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

REAL TIME POWER SYSTEM SECURITY ASSESSMENT USING ARTIFICIAL NEURAL NETWORKS REAL TIME POWER SYSTEM SECURITY ASSESSMENT USING ARTIFICIAL NEURAL NETWORKS Abstract Contingency analysis of a power system is a major activity in power system planning and operation. In general an outage of one transmission line or transformer may lead to over loads in other branches and/or sudden system voltage rise or drop. The traditional approach of security analysis known as exhaustive security analysis involving

Network Expansion The fundamental characteristics and components of the a network of communications is well put together and is suited to their needs to support three stores. The Kudler network is small and only automated at the store level. In analyzing the current network setup‚ a determination will be made on a new network design. This will better automate the network communications between all physical locations of Kudler Fine Foods. Kathy Kudler’s business is still growing with a

Introduction S ocial network industry started to expand rapidly after the year 1997 where the world first social network site‚ SixDegrees.com is being introduced to the public. Afterward there were many different types of sites being introduced to public. Social network sites (SNSs) can be define as web-based services that allow individuals to construct a public or semi-public profile within a bounded system‚ articulate a list of other users with whom they share a connection‚ and view and traverse

prehistoric times. The ancient Egyptians‚ Babylonians‚ and Greeks all used it. The purpose of the arch in these cultures‚ however‚ was limited to supporting small structures‚ such as storerooms‚ and people often used columns to support the roof. This design limited the size and scope of a building. As a result‚ builders could not construct extremely large palaces or government buildings. The ancient Romans created an arch that could support huge amounts of weight. How did the Romans accomplish this
