MD5 is a calculation that is utilized to confirm information trustworthiness through the formation of a 128-piece message process from information input (which might be a message of any length) that is asserted to be as one of a kind to that particular information as a unique mark is to the particular person. Proposed where a vast record must be "compacted" in a safe way before being scrambled with a private key under an open key cryptosystem such as PGP. There are a lot of applications and we…

Blown to Bits – 15 points each No, it shouldn’t be illegal to encrypt data. It should be legal because the Government shouldn’t have an automatic right to read anyone’s private messages/information at any time. One pro of end-to-end encryption is that data is secured when it travels from a source to its destination. It also offers high flexibility for user in selecting a data to encrypt. Another pro is that we can easily integrate with the existing solution. We can just add an…

Have you ever heard of Spy-Free or Spy-Proof Emails? Most of people do not know well about the importance of privacy in their email and even they realize its importance, they are not sensitive to it. Now, the world’s best-known email providers Yahoo, and Google put in a great deal of effort to encrypted email system. They will introduce a new secure email system in the near future. However, some experts bring up several problems of encrypted mail. Christopher Soghoian, a security and privacy…

In Kim, Kipling melded the genuine work of the Indian Survey Department with anecdotal English intelligence operations, which utilized Asian specialists with cryptonyms like The Mirza or E5, to develop a mixture association profoundly occupied with counterintelligence activities on the boondocks and inside the Indian subcontinent. Other than Colonel Creighton who, as Control, is normally English, Kipling's legends are all Asian: the Afghan stallion merchant, Mahbub Ali; the Indian master of…

In this way file is reconstructed back from its shares. The size of each piece is |F| / (n-k), where |F| is size of secret/data, which is smaller than size of each piece produced through algorithm explained in [52]. In this scheme, m-1 shares of file F may provide some information about F. So in this scheme it is advisable to encrypt F before dispersing it and decode it after reconstruction of the encrypted version. One possible attack on the security of the data dispersed among servers would be…

and opinions. What was the equipment used? The ciphers represent the pages of previous editions of Whitaker's Almanack. The first number represented the page number in the Almanac. The second number, C2, was the column number on the page in the book. The numbers that followed represented the word that was in the second column on the same page. How the use of forensics helped reach the final result in the case- The use of cipher enabled Holmes and Watson to decode the messages that…

Data insecurity Cloud Security Alliance (CSA) believes that the data is less secured when it is in use. There are different views of every organization. This is because every entity has its own experience and its opinion is based over it. The account might be high jacked, or there might be data breaches, or it is possible that it might be an inside job. The management or the owner is the first person who is responsible in case of any illegal activity. It is crucial to determine the reason of the…

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…

same IV sequence which is hazardous as attacker can take advantage of this thus making WEP vulnerable 3. No cryptographic integrity protection: Even though WEP uses non-cryptographic CRC to check the integrity of packets. When CRC is used with stream cipher is dangerous. 10. How can the attacker authenticate with a WiFi AP running WEP without possessing the right credentials? Ans: WEP uses shared key authentication involves the knowledge of shared WEP key by encrypting the challenge. Attacker…
