Public-key cryptography

reasons we see these results is because the cryptographic software changes the security of that said organization. Data that was once open to everyone is now only accessible to those who have access or encryption keys. Some organizations have also experienced user complains. If encryption keys are lost the data that is encrypted could be rendered useless. The companies that implement cryptographic software also see an increase in costs. Overall the companies that have done these implementations…

To generate a public number, pick two prime numbers, such as 11 and 13. Calculate for m, in which m = (11 - 1)(13 - 1) = 10 x 12 = 120. Find a number not divisible by m, such as 7, the first public number. The second public number is derived from multiplying the two initial numbers, 11 x 13 = 143. The private number is formed using modular arithmetic with the first public number to find d, where 7d = 1 mod 120. So the private number is 103.…

The government thinks that digital things can be made so only they can access, but “When you build a fence around your house to keep out intruders you don’t leave a big hole in the fence for easy access to the police” ("Billions at stake"). The government is parasitically taking our privacy and always trying to take more from the people justifying that it is all in the name of national security. Mass surveillance is already put in place and now they want to ban encryption. The government 's…

Security is a buzz word for every aspect of your life. Financial, child protection, personal defense, work, and most importantly your personal information that exists. Everyone needs it and everyone will face it in some form in their lifetime. In today’s world identity theft is becoming more and more common. The headlines have been rampant with companies that have been breached and thousands of customer’s information stolen and used. So how do we stop it? What can we do to protect ourselves?…

The Security and Confidentiality policy is an important policy not just for the business but for students too as anything that disobeys orders can risk the safety of student accounts that actually hold personal information and student resources such as the shared area, if this gets corrupted then the college will face losing valuable lesson plans that have taken a long while to plan. As a college is a busy place, there is an increase chance of an intruder coming in and hacking systems to expose…

Jhon Woddy Ransomware short description: Jhon Woddy Ransomware is an updated version of M4N1F3STO Ransomware. Dozens of ransomware are similar to this ransomware like Cerber, Hakuna Matata, havoc, and many others. All of them encrypt the behavior or more or less the same - the request for the victim's file and fee. The only major difference is the size of the type of ransom and use of encryption technique but the distribution method is same. Why Jhon Woddy Ransomware is dangerous? Once this…

A COMPARITIVE STUDY OF NEAREST NEIGHBOUR ALGORITHM AND GENETIC ALGORITHM IN SOLVING TRAVELLING SALESMAN PROBLEM Ajaz Ahmed Khan Electronics and communication department SSGI FET Bhilai, India ajz70277@gmail.com Mrs. Himani Agrawal Electronics and communication department SSGI FET Bhilai, India Abstract—In this paper, we have used two algorithms, i.e. the Nearest Neighbor algorithm and Genetic Algorithm to solve the Travelling Salesman problem. The Travelling Salesman…

Introduction In the present times when we look at the Intelligence agencies, the first thing that strikes our mind is secrecy – the services must have the benefit of operational secrecy. Because the services work clandestinely and the nature of their tasks requires them to fulfil their obligations in secret, they are at odds with the principle of open society. In cases of these agencies, there arises a conflict between there operational need of secrecy and the democratic objective of…

The Aegis Secure Key 3.0 has military grade full disk AES 256-bit XTS hardware encryption and is FIPS 140-2 Level 3 validated. You unlock the drive by entering your 7-16 digit PIN before you connect it to your device that way hackers cannot use software on your device to capture your password, and it automatically locks when you unplug it. If an incorrect password is typed 20 consecutive times all the data and the encryption key are erased. It is also dust and water resistant as well as a wear…

it helps in reconstructing the activities of an intruder by inspecting the documented times of file accesses and recuperating erased documents. The most prominent components of TCT include the findkey tool which helps in in recovering cryptographic keys from files or a running process, the grave-robber tool which helps in capturing important information, the unrm and lazurus tools helpful in recovering deleted files and the ils and mactime tools helpful in displaying access patterns of dead or…
