Public-key cryptography

When it comes to password security, we are faced with a serious conundrum. While we want to remember the password, we still need to practice safe security with a good one. The trouble with the easier to remember passwords is that they are highly insecure. What can you do to combat this problem? When you are using uppercase and lowercase letters, symbols and numbers to compensate, you can use what is known as a passpoem to resolve the problem of remembering. As Marjan Ghazvininejad and Kevin…

Wason Selection tasks What if there are 4 cards on the table: A, K, 2 and 7. On one side of the card there is a number and on the other a letter. You have to decide which cards to turn in order to determine if the following statement is false: If a card has a vowel on one side, then it has an even number on the other side. This is called the Wason Selection task a famous reasoning puzzle (Dawson, Gilovich, Regan, 2002). The answer to this problem is cards A and 7 instead of the most commonly…

The article “Quantum Computer Comes Closer to Cracking RSA Encryption” written by Amy Nordrum, shows that Cryptography needs to be important, because of the fast developing of new technology. In her article Ms. Nordrum tells about computer scientists from the MIT which found a way to crack the RSA (Rivest, Shamir and Adleman)-Code. On the fact, that RSA Encryption is used in all our devices it is quite frightening to know that the government is maybe already using this kind of technology for…

1.Describe the key security enhancements in UMTS that overcome GSM design weaknesses? Ans: 1. Encryption algorithms used in GSM were not disclosed, aiming to achieve ‘security through obscurity’. Their shortcomings were discovered by reverse engineering an actual GSM phone. The design of algorithms was kept secret (it was disclosed only on a need-to-know basis, under and non-disclosure agreement, to GSM manufacturers). A secret authentication or encryption algorithm may be vulnerable since it…

of the semester was a silent film that would focus on someone or something involving a lock and a key while expressing an emotion. This project wasn’t a solo project, but instead involved working with one other person. The lock and key could be metaphoric or literal and from that concept we had to tell a story in twelve to fifteen shots. Our idea was to convey a young musician finding the right “key” on his guitar and “unlock” the excitement (which was our assigned emotion) inside of him. I…

Change Is Constant In the game My Personal GPS, I had to guide an avatar through a series of games that tested my learning skills and work habits. At the end of the level, you either passed and were awarded a key, or failed and had to retry the game. For some of these games, I didn 't receive a key on my first try and had to repeat the level until my skills matched my evaluation. This caused me to have to rethink my avatar’s actions and adapt to the different situations I was put in. I knew that…

Security is very essential to you as a homeowner. You need to optimize the security of your home as homeowner. There are many ways through which you can optimize the security of your home. Some of those ways include: installing electric gates in your home, fencing and so on. Did you know that keyless entry locks can help in optimizing the security of your home? Most homeowners have installed these locks in their homes. You will realize that burglars normally have evil motives of stealing your…

methodologies for evaluating impact of the Professional Training Corps (PTCs). Key Performance Indicators (KPIs) identified in such trials can help evaluate the effectiveness of the courses more effectively, especially considering the heterogeneous nature of the population. • PFS projects are multi-year, multi-party performance based contract and, hence, are required to be treated as such. The construction phase must bring together all the key parties involved in order to agree on specific…

prior decision, or a credible source. Research articles findings suggest that indeed there is a strong correlation between decision sidestepping and motivation to achieve closure. 1 What are the key issues the research set out to address? What are the key findings? Why are they important? Key issues were to prove that decision sidestepping occurs when person/persons are engaged in decision making that is unfamiliar and or bothersome. Indeed, researchers were able to prove that…

back, he found a note from his wife who died three weeks ago. The note read, “Under the bed there is a shoe box that contains a key to unlock the object on the floor.” The man stood and put the object on his chair and went to search under the bed as the note promised. He found the key inside the shoe box just as the note said. He went back to the object and put the key in the lock. Once he opened it there was another note that read “I’m sorry for not having the courage to tell you in person but…
