To use data encryption algorithms in network communications, all parities must first agree on using the same secret keys
Rely on couriers
Set up a meeting to determine a secret key
Use postal service, email service, phone service
However, these conventional methods are inflexible for network communication applications
Public-key cryptography (PKC)
Invented in the 1970’s
Without the need of sharing prior secrets to distribute secret keys securely
Can also be used for authentication
Objectives of Chapter 15: To explain the need for a key-distribution center; to show how a KDC can create a session key; to show how two parties can use a symmetric-key agreement protocol to create a session key; to describe Kerberos as a KDC and an authentication protocol; to explain the need for certification authorities for public keys; to introduce the idea of a Public-Key Infrastructure (PKI) and explain some of its duties.

This paper provides a review of the steps and stages associated with project management according to the
Project Management Institute® (PMI). It is a primer for anyone new to the Project Management Body of
Knowledge® (PMBOK®) and who is preparing to take the PMP exam.
In order to understand how the Project Management Institute (PMI) recommends that projects be run it is nec-
essary to understand the project management life cycle. The project management life cycle is the framework
around which project management activities are structured.
In Oracle8 we saw the addition of bitmap indexes, function-based indexes, as well as reverse key indexes and star index structures. We also saw the Oracle SQL optimizer becoming more intelligent about the way indexes are used by SQL statements. In Oracle9i, we have the index skip scan, the and_equal hint to combine individual indexes into a contaminated index, as well as specialized bitmap access methods to improve the speed of data warehouse queries.
More complex networking services in Red Hat Linux require more advanced
administration methods. While graphical tools such as Network Configuration
(via the redhat-config-network command) are available to assist in configuring
all aspects of Linux networking, the best way to learn networking is by practicing with the key
command line utilities and associated configuration files.
