...NATIONAL UNIVERSITY OF RWANDA FACULTY OF APPLIED SCIENCES DEPARTMENT OF COMPUTER SCIENCE ACADEMIC YEAR 2011 Performance analysis of Encryption/Decryption algorithms using SimpleScalar By: MANIRIHO Malachie and NIZEYIMANA Jean-Paul Supervisor: Dr.-Ing. NIYONKURU Adronis Huye, 2011 CHAPTER ONE: GENERAL INTRODUCTION 1.1. BACKGROUND TO THE STUDY There are various security measures that can be imposed in order to secure the information stored. As more and more technologies evolve, an irresponsible person may try to find a way to excavate any loopholes within the system in order to penetrate into the heart of its weaknesses. This is due to the fact that human-made designs can also be broken by another human. Thus, over time security measures must constantly be reviewed and strengthened in order to combat hackers or culprits hot on the heels of system developers who are also using high technologies. One of the means to secure the data is to apply a secret code of encryption. By having it encrypted, the sender can pass the data to the receiver and only the receiver or authorized personnel can have access to the data provided they have been given a key by the sender to decrypt it in order for them to view the information. Thus, without having the right key, nobody is able to read the encrypted data received or stored. Even if hackers or unauthorized person managed to intercept or steal the data, it would be...

...number______9538546______________________________________ Company selected ___________Sanofi / Genzyme_________________________________ Area/Issue Introduction and set-up Conclusion and overall answer to the question Development of the argument (including critical analysis of business model concept; understanding of the specific deal chosen) Comments Good, clear introduction Concise conclusion provides an overview of the deal – what about the Q ie the usefulness of the BM approach. A brief overview of some approaches to BM. You provide a clear statement about how you intend to use the concept. In practice, this gets a bit confused later as you don’t follow through in an entirely coherent way. Try to keep focused on the idea of the BM. You discuss Sanofi’s BM in various ways to explain basic principles and how things have been changing. What is a ‘more diversified and continuous’ BM (p.4) can you explain this a bit more to help introduce the Genzyme deal. You outline various explanations for the deal, include the specific problems of Sanofi – these points are very nicely developed. Generally very clearly written. Your analysis is precise and authoritative. Some useful charts. Figure 3 seems to be missing. You could look at Sanofi’s performance in a bit more detail eg growth rates, margins, shareholder returns ie what was happening to viability and credibility in the run up to the deal? Generally you have a good analytical style, incorporating evidence into your argument. You could draw more widely...

...PROJECT SCOPE STATEMENT Project Cost and Schedule Control PM592 Instructor: Prof. Anoop Grover Submitted by Keerthi Kadam Date: September 09, 2011 Keller Graduate School of Management BACKGROUND/ PROJECT DESCRIPTION The IT team has developed a problem solving website for people who can discuss problems and get a solution. The purpose of this website is- a platform for people who are seeking help and to those people who can help. People can use this website to post questions by choosing category from various lists that are available. Any individual who has a solution to a problem can reply to the question and get in touch with the problem seeker to resolve it. In addition, there is a “ask a professional” tab where a professional can answer questions. This website will not work as a forum where people can make multiple posts, instead it will work as a problem solving website. The website will work from community to global level. As this website will be a work in progress, there will be many enhancements that will be done from time to time. Therefore, we will also do a gap analysis which will determine where the project is and where the project will be after 5 years. PROJECT SCOPE STATEMENT PROJECT OBJECTIVE To make the website more appealing in terms of design, user-friendliness, and increase sign ups to 10,000 users and generate revenue of $100,000 within 6 months at a cost not to exceed $100,000 while using the existing...

The term, christened by the US government, has been synonymous with the unintentional emissions of electrical and electromagnetic energy from a cryptographic device. TEMPEST dates back to the late 19th century when the telephone was invented and during the First World War when “crosstalk”, conversation through single-wire cables of the telegraph, was exploited by spies to reveal the intelligence of the enemy. In particular, what is being tested is the resistivity of the device component and cryptographic system against cryptanalysis. In other words, the TEMPEST evaluation tests the sensitivity of the device component toward power and electromagnetic analysis attacks. The possibility that someone can intercept and interpret those electromagnetic radiations to reconstruct the exact information poses a serious security issue because it jeopardizes confidentiality and secrecy. An attacker usually employs statistical analysis, signal processing, and artificial intelligence techniques to decipher the...

...IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS, VOL. 18, NO. 3, MARCH 2000 535 Performance Analysis of the IEEE 802.11 Distributed Coordination Function Giuseppe Bianchi Abstract—Recently, the IEEE has standardized the 802.11 protocol for Wireless Local Area Networks. The primary medium access control (MAC) technique of 802.11 is called distributed coordination function (DCF). DCF is a carrier sense multiple access with collision avoidance (CSMA/CA) scheme with binary slotted exponential backoff. This paper provides a simple, but nevertheless extremely accurate, analytical model to compute the 802.11 DCF throughput, in the assumption of finite number of terminals and ideal channel conditions. The proposed analysis applies to both the packet transmission schemes employed by DCF, namely, the basic access and the RTS/CTS access mechanisms. In addition, it also applies to a combination of the two schemes, in which packets longer than a given threshold are transmitted according to the RTS/CTS mechanism. By means of the proposed model, in this paper we provide an extensive throughput performance evaluation of both access mechanisms of the 802.11 protocol. Index Terms—802.11, collision avoidance, CSMA, performance evaluation. I. INTRODUCTION N recent years, much interest has been involved in the design of wireless networks for local area communication [1], [2]. Study group 802.11 was formed under IEEE Project 802 to recommend an international standard for Wireless Local...

...Ransomware Discuss the threat When infected restricts you to access to a computer system. This will become more refined in its targets and methods. Experts predict that the variants of ransomware that hurt the security software that are installed within a computer may particularly target the endpoints which sign up with cloud-based storage solutions like Google Drive, Dropbox, OneDrive and many more. On detecting the endpoint, ransomware will exploit the stored personal credentials of the logged-in user and will even infect the cloud storage that is backed up. McAfee has warned that ransomware attackers will try out as many ways possible to shell out ransom payments from their victims. Degree of damage The most advanced and most damaging ransomware in the wild at the moment, specifically targeting U.S. businesses and individuals. It's a $70 million per year criminal enterprise. Its magnitude is now confirmed by law enforcement. Some quick math shows $18,145 in costs per victim, caused by network mitigation, network countermeasures, loss of productivity, legal fees, IT services, and/or the purchase of credit monitoring services for employees or customers. As you can see, the total costs of a ransomware infection goes well above just the ransom fee itself, which is usually around $500 but can go up to $10,000. What it attacked Ransomware is a type of malware that infects a computer and restricts a user’s access to the infected computer. This type of malware...
