Cryptographic primitives are basic algorithms that used to create a protocol in the computer. The algorithm is the basic part of designing a encrypting systems. The security level of a computer system depends on the reliable level of the cryptographic primitives. Here is a detailed graphic on what is included and the types of cryptographic primitives in the CNG. Figure 6.1 CNG cryptographic primitives Among all the types of cryptographic primitives, one-way hashing function and encryption function are most commonly used in our daily life. One-way hashing function is used to identify data and encryption function is used to encrypt data. Hence, to explore the bottlenecks and future development of cryptographic primitives, we can focus on the characteristics of these two types. 5.1 One-way Hashing Function As the meaning in the surface, once the value of one-way hashing function is generated, you can not get the origin meaning of the value. It is usually used to identify a file’s integrity or the source of a software instead of check the value of the data. However, the limited function can cause troubles in the more complex society. The public needs comprehensive functional tools to help them deal with the daily life. For example, when a user is going to store a password when logging into a system, whether to use the method of hashing…
For example, when live acquisition technique is used, procedures that comprise of documenting all steps recommended for the technique applied, followed by imaging of the target evidence using a selected tool as long as the tool has full access to the system (Dykstra & Sherman, 2012). If the imaging software or tool cannot access the system, then decryption ought to be undertaken using the most appropriate decryption technique in order to remove cryptographic keys without modifying the data. A…
network forensic program that allows “real-time Internet interception, monitoring and forensics system that captures, decodes, and reconstructs various types of Internet traffic” (Detective, 2016). The third program is Paraben DS7 which is a forensic tool that focuses on mobile forensics. Need some work Hash Value A hash value is a “numerical identifier that can be assigned to a file” (JurisNet, 2008, p. 372). In digital forensics, the hash value or “hashing” “refers to the use of hash…
MR-RHVH framework apply the distributed structure of nodes using MapReduce, that equally partition data amongst Cassandra nodes using mapper and reducer functions. The MR-RHVH framework consists of three main layers, as shown in figure 2, Cassandra/Hadoop Cluster, MRRHVH, Cassandra/Hadoop Data Center and Hadoop/MapReduce applier. Cassandra clients ' nodes are distributed in this data center. Task Tracker and Data Node services run on each Cassandra node/client in the data center. The Task…
implemented in each level of the virtual hierarchical. Suppose the system contains n_od nodes that will be divided into number of Rendezvous geographic Zones (〖RG〗_Z) based on their geographic area. Each zone will have number of nodes n_od ranges from max┬iceli to min┬iflo depend on their area load. This will achieves O(log(AVG [max┬iceli , min┬iflo] ) running time. These zones are categorized as follows and so on. Then instead of hashing all the nodes in the system, we start hashing each…
rummaging around the fridge looking for the butter. “There!” I say grabbing the butter in the back of the fridge. I walk over to the sink. I grab a small chunk from the butter and rubbing it around my finger. ‘I hope this works.’ I think to myself as I try to pry the ring off my finger. “Oh my fu….”“Good morning honey, what are you doing down here already?” My mom interrupts me. “Oh no reason just felt like I should make breakfast today.” I say putting the butter behind my back. “Okay?…
Fundamental Theorem of Calculus The Fundamental Theorem of Calculus evaluate an antiderivative at the upper and lower limits of integration and take the difference. This theorem is separated into two parts. The first part is called the first fundamental theorem of calculus and states that one of the antiderivatives of some function may be obtained as the integral of the function with a variable bound of integration. The second part of the theorem, called the second fundamental theorem of…
John Gutmann was one of America’s most distinctive photographers. Gutmann was born in Germany where he became an artist. He later fled Germany due to the Nazi’s because he was a Jew. Gutmann moved to San Francisco and re-established himself as a photojournalist captivating the lives of Americans. He mainly took photographs of people who were imperfect like himself because of his Jewish nationality. Gutmann targeted the poor, circus folk, the gay community and the rich. Two of Gutmann’s works are…
The fundamental theorem of Calculus: The fundamental theorem of calculus asserts the interrelated properties of integration and differentiation. It says that a function when differentiated, can be brought back by integrating (anti-derivative) or a function when integrated, can be brought back by differentiation. First theorem: Let f be a function that is integrable on [a,x] for each x in [a,b], then let c be such that a≤c≤b and define a new function A as follows, A(x)=∫_c^x▒f(x)dt, if a≤x≤b.…
the equation & based off what I did I'm assuming that his possible answer came out not to be an real answer to his problem & that is mainly because the equation itself is not true when eighty one is inserted for the letter x in the default problem. Okay so basically for this particular problem we have to think of f of x as basically the y value if that makes sense. So this would mean that if you use addition for the number two & + to the letter y we will see the function go up by two. The…
