Hash

RQ 1 A function for one block of bits in a hash function is referred to as a compression function. RQ 2 The main arithmetic and logical functions in SHA algorithms include AND, OR, NOT, XOR and the circular shift. RQ 3 The requirement in the replacement of a hash function is to remove the existing hash function and the insertion of the desired function. RQ 4 A one-way function is an algorithm or a function that is used to turn a piece of text into a fixed string of digits and is nearly…

Beam search is an informed algorithm for searching a graph that extends the Breadth-First search (Jungwirth, 2006). The Breadth-First search is essentially a special-case Best-First search where the evaluation function, f(n) is the same as the heuristics function, h(n) (JONES, 2008). Therefore in order to properly discuss Beam search, there is the need for a brief introduction to Best-First algorithm. The Best-First search traverses a tree from top to bottom and searches for nodes on the same…

the high feeling when consumed. THC potency varies widely among plants. Different genetic strains have different potencies. Plants in some cases are bred to maximize potency. Cannabis is consumed in three main forms: marijuana flower, hashish, and hash oil. Marijuana flower is made from the flowers and leaves of the cannabis plant. It is the least potent of all the cannabis products and is usually smoked. It can also be incorporated into edible products like cookies or the ubiquitous pot…

for disaster from the very start, along with his new hobby of smoking hash slowly turns him into a criminal day by day. But Gantos doesn’t really want to be a criminal he feels as he…

Blockchain is a shared, distributed ledger that facilitates the process of recording transactions and tracking assets in a business network [1]. It is an incorruptible digital ledger of economic transactions that can be programmed to record not just financial transactions but can be applied to everything of value. Once the information is entered in Blockchain it cannot be erased, modified or tampered with. Everyone in the network will be able to write data/perform transactions but cannot modify…

same document identifier is encrypted multiple times, it will create different ciphertexts but all decrypted to the same value. Then DO creates one Bloom filter BF for each document, this filter consists of an array of x-bits, and uses q independent hash functions h1,...,hq. The filter allows the data owner to perform keyword searches efficiently, but could result in some false positive retrievals. A classical Bloom Filter may reveal information about the…

Can you imagine one single decision you make in your teens, influencing your life and leaving a lasting impact on who you are as a person? This happened in the memoir Hole in my Life by Jack Gantos. This story talks about his time that he spent in his late teens, about how he ended up in jail and even how he then ended up in college. However, the thing that made all these things possible was the choice he glossed over in the beginning, which was to move and live on his own. A choice while not…

Hash values were used during different phases. First, during the computer forensic examination procedure, the hash value is exhausted to guarantee that the analyzed copy has not been modified. A hash value is acquired of the imaged copy previous to the examination of data. c. Another purpose for hash values can be exploited to authenticate testimony presented in court testimony. One opinion noted that a “hash value” could be exercised to validate an electronic…

communication is intended for. The fit is possible through digital signatures principles. Thirdly, cryptography ensures message integrity. If poor security is present, the integrity of data may be lost even after authentication. Cryptography alongside the hash function ensures that messages retain their integrity by eliminating accidental or malicious altering. However even with the confirmation of confidentiality, message integrity and authentication the security is still imperfect with the…

unattainable through a healthy diet and exercise routine and have resorted women to lose weight in lethal manners. Internet subcultures have also been created to “motivate” women to lose the weight. Example of these subcultures include pro-ana websites and hash tags such as “#thinspiration and #thininspo, all of which are used to justify these eating disorders as a lifestyle instead of a problem. Although, America has one of the lowest BMI standards for women; countries such as France have…
