Cryptography

WBAN or Wireless Body Area Network is a new technology that has been invented for monitoring health condition of an individual. This is fitted in the body of a person Wire Sensor Network or WSN is possible due improvement of sensor technology as well as computer miniaturization. As the data related to patients are stored in a WBAN it is imperative that security of the data must be maintained. Body Area Network is a system comprising of wireless network of sensors to monitor health designed for…

Moving Target Defense The current cybersecurity environment is based around a static defense that has been employed for the past few years to protect information systems (See Figure 6). Unfortunately, this cybersecurity paradigm is not effective against current and future cyber threats. According to Zheng (2014), the weakness of this cybersecurity approach is its passive and reactive nature towards safeguarding information systems. Additionally, this method also allows threat actors the time…

because these attackers had done their research and knew what credentials they would need to perform the attack, no matter how the information was stored they still would have been able to access it. The one thing that could have been done is using cryptography for all the employee’s, especially those whom can use their credentials to perform special task.…

Invasion of privacy refers primarily to an intrusion into another person’s private life without just cause. As stated above, there are valid reasons why these hidden cameras are useful. I believe that the negative consequences far outweigh the positive ones. First, keeping privacy in this age of video surveillance is a serious concern. In the old days of the television show, Candid Camera, or the most recent version, Punked, unsuspecting people were placed in awkward or embarrassing…

The purpose of this paper is to discuss the potential risk of connecting any computer to World Wide Web or any network. With they’re being many threats such as hackers and malicious virus’s; attacks are going to happen whether you’re an organization or just an online shopper. In this day and age it is more often that a security breach is most likely to happen on a personal computer than at a company because the home user is not as secure and the average user is not as “computer savvy”. With that…

1.2. Previous Work The first symmetric key schemes for keyword search over encrypted data are proposed in [27]. The authors consider a setting in which the sender of file encrypts each word of a file separately. Goh [15] proposed a method for secure index using Bloom filters and introduced the notion of semantic security against adaptive chosen-keyword attacks. Determining whether a file contains a keyword can be done securely in constant time. In the public key setting, Boneh et al.[5] first…

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,…
