For example, if: a = (k* p) + b Equation 3-1 and, if a = 32 is divided by p = 5, the result will be k = 6 with a remainder of b = 2, and it can be written as a is congruent to b modulo p = 5. This congruence is expressed as follows: Copyright © 2008, IGI Global. Copying or distributing in print or electronic forms without written permission of IGI Global is prohibited. Number Theory and Fnte Felds  a ≡ b mod p Equation 3-2 and it is read, a is congruent to b modulo p. Congruences with the same modulo can be added, subtracted, or multiplied (Ogilvy & Anderson, 1988).

This interface may or may not provide reliable delivery, and may be packet or bit-stream oriented. The flexibility of TCP/IP is that it can be used with almost any network interface available. 3 are some examples of the protocols working at the data layer. The data formatted at the data layer are called frames. Security Policies, Services, and Mechanisms Security Policies is a document or set of documents that states an organization’s intentions and decisions on what and how electronic information should be secured.

Once the connection is established, the session layer manages the dialogue in an orderly manner. A connection between users (or between two presentation layers) is called a session. When the session is established, the two ends must agree on authentication and a variety of options; for example, if the communication should be simplex, half-duplex, or full-duplex. The session layer often provides a facility by which a group of messages can be bracketed, so that none of them is delivered to the remote user until all of them arrive.
