Watson 1.Introduction Watson is a Question Answering system developed by IBM to compete against human opponents in Jeopardy which is a well-known television quiz show with a twist. Contestants are asked to phrase the question of a given answer from a selected category. The game of Jeopardy is considered a hard game for computers given its unstructured nature of questions from a vast number of domains and types. 2.History Before the start of the Watson project the team at IBM worked on…

SSL: KSSL is a client side only implementation of SSLv3.0 Other versions, SSLv2.0 or SSLv3.1 (aka TLS1.0) are not currently supported since they are not used as frequently. The client only offers two cipher suites – RSA RC4 128 MD5 and RSA RC4 40 MD5 since they are fast and almost universally implemented by SSL servers from the very early days of the protocol. Client side authentication is not implemented because it is rarely used and requires (highly CPU intensive) private key RSA operations on…

Introduction The question that we have before us today is simply “why does cryptographic software fail”. The most important building blocks for secured computer systems are cryptographic algorithms and protocols. They are based on mathematical foundations that are solid and provide authentication confidentiality and integrity. It is very difficult to turn mathematical equations into working systems. This is usually where the cryptographic systems fail. Two actions to take that can help you…

Alan Turing was misunderstood, to say the least. The man we now regard as the father of modern computer science was heavily criticized and discouraged during his life for various reasons. Nonetheless, Turing was an incomparable mathematician way ahead of his time, and he made major contributions to the math and technology fields, helping win World War II and creating a path for modern computers to become a reality. We recognize him today with great honor and respect, but throughout his lifetime,…

Introduction Cryptography can be defined as the process of encrypting and decrypting data in order to keep the information protected from anyone other than the two (or more) people involved in the communication. Preventing unauthorized users from being able to read the information exchanged over an insecure channel, i.e. maintaining ‘privacy’ is one serious cryptographic problem, which is why it is essential for the communicating parties to share a key that is unknown to others. This key…

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…

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…
