RSA Algorithm in Cryptography and Network Security Tutorial RSA Algorithm RSA is an algorithm for public key cryptography RSA (RIvest Shamir Adleman) Algorithm was publicly described in 1977. Mathematical Background of RSA Algorithm Extended Euclidean algorithm Given x, find y, such that x.y=1 mod m. The extended Euclidean algorithm can efficiently findContinue Reading
Cryptography and Network Security Tutorial for Beginners with Examples Cryptography It is a science of converting a stream of text into coded form in such a way that that only the sender and receiver of the coded text can decode the text. Can decode the text. Now a days, computerContinue Reading
Security Services in Computer Network Security Tutorial with Examples Security Services These are two main categories of security services RFC 2828: It defines as a processing or communication service provided by a system to give a specific kind of protection to system resources. X.800: It defines as a service providedContinue Reading
Domain Name System Security Extensions Tutorial Notes with Examples Domain Name System (DNS) To identify an entity, TCP/IP protocol uses the IP address which uniquely identifies the connection of a host to the Internet. However, people refer to use names instead of address. Therefore, we need a system that canContinue Reading
Routing and Switching Basics for Cyber and Network Security Tutorial Routing and Network Security Routing is the process of selecting paths in a network along which to send network traffic. Routing is performed for man y kinds of network, including the telephone network, electronic data networks and transportation networks RoutingContinue Reading
Switching in Computer Network Tutorial Study Notes with Examples Switching Whenever, we have multiple devices we have a problem of how to connect them to make one-to-one communication possible. Two solutions could be like as given below Install a point-to-point connection between each pair of devices (Impractical and wasteful approach whenContinue Reading
Medium Access Control Sublayer Tutorial in Computer Network with Examples Medium Access Control Sublayer The protocols used to determine, who goes next on a multi-access channel belong to a sublayer of the data link layer. This sublayer is called medium access control sublayer. Channel Allocation Static Channel Allocation FDM (FrequencyContinue Reading
Flow Control in Computer Network Tutorial Study Notes with Examples Flow Control One important aspect of data link layer is flow control. Flow control refers to a set of procedures used to restrict the amount of data the sender can send before waiting for acknowledgement. Stop and Wait In thisContinue Reading
TCP or IP Protocol Suite Tutorial Study Notes for Beginners with Examples TCP/IP Protocol Suite The TCP/IP protocol suite used in the Internet, was developed prior to the OSI model. Therefore , the layers in the TCP/IP protocol suite do not exactly match those in the OSI model. The originalContinue Reading
