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…

the topic is completed and addressed in the paper. To be sure that all components of the assignment paper are being addressed, the students can highlight and underline the key parts that are mandatory in including in the paper. These key parts are the thesis,…

but the door was locked. Henry searched the house for a key to unlock the door. He walked into his grandpa’s room which he had never been in before. He searched around the room, he lifted a few objects searching for the key. He was about to give up when he saw a metallic object protruding out from under one of the pillows on the bed. He lifted the pillow to find a silver key. Henry grabbed the key and hurriedly ran to the basement door. The key fit perfectly and the door swung open. It was dark,…

I asked who all showed up to The Catalina when you were there. He said Nubs, and some dude and some chick. Rocky said he does not know who they were. He gave Nubs the key, because he said they were going to go into his room and have some fun. Rocky said okay, I’ll let you all use my bed and my room. I said, so you let them into your room to do whatever they were going to do, have sex, whatever? He said yes. Rocky said that was what he was under the impression of is that they were going to use…

Everyone has secrets they want to protect. Whether it is on computers, on paper, or verbal, secret communication has been around since humans could first communicate. Cryptography is the way we can transmit secret messages so that only the person it is meant for can understand it. The art of coding and decoding messages has progressed immensely through time, and has become increasingly difficult to break with the use of technology. Cryptography’s evolution has transformed the computing world…

difficulty of using PGP encryption, and its limitation. What is PGP encryption and how does it work? PGP is an abbreviation for “Pretty Good Privacy.” It is a hybrid encryption since PGP is a combination of some best features of both original and public key cryptography. If you encrypt the plaintext using PGP, it firstly compresses the plaintext and by data compression, modem transmission time and disk space are saved. Also, data compression strengthens cryptographic…

habitat. He pulled out a set of keys on a ring and began thumbing through them. After a minute, He whispered, “I found it.” As he opened the door, we went in quietly. Carl said, “Follow me.” We followed Carl to the location the groundhog was sleeping. Again, Carl started thumbing through the ring of keys. When Carl found the keys, he said to us, “Please be very quiet, we do not want to wake up the groundhog.” Paul whispered to us, “He is the one jangling the keys and making all the…

social objectives. Key Issues: The zoo is facing a profitability concern where the revenue generated by visitors is only able to cover around 60 percent of overall expenses. Furthermore, when inflation is added to this important challenge, it subsequently leads to Chakraborty’s inability to invest in long-term conservational goals, INR 56.5 million worth of renovations required by CZA’s new rules and regulations, and the zoo’s “most valuable resource” – its employees. Other key issues to…
