Theory & Practice of Cryptography & Network Security Protocols & Technologies

Book Abstract

Theory and Practice of Cryptography and Network Security Protocols and Technologies, This book contains the schemes, the sender and the receiver agree on the key they will use before establishing any secure communication session. Therefore, it is not possible for two persons who never met before to use such schemes directly. This also implies that in order to communicate with different persons, we must have a different key for each people. Requirement of large number of keys in these schemes make their key generation and management relatively more complex operations. However, symmetric schemes present the advantage of being very fast and they are used in applications where speed of execution is a paramount requirement.
