his hair color and makeup to
Another document that was used was a secondary source. It was an article written in the Britannica Student Encyclopedia. It was written for the public to read and understand Julius Caesar. It was used to give a brief overview of Julius Caesar’s life. It talked about him as a person, the civil war that he was involved with, the march he lead, as well as his reputation. The article is moderately trustworthy
1. What are some of the emerging IT security technologies that should be considered in solving the Problem related to the case?
On his way to the Capitol one of Caesar?s followers learns of the plot against Caesar and writes a letter to warn him. He waits in the streets for Caesar to pass by. He asks Caesar to read his letter because of its importance, ?Hail, Caesar! Read this schedule? 3.1:3, ?O Caesar read mine first, for mine?s a suit that touches Caesar nearer. Read it, great Caesar? 3.1:6-7. Caesar disregards him, ?What touches us ourselves shall be last serv?d? 3.1:8. Caesar proceeds to the Capitol, upon arrival and after few words spoken Caesar is stabbed to death by the conspirators. This ends the reign of Julius Caesar and starts a war. Caesar established Rome into the society that it is today.
