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

UMUC’s new building in Adelphi‚ MD will have to provide networking connectivity to students‚ professors‚ and staff. In order to begin the process of planning the new network‚ we will begin by planning the network IP addressing scheme. It is very important that the network IP addressing scheme be clearly defined in order for IT administrators to locate computers promptly. Also‚ in order to make it easier for the administrators‚ DHCP (Dynamic Host Configuration Protocol) will be used to assign

TCP/IP network management functions are most normally connected with the key protocol responsible for implementing the Simple Network Management Protocol (SNMP). Many people have heard of SNMP‚ and it is common for SNMP to be considered the way that network management is performed in TCP/IP. This is true to an extent‚ but is really an overview. The actual SNMP protocol is only one part of a higher-level network management strategy called the Internet Standard
