Cryptographic Authentication for Real-Time Network Protocols1‚2 David L. Mills3 Abstract This paper describes a new security model and authentication scheme for distributed‚ real-time network protocols used in time synchronization and event scheduling applications. It outlines the design requirements of these protocols and why these requirements cannot be met using conventional cryptography and algorithms. It proposes a new design called autokey‚ which uses a combination of public-key cryptography

Measuring the Speed of Sound and Air using a Pulse-Echo Technique Purpose To determine the speed of sound in air using the pulse-echo experiment procedure‚ and comparing it to the predicted speed of sound in air using the measured air temperature of the classroom. Hypothesis I believe that the speed of sound it the air will be close to that of the predicted value. According to our predicted value‚ we should expect the speed of sound in the air to be at a speed of approximately 346 m/s. Materials

CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing

Wireless‚ What’s the Difference? The main difference between a wired and wireless data communication infrastructure is the existence of physical cabling. The same or similar techniques are employed for both types of data communication infrastructure in terms of the core elements of essential network services. The basic difference between a wired and a wireless network is self-explanatory. A wired network uses wires to communicate whereas a wireless network uses radio waves. Another difference and how one
