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…

Android’s latest version 5.0. Various cryptographic algorithms are used for encryption. It also uses hardware based storage for the key using Trusted Execution Environment (TEE) signing capability. It uses 128 bit AES as the encryption algorithm with Cipher Block Chaining and SHA256. In version 5.0, when the device is booted for the first time, a 128 bit master key is generated using which the data on the device is encrypted. This master key is then encrypted with the device password (a default…

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…

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…

Cryptography began as soon as language and writing were developed, some early forms were the use of hieroglyphics, or the use of secret messages on animal skins to tell stories or to pass along messages. These more primitive methods lead to the Cipher (or Caesar) disk where there were two rings of the alphabet and the inner ring could be moved around within the circle in order to give each outer alphabet characters a new corresponding letter (Ellison). This process was known as transposition,…

Security and integrity, as well as the privacy of user data, remain an important aspect of any computing-related business. Considering that all businesses have turned to technology in a bid to enhance efficiency, it is common to face security related issues. Cloud robotics which is one of the algorithmic processes is a good example of what can be attained using algorithms. This paper is bent on focusing on practical differences in which algorithms are used in solving problems (phishing) through…

The Counterfeit Coins Problem is a well-known complex search problem in mathematics as well as in computer science. It can be related to the data structure (such as binary tree) computer program, algorithm, Graph Theory, Therefore researching this problem is meaningful. The Counterfeit Coins problem can be described as given a set of n look-alike Coins containing One Counterfeit which is a bit heavier or lighter than the genuine Coins. The objective is to find the Counterfeit Coins in minimum…
